We perform a spectroscopic search for broad Hα emitters at z ≈ 4–6 using deep JWST/NIRCam imaging and wide field slitless spectroscopy from the EIGER and FRESCO surveys. We identify 20 Hα lines at z = 4.2–5.5 that have broad components with line widths from ∼1200–3700 km s−1, contributing ∼30%–90% of the total line flux. We interpret these broad components as being powered by accretion onto SMBHs with implied masses ∼107–8M⊙. In the UV luminosity range MUV,AGN+host = −21 to −18, we measure number densities of ≈10−5 cMpc−3. This is an order of magnitude higher than expected from extrapolating quasar UV luminosity functions (LFs). Yet, such AGN are found in only <1% of star-forming galaxies at z ∼ 5. The number density discrepancy is much lower when compared to the broad Hα LF. The SMBH mass function agrees with large cosmological simulations. In two objects, we detect complex Hα profiles that we tentatively interpret as caused by absorption signatures from dense gas fueling SMBH growth and outflows. We may be witnessing early AGN feedback that will clear dust-free pathways through which more massive blue quasars are seen. We uncover a strong correlation between reddening and the fraction of total galaxy luminosity arising from faint AGN. This implies that early SMBH growth is highly obscured and that faint AGN are only minor contributors to cosmic reionization.","lang":"eng"}],"year":"2024","month":"03","isi":1,"date_updated":"2025-09-04T13:15:26Z"},{"DOAJ_listed":"1","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"title":"Tuning the Josephson diode response with an ac current","quality_controlled":"1","author":[{"last_name":"Seoane Souto","first_name":"Rubén","full_name":"Seoane Souto, Rubén"},{"last_name":"Leijnse","full_name":"Leijnse, Martin","first_name":"Martin"},{"full_name":"Schrade, Constantin","first_name":"Constantin","last_name":"Schrade"},{"first_name":"Marco","full_name":"Valentini, Marco","last_name":"Valentini","id":"C0BB2FAC-D767-11E9-B658-BC13E6697425"},{"first_name":"Georgios","full_name":"Katsaros, Georgios","orcid":"0000-0001-8342-202X","last_name":"Katsaros","id":"38DB5788-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Danon","full_name":"Danon, Jeroen","first_name":"Jeroen"}],"language":[{"iso":"eng"}],"status":"public","intvolume":" 6","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_number":"L022002","ddc":["530"],"date_created":"2024-04-14T22:01:02Z","article_type":"letter_note","has_accepted_license":"1","volume":6,"day":"01","_id":"15320","publication":"Physical Review Research","issue":"2","file_date_updated":"2024-04-17T07:14:53Z","department":[{"_id":"GeKa"}],"type":"journal_article","citation":{"short":"R.

Here, we theoretically explore how an alternating current bias can tune the response of such a diode. We show that for slow driving there is always a regime where the system can only carry zero-voltage dc current in one direction, thus effectively behaving as an ideal Josephson diode. Under fast driving, the diode efficiency is also tunable, although the ideal regime cannot be reached in this case. We also investigate the residual dissipation due to the time-dependent current bias and show that it remains small. All our conclusions are solely based on the critical current asymmetry of the junction, and are thus compatible with any Josephson diode."}],"scopus_import":"1","year":"2024"},{"abstract":[{"text":"We report JWST/NIRCam measurements of quasar host galaxy emissions and supermassive black hole (SMBH) masses for six quasars at 5.9 < z < 7.1 in the Emission-line galaxies and Intergalactic Gas in the Epoch of Reionization (EIGER) project. We obtain deep NIRCam imaging in the F115W, F200W, and F356W bands, as well as F356W grism spectroscopy of the quasars. We use bright unsaturated stars to construct models of the point-spread functions (PSFs) and estimate the errors of these PSFs. We then measure or constrain the fluxes and morphology of the quasar host galaxies by fitting the quasar images as a point source plus an exponential disk. We successfully detect the host galaxies of three quasars, which have host-to-quasar-flux ratios of ∼1%–5%. Spectral energy distribution fitting suggests that these quasar host galaxies have stellar masses of M* ≳ 1010M⊙. For quasars with host galaxy nondetections, we estimate the upper limits of their stellar masses. We use the grism spectra to measure the Hβ line profile and the continuum luminosity, then estimate the SMBH masses for the quasars. Our results indicate that the positive relation between SMBH masses and host galaxy stellar masses already exists at redshift z ≳ 6. The quasars in our sample show a high BH-to-stellar-mass ratio of MBH/M* ∼ 0.15, which is about ∼2 dex higher than local relations. We find that selection effects only contribute partially to the high MBH/M* ratios of high-redshift quasars. This result hints at a possible redshift evolution of the MBH–M* relation.","lang":"eng"}],"year":"2024","scopus_import":"1","date_updated":"2025-09-08T07:30:17Z","isi":1,"month":"05","date_published":"2024-05-01T00:00:00Z","publisher":"IOP Publishing","publication_status":"published","article_processing_charge":"Yes","file":[{"file_id":"15410","creator":"dernst","access_level":"open_access","relation":"main_file","date_created":"2024-05-21T11:13:25Z","content_type":"application/pdf","checksum":"47b428f6209d8a6f9869031d9cb8dae6","file_name":"2024_AstrophysicalJourn_Yue.pdf","file_size":4472346,"success":1,"date_updated":"2024-05-21T11:13:25Z"}],"oa_version":"Published Version","doi":"10.3847/1538-4357/ad3914","acknowledgement":"We thank the referee for the valuable comments on this paper.

