We systematically tested various experimental parameters such as the order of projections, different angular increments and the use of the Volta phase plate. We find that although any of the prominently used acquisition schemes is sufficient to obtain subnanometer resolution, dose-symmetric acquisition provides considerably better outcome.

We shall be concerned with some mathematical aspects of this complicated problem in many-body quantum mechanics. More specifically, we consider the dilute limit where the scattering length of the interaction potential, which is a measure for the effective range of the potential, is small compared to the average distance between the particles. We are interested in a setting with positive (i.e., non-zero) temperature. After giving a survey of the relevant literature in the field, we provide some facts and examples to set expectations for the two-dimensional system. The crucial difference to the three-dimensional system is that there is no Bose–Einstein condensate at positive temperature due to the Hohenberg–Mermin–Wagner theorem. However, it turns out that an asymptotic formula for the free energy holds similarly to the three-dimensional case.\r\nWe motivate this formula by considering a toy model with δ interaction potential. By restricting this model Hamiltonian to certain trial states with a quasi-condensate we obtain an upper bound for the free energy that still has the quasi-condensate fraction as a free parameter. When minimizing over the quasi-condensate fraction, we obtain the Berezinskii–Kosterlitz–Thouless critical temperature for superfluidity, which plays an important role in our rigorous contribution. The mathematically rigorous result that we prove concerns the specific free energy in the dilute limit. We give upper and lower bounds on the free energy in terms of the free energy of the non-interacting system and a correction term coming from the interaction. Both bounds match and thus we obtain the leading term of an asymptotic approximation in the dilute limit, provided the thermal wavelength of the particles is of the same order (or larger) than the average distance between the particles. The remarkable feature of this result is its generality: the correction term depends on the interaction potential only through its scattering length and it holds for all nonnegative interaction potentials with finite scattering length that are measurable. In particular, this allows to model an interaction of hard disks."}],"date_created":"2020-02-24T09:17:27Z","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","supervisor":[{"orcid":"0000-0002-6781-0521","first_name":"Robert","full_name":"Seiringer, Robert","last_name":"Seiringer","id":"4AFD0470-F248-11E8-B48F-1D18A9856A87"}],"publication_identifier":{"issn":["2663-337X"]},"publication_status":"published","alternative_title":["ISTA Thesis"],"corr_author":"1","_id":"7514","date_published":"2020-02-24T00:00:00Z","status":"public","file":[{"checksum":"b4de7579ddc1dbdd44ff3f17c48395f6","access_level":"open_access","content_type":"application/pdf","creator":"dernst","file_size":1563429,"date_created":"2020-02-24T09:15:06Z","relation":"main_file","date_updated":"2020-07-14T12:47:59Z","file_name":"thesis.pdf","file_id":"7515"},{"creator":"dernst","access_level":"closed","content_type":"application/x-zip-compressed","checksum":"ad7425867b52d7d9e72296e87bc9cb67","file_id":"7516","file_name":"thesis_source.zip","date_updated":"2020-07-14T12:47:59Z","date_created":"2020-02-24T09:