Target RNA cleavage at regular intervals is characteristic of type III effector complexes6–8. Here, we determine the structures of the Synechocystis type III-Dv complex, an apparent evolutionary intermediate from multi-protein to single-protein type III effectors9,10, in pre- and post-cleavage states. The structures show how multi-subunit fusion proteins in the effector are tethered together in an unusual arrangement to assemble into an active and programmable RNA endonuclease and how the effector utilizes a distinct mechanism for target RNA seeding from other type III effectors. Using structural, biochemical, and quantum/classical molecular dynamics simulation, we study the structure and dynamics of the three catalytic sites, where a 2′-OH of the ribose on the target RNA acts as a nucleophile for in line self-cleavage of the upstream scissile phosphate. Strikingly, the arrangement at the catalytic residues of most type III complexes resembles the active site of ribozymes, including the hammerhead, pistol, and Varkud satellite ribozymes. Our work provides detailed molecular insight into the mechanisms of RNA targeting and cleavage by an important intermediate in the evolution of type III effector complexes."}],"date_updated":"2024-06-04T07:05:26Z","month":"04","date_published":"2024-04-18T00:00:00Z","main_file_link":[{"url":"https://doi.org/10.1038/s41467-024-47506-y","open_access":"1"}],"publisher":"Springer Nature","quality_controlled":"1","title":"RNA targeting and cleavage by the type III-Dv CRISPR effector complex","intvolume":" 15","status":"public","language":[{"iso":"eng"}],"author":[{"last_name":"Schwartz","first_name":"Evan A.","full_name":"Schwartz, Evan A."},{"id":"96aecfa5-8931-11ee-af30-aa6a5d6eee0e","orcid":"0000-0003-0456-0753","last_name":"Bravo","first_name":"Jack Peter Kelly","full_name":"Bravo, Jack Peter Kelly"},{"full_name":"Ahsan, Mohd","first_name":"Mohd","last_name":"Ahsan"},{"first_name":"Luis A.","full_name":"Macias, Luis A.","last_name":"Macias"},{"last_name":"McCafferty","full_name":"McCafferty, Caitlyn L.","first_name":"Caitlyn L."},{"last_name":"Dangerfield","first_name":"Tyler L.","full_name":"Dangerfield, Tyler L."},{"first_name":"Jada N.","full_name":"Walker, Jada N.","last_name":"Walker"},{"last_name":"Brodbelt","full_name":"Brodbelt, Jennifer S.","first_name":"Jennifer S."},{"full_name":"Palermo, Giulia","first_name":"Giulia","last_name":"Palermo"},{"last_name":"Fineran","full_name":"Fineran, Peter C.","first_name":"Peter C."},{"last_name":"Fagerlund","first_name":"Robert D.","full_name":"Fagerlund, Robert D."},{"first_name":"David W.","full_name":"Taylor, David W.","last_name":"Taylor"}],"external_id":{"pmid":["38637512"]},"article_type":"original","date_created":"2024-06-04T06:43:02Z","article_number":"3324","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","pmid":1,"volume":15},{"publisher":"AIP Publishing","date_published":"2024-06-01T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2210.15643"}],"abstract":[{"lang":"eng","text":"We consider the spectral radius of a large random matrix X with independent, identically distributed entries.

Other researchers, however, observe different, substantially more conservative numbers. In order to resolve this disagreement, the nonlinear Kerr index of a bulk sample of lead halide perovskite was measured directly by means of an interferometer. This approach has many advantages as compared to the more standard z-scan technique. In particular, this method allows studying the induced changes to the refractive index in a time-resolved manner, thus enabling to separate the different contributions to 𝑛2. The extracted 𝑛2 values for CsPbBr3 and MAPbBr3 at 𝜆≈1µ⁢m are 𝑛2=+2.1×10−14cm2/W and 𝑛2=+6×10−15cm2/W, respectively.

One pathway to these SMBHs proposes that supermassive stars born in pristine atomic cooling haloes yield massive seed BHs evolving to these early SMBHs. This scenario leads to an overly massive BH galaxy (OMBG), in which the BH to stellar mass ratio is initially Mbh/M* ≥ 1, well in excess of the typical values of ∼10−3 at low redshifts. Previously, we have investigated two massive seed BH candidates from the Renaissance simulation and found that they remain outliers on the Mbh–M* relation until the OMBG merges with a much more massive halo at z = 8. In this work, we use Monte-Carlo merger trees to investigate the evolution of the Mbh–M* relation for 50 000 protogalaxies hosting massive BH seeds, across 10 000 trees that merge into a 1012 M⊙ halo at z = 6. We find that up to 60 per cent (depending on growth parameters) of these OMBGs remain strong outliers for several 100 Myr, down to redshifts detectable with JWST and with sensitive X-ray telescopes. This represents a way to diagnose the massive-seed formation pathway for early SMBHs. We expect to find ∼0.1–1 of these objects per JWST Near Infrared Camera (NIRCam) field per unit redshift at z ≳ 6. Recently detected SMBHs with masses of ∼107 M⊙ and low-inferred stellar-mass hosts may be examples of this population.","lang":"eng"}],"year":"2024","publisher":"Oxford University Press","date_published":"2024-06-13T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/https://doi.org/10.1093/mnras/stae1449"}],"article_processing_charge":"No","publication_status":"published","oa_version":"Published Version"},{"type":"dissertation","department":[{"_id":"GradSch"},{"_id":"NiBa"}],"citation":{"ista":"Surendranadh P. 2024.

In this regard, a key question is how genetically\r\ndistinct populations evolve in the face of gene flow, thereby generating genetic and\r\nphenotypic divergence and reproductive isolation (RI). This requires quantifying the role\r\nand relative contributions of prezygotic and postzygotic isolating mechanisms on the\r\nreduction of gene exchange between populations, and identifying regions in the genome\r\nthat mediate RI, which is often polygenic. Further, this needs distinguishing neutral and\r\nselected regions in the genome, and discerning how selection influences patterns of neutral\r\ndivergence.\r\nPopulation structure, defined as any deviation from panmixia, such as geographic distribution, movement and mating patterns of individuals, influences how genetic variation is\r\nstructured in space and shapes the neutral null model. Availability of large scale spatial\r\ngenomic datasets now enables us to detect signatures of population structure in genetic\r\ndata and infer population genetic parameters. Such inferences are crucial and have wide\r\napplications in biodiversity, conservation genetics, population management and medical\r\ngenetics. However, inferences are based on assumptions that do not always match the\r\ncomplex reality, thus leading to erroneous conclusions. Moreover, the role and interaction\r\nof heterogeneous population density and dispersal, which are ubiquitous in nature, has\r\nbeen challenging to study owing to their mathematical complexity. In such scenarios,\r\nfeedback between theory, data and simulations can prove to be useful.\r\nIn this thesis, I examine the effect of population structure on neutral genetic variation\r\nand barriers to gene exchange in hybridising populations, thereby bridging together the\r\nfields of spatial population genetics and speciation.\r\nDespite being a key concept in speciation, reproductive isolation (RI) lacks a quantitative\r\ndefinition and has been used and measured differently across different fields. Chapter 2\r\ngives a quantitative definition of RI, in terms of the effect of genetic differences on gene\r\nflow. We give analytical predictions for RI in a range of scenarios, in terms of effective migration rates for discrete populations and barrier strength for continuous populations.\r\nIn addition to this, we discuss current measures of RI and their limitations, and propose\r\nthe need for new measures that combine organismal and genetic perspectives of RI.\r\nIn chapter 3, I examine the combined effect of assortative mating, sexual selection\r\nand viability selection on RI. For this, we consider a polygenic ‘magic’ trait under a\r\nmainland-island model. We obtain novel theoretical predictions for molecular divergence\r\nin terms of effective migration rates, which bears a simple relationship to measurable\r\nfitness components of migrants and various early generation hybrids. We explore the\r\nconditions under which local adaptation can be maintained despite maladaptive gene flow\r\nand quantify the relative contributions of viability and sexual selection to genome-wide\r\nbarriers to gene flow.\r\nThe next two chapters of the thesis focus on a hybrid zone of Antirrhinum majus that\r\nconsist of two subspecies- the magenta flowered A. m. pseudomajus and the yellow\r\nflowered A.m. striatum. Previous studies have suggested that flower colour is target of\r\npollinator mediated selection and is influenced only by few genes. While these regions\r\nshow high genetic differentiation between the subspecies, the rest of the genome is seen\r\nto be well mixed. Chapter 4 examines the effects of heterogeneous population density\r\nand leptokurtic dispersal on isolation by distance and the distribution of heterozygosity\r\nby focusing on non-flower colour markers.\r\nChapter 5 analyses cline shapes and associations among 6 focal flower colour markers to\r\nunderstand how selection and dispersal maintain this hybrid zone. We see sharp coincident\r\nstepped clines at all loci and positive associations throughout the hybrid zone, contrary to\r\nthe expected patterns from diffusive gene flow. With a novel scheme of inferring dispersal\r\ncombined with multilocus simulations, we show that stepped clines do not reflect genetic\r\nbarriers to gene flow, but are rather a result of long-distance migration. This framework\r\nallows us to get realistic estimates gene flow and selection and shows how traditional cline\r\nanalysis may lead to inaccurate conclusions when assumptions of the theory are not met.\r\nOverall, this thesis investigates how different features of population structure leave\r\ndetectable signatures in genetic variation, namely in patterns of isolation by distance,\r\nlinkage disequilibrium and genetic divergence. It also highlights how effective migration\r\nrates provide useful way of analysing polygenic architectures and shed new light into\r\nhybrid zones. In doing so, I identify scenarios when simple models become insufficient\r\nand suggest possibe directions by combining genetic data with simulations.","lang":"eng"}],"oa_version":"Published Version","file":[{"success":1,"date_updated":"2024-11-07T10:59:29Z","file_size":37019760,"file_name":"PhD_Thesis__Parvathy_071124_PDFA.pdf","checksum":"c32cf7bc75748d9c551d8eb70178bbec","content_type":"application/pdf","date_created":"2024-11-07T10:59:29Z","relation":"main_file","access_level":"open_access","creator":"psurendr","file_id":"18519"},{"file_id":"18520","creator":"psurendr","access_level":"closed","relation":"source_file","date_created":"2024-11-07T10:59:42Z","content_type":"application/zip","checksum":"4417e02d54084d89e75734e18caaa96d","file_name":"PhD Thesis- Parvathy_071124.zip","file_size":41198857,"date_updated":"2024-11-07T10:59:42Z"}],"project":[{"_id":"05959E1C-7A3F-11EA-A408-12923DDC885E","name":"Snapdragon Speciation","grant_number":"P32166"},{"name":"Understanding the evolution of continuous genomes","_id":"bd6958e0-d553-11ed-ba76-86eba6a76c00","grant_number":"101055327"}],"article_processing_charge":"No","OA_place":"publisher","publication_status":"published","language":[{"iso":"eng"}],"author":[{"id":"455235B8-F248-11E8-B48F-1D18A9856A87","full_name":"Surendranadh, Parvathy","first_name":"Parvathy","orcid":"0000-0001-6395-386X","last_name":"Surendranadh"}],"status":"public","supervisor":[{"orcid":"0000-0002-8548-5240","last_name":"Barton","first_name":"Nicholas H","full_name":"Barton, Nicholas H","id":"4880FE40-F248-11E8-B48F-1D18A9856A87"}],"page":"219","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode","image":"/images/cc_by_nc_sa.png","short":"CC BY-NC-SA (4.0)","name":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)"},"title":"Effect of population structure on neutral genetic variation and barriers to gene exchange","license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","OA_type":"gold","has_accepted_license":"1","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","date_created":"2024-11-06T21:25:37Z","ddc":["576"],"corr_author":"1"},{"language":[{"iso":"eng"}],"author":[{"id":"3B12E2E6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3616-8580","last_name":"Datler","first_name":"Julia","full_name":"Datler, Julia"},{"full_name":"Hansen, Jesse","first_name":"Jesse","orcid":"0000-0001-7967-2085","last_name":"Hansen","id":"1063c618-6f9b-11ec-9123-f912fccded63"},{"id":"3A18A7B8-F248-11E8-B48F-1D18A9856A87","last_name":"Thader","full_name":"Thader, Andreas","first_name":"Andreas"},{"id":"45BF87EE-F248-11E8-B48F-1D18A9856A87","last_name":"Schlögl","orcid":"0000-0002-5621-8100","full_name":"Schlögl, Alois","first_name":"Alois"},{"last_name":"Bauer","full_name":"Bauer, Lukas W","first_name":"Lukas W","id":"0c894dcf-897b-11ed-a09c-8186353224b0"},{"last_name":"Hodirnau","orcid":"0000-0003-3904-947X","first_name":"Victor-Valentin","full_name":"Hodirnau, Victor-Valentin","id":"3661B498-F248-11E8-B48F-1D18A9856A87"},{"id":"48AD8942-F248-11E8-B48F-1D18A9856A87","last_name":"Schur","orcid":"0000-0003-4790-8078","first_name":"Florian KM","full_name":"Schur, Florian KM"}],"APC_amount":"11700 EUR","external_id":{"pmid":["38316877"],"isi":["001158144600002"]},"intvolume":" 31","status":"public","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"page":"1114-1123","quality_controlled":"1","title":"Multi-modal cryo-EM reveals trimers of protein A10 to form the palisade layer in poxvirus cores","has_accepted_license":"1","OA_type":"hybrid","volume":31,"related_material":{"link":[{"url":"https://ista.ac.at/en/news/down-to-the-core-of-poxviruses/","description":"News on ISTA Website","relation":"press_release"}],"record":[{"relation":"dissertation_contains","status":"public","id":"18766"}]},"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","keyword":["Molecular Biology","Structural Biology"],"pmid":1,"corr_author":"1","article_type":"original","date_created":"2024-02-12T09:59:45Z","ddc":["570"],"oa":1,"citation":{"mla":"Datler, Julia, et al. “Multi-Modal Cryo-EM Reveals Trimers of Protein A10 to Form the Palisade Layer in Poxvirus Cores.” Nature Structural & Molecular Biology, vol. 31, Springer Nature, 2024, pp. 1114–23, doi:10.1038/s41594-023-01201-6.","ama":"Datler J, Hansen J, Thader A, et al.

Hence, which proteins constitute which layers of the core, such as the palisade layer and the inner core wall, has remained enigmatic. Here we show, using a multi-modal cryo-electron microscopy (cryo-EM) approach in combination with AlphaFold molecular modeling, that trimers formed by the cleavage product of VACV protein A10 are the key component of the palisade layer.

In this study, we present a gatemon fabricated in planar Germanium. We induce superconductivity in a two-dimensional hole gas by evaporating aluminum atop a thin spacer, which separates the superconductor from the Ge quantum well. The Josephson junction is then integrated into an Xmon circuit and capacitively coupled to a transmission line resonator. We showcase the qubit tunability in a broad frequency range with resonator and two-tone spectroscopy. Time-domain characterizations reveal energy relaxation and coherence times up to 75 ns. Our results, combined with the recent advances in the spin qubit field, pave the way towards novel hybrid and protected qubits in a group IV, CMOS-compatible material."}],"year":"2024","date_updated":"2026-04-07T13:01:55Z","arxiv":1,"isi":1,"month":"07","date_published":"2024-07-30T00:00:00Z","publisher":"Springer Nature","quality_controlled":"1","title":"A gate tunable transmon qubit in planar Ge","DOAJ_listed":"1","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"intvolume":" 15","status":"public","language":[{"iso":"eng"}],"APC_amount":"6828 EUR","external_id":{"pmid":["39080279"],"arxiv":["2403.16774"],"isi":["001281271000022"]},"author":[{"id":"71616374-A8E9-11E9-A7CA-09ECE5697425","last_name":"Sagi","first_name":"Oliver","full_name":"Sagi, Oliver"},{"id":"1F2B21A2-F6E7-11E9-9B82-F7DBE5697425","orcid":"0000-0002-2968-611X","last_name":"Crippa","first_name":"Alessandro","full_name":"Crippa, Alessandro"},{"id":"C0BB2FAC-D767-11E9-B658-BC13E6697425","last_name":"Valentini","full_name":"Valentini, Marco","first_name":"Marco"},{"full_name":"Janik, Marian","first_name":"Marian","orcid":"0009-0003-9037-8831","last_name":"Janik","id":"396A1950-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Levon","full_name":"Baghumyan, Levon","last_name":"Baghumyan","id":"7aa1f788-b527-11ee-aa9e-e6111a79e0c7"},{"id":"298cf6f3-1ff6-11ee-9fa6-d94cfa0b3352","first_name":"Giorgio","full_name":"Fabris, Giorgio","last_name":"Fabris"},{"id":"84b9700b-15b2-11ec-abd3-831089e67615","first_name":"Lucky","full_name":"Kapoor, Lucky","orcid":"0000-0001-8319-2148","last_name":"Kapoor"},{"orcid":"0000-0001-6937-5773","last_name":"Hassani","first_name":"Farid","full_name":"Hassani, Farid","id":"2AED110C-F248-11E8-B48F-1D18A9856A87"},{"id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","full_name":"Fink, Johannes M","first_name":"Johannes M","last_name":"Fink","orcid":"0000-0001-8112-028X"},{"first_name":"Stefano","full_name":"Calcaterra, Stefano","last_name":"Calcaterra"},{"last_name":"Chrastina","full_name":"Chrastina, Daniel","first_name":"Daniel"},{"first_name":"Giovanni","full_name":"Isella, Giovanni","last_name":"Isella"},{"id":"38DB5788-F248-11E8-B48F-1D18A9856A87","full_name":"Katsaros, Georgios","first_name":"Georgios","orcid":"0000-0001-8342-202X","last_name":"Katsaros"}],"corr_author":"1","article_type":"original","date_created":"2024-07-04T11:40:45Z","ddc":["530"],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","article_number":"6400","pmid":1,"volume":15,"related_material":{"link":[{"url":"https://doi.org/10.1038/s41467-024-53910-1","relation":"erratum"}],"record":[{"id":"17196","relation":"research_data","status":"public"},{"status":"public","relation":"dissertation_contains","id":"18076"}]},"has_accepted_license":"1","OA_type":"gold"},{"publication":"Conference on Lasers and Electro-Optics","_id":"21605","day":"01","doi":"10.1364/cleo_fs.2024.fw3q.6","publication_identifier":{"eisbn":["9781957171395"]},"type":"conference","citation":{"apa":"Horodynski, M., Roques-Carmes, C., Salamin, Y., Choi, S., Sloan, J., Luo, D., & Soljačić, M.

This composition is believed\r\nto enable extremophile archaea to survive harsh environments. Here, through the creation of a\r\nminimal computational model for bolalipid membranes, we discover trade-offs when forming\r\nmembranes using lipids of a single type. Similar to living archaea, we can tune the stiffness of\r\nbolalipid molecules. We find that membranes made out of flexible bolalipid molecules resemble\r\nbilayer membranes as they can adopt U-shaped conformations to enable higher curvatures.\r\nConversely, rigid bolalipid molecules, like those found in archaea at higher temperatures,\r\npreferentially take on a straight conformation to self-assemble into liquid membranes that are\r\nstable, stiff, prone to pore formation, and which tear during membrane reshaping. Strikingly,\r\nhowever, our analysis reveals that it is possible to achieve the best of both worlds – membranes\r\nthat are fluid, stable at high temperatures and flexible enough to be reshaped without leaking –\r\nthrough the inclusion of a small fraction of bilayer lipids into a bolalipid membrane. Additionally,\r\nthe curvature-dependent softening of bolalipid membranes made of lipids with tension-sensitive\r\nconformation can also enable high rigidity at low curvatures while softening at high curvatures,\r\nmaking the membrane effectively a plastic material. Taken together, our study compares the\r\ndifferent membrane designs across the tree of life and indicates how combining lipids can be\r\nused to resolve trade-offs when generating membranes for (bio)technological applications.\r\n","lang":"eng"}],"date_published":"2024-12-17T00:00:00Z","publisher":"Institute of Science and Technology Austria","title":"Archaeal membranes : In silico modelling and design","license":"https://creativecommons.org/licenses/by-sa/4.0/","page":"57","tmp":{"short":"CC BY-SA (4.0)","name":"Creative Commons Attribution-ShareAlike 4.0 International Public License (CC BY-SA 4.0)","image":"/images/cc_by_sa.png","legal_code_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode"},"status":"public","supervisor":[{"id":"bf63d406-f056-11eb-b41d-f263a6566d8b","full_name":"Šarić, Anđela","first_name":"Anđela","last_name":"Šarić","orcid":"0000-0002-7854-2139"}],"language":[{"iso":"eng"}],"author":[{"id":"4f2d02dd-47a9-11ec-ad10-82820ed3f501","last_name":"Santana de Freitas Amaral","first_name":"Miguel","full_name":"Santana de Freitas Amaral, Miguel"}],"date_created":"2024-12-16T10:53:39Z","ddc":["572","530"],"corr_author":"1","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","related_material":{"record":[{"relation":"part_of_dissertation","status":"public","id":"18670"}]},"has_accepted_license":"1"},{"day":"16","_id":"17183","publication":"PRX Quantum","issue":"1","acknowledged_ssus":[{"_id":"M-Shop"}],"file_date_updated":"2024-06-28T12:04:43Z","type":"journal_article","department":[{"_id":"JoFi"},{"_id":"AnHi"}],"citation":{"chicago":"Sett, Riya, Farid Hassani, Duc T Phan, Shabir Barzanjeh, Andras Vukics, and Johannes M Fink. “Emergent Macroscopic Bistability Induced by a Single Superconducting Qubit.” PRX Quantum.

However, the predicted scaling from a microscopic behavior—dominated by quantum fluctuations—to a macroscopic one—characterized by stable phases—and the associated exponents and phase diagram have not been observed so far. In this work we couple a single transmon qubit with a fixed coupling strength 𝑔 to a superconducting cavity that is in situ bandwidth 𝜅 tunable to controllably approach this thermodynamic limit. Even though the system remains microscopic, we observe its behavior becoming increasingly macroscopic as a function of 𝑔/𝜅. For the highest realized 𝑔/𝜅 of approximately 287, the system switches with a characteristic timescale as long as 6 s between a bright coherent state with approximately 8×103 intracavity photons and the vacuum state. This exceeds the microscopic timescales by 6 orders of magnitude and approaches the perfect hysteresis expected between two macroscopic attractors in the thermodynamic limit. These findings and interpretation are qualitatively supported by neoclassical theory and large-scale quantum-jump Monte Carlo simulations. Besides shedding more light on driven-dissipative physics in the limit of strong light-matter coupling, this system might also find applications in quantum sensing and metrology."}],"year":"2024","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"DOAJ_listed":"1","title":"Emergent macroscopic bistability induced by a single superconducting qubit","quality_controlled":"1","external_id":{"isi":["001171652500001"],"arxiv":["2210.14182"]},"author":[{"id":"2E6D040E-F248-11E8-B48F-1D18A9856A87","full_name":"Sett, Riya","first_name":"Riya","last_name":"Sett","orcid":"0000-0001-7641-8348"},{"id":"2AED110C-F248-11E8-B48F-1D18A9856A87","full_name":"Hassani, Farid","first_name":"Farid","last_name":"Hassani","orcid":"0000-0001-6937-5773"},{"last_name":"Phan","first_name":"Duc T","full_name":"Phan, Duc T","id":"29C8C0B4-F248-11E8-B48F-1D18A9856A87"},{"id":"2D25E1F6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0415-1423","last_name":"Barzanjeh","full_name":"Barzanjeh, Shabir","first_name":"Shabir"},{"first_name":"Andras","full_name":"Vukics, Andras","last_name":"Vukics"},{"id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","full_name":"Fink, Johannes M","first_name":"Johannes M","last_name":"Fink","orcid":"0000-0001-8112-028X"}],"APC_amount":"3782,54","language":[{"iso":"eng"}],"status":"public","intvolume":" 5","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_number":"010327","ddc":["530"],"date_created":"2024-06-27T10:58:06Z","article_type":"original","corr_author":"1","OA_type":"gold","has_accepted_license":"1","ec_funded":1,"related_material":{"record":[{"id":"18978","relation":"research_data","status":"public"},{"status":"public","relation":"dissertation_contains","id":"19533"}]},"volume":5},{"publisher":"Institute of Science and Technology Austria","date_published":"2024-09-10T00:00:00Z","abstract":[{"text":"This work can be broadly classified into the study of critical phenomena in a one dimensional\r\narray of Josephson junctions. While we study quantum criticality when the array is in thermal\r\nequilibrium at zero bias, the non-equilibrium study involves understanding the bistability of the\r\narray at a critical non-zero bias. This work furthers our knowledge in understanding quantum\r\ncritical behaviour at finite temperatures in a one dimensional Josephson array, while also\r\nestablishing relaxation behaviour dual to that observed in a single Josephson junction.\r\nChapter 1 briefly introduces the model to understand superconductor-insulator phase transition\r\nin a one dimensional Josephson array and points out the state of the field from where we\r\nstarted our zero-bias experiments. In this context it discusses the phase-charge duality observed\r\nin a Josephson array and its dual hysteretic behaviour to that of a single junction, setting the\r\nground for our non-equilibrium study of the array.\r\nChapter 2 shows the experimental setup and the chip layout of the device we measured.\r\nIn chapter 3 we show that, unlike the typical quantum-critical broadening scenario, in one dimensional Josephson arrays temperature dramatically shifts the critical region. This shift leads\r\nto a regime of superconductivity at high temperature, arising from the melted zero-temperature\r\ninsulator. Our results quantitatively explain the low-temperature onset of superconductivity in\r\nnominally insulating regimes, and the transition to the strongly insulating phase. We further\r\npresent, to our knowledge, the first understanding of the onset of anomalous-metallic resistance\r\nsaturation [30]. This work demonstrates a non-trivial interplay between thermal effects and\r\nquantum criticality. A practical consequence is that, counterintuitively, the coherence of\r\nhigh-impedance quantum circuits is expected to be stabilized by thermal fluctuations.\r\nIn chapter 4, we show relaxation oscillations in a current-biased one dimensional array of\r\nJosephson junctions. These oscillations are well described by a circuit model, dual to the\r\nordinary Josephson relaxation oscillations [72]. Injection locking these oscillations results in\r\ncurrent plateaux. The relaxation step is found to obey a characteristic self-consistent relation,\r\nsuggesting that it is governed by overheating effects.\r\nChapter 5 describes the various checks and analysis we performed to support our conclusions\r\nmade in chapters 3 and 4.\r\nFinally, chapter 6 describes the nanofabrication steps and the finite element electromagnetic\r\nsimulations we performed to fabricate our devices.","lang":"eng"}],"year":"2024","alternative_title":["ISTA Thesis"],"month":"09","date_updated":"2026-06-03T07:16:04Z","oa_version":"Published Version","file":[{"date_created":"2024-09-12T10:46:04Z","relation":"main_file","access_level":"open_access","creator":"smukhopa","embargo":"2025-03-13","file_id":"18059","date_updated":"2025-03-13T23:30:04Z","file_size":10297052,"file_name":"PhD_Thesis_Soham_Mukhopadhyay.pdf","checksum":"ed7763c3bbd59e1d7e1b664de3a26f3c","content_type":"application/pdf"},{"embargo_to":"open_access","file_size":29178634,"date_updated":"2025-03-13T23:30:04Z","content_type":"application/zip","file_name":"PhD_Thesis_Soham_Mukhopadhyay_source.zip","checksum":"e352667482701dd18a9a0e7418aef465","access_level":"closed","creator":"smukhopa","date_created":"2024-09-12T10:50:58Z","relation":"source_file","file_id":"18060"}],"OA_place":"publisher","publication_status":"published","article_processing_charge":"No","project":[{"_id":"0aa3608a-070f-11eb-9043-e9cd8a2bd931","name":"Cavity electromechanics across a quantum phase transition","grant_number":"P33692"}],"oa":1,"citation":{"short":"S.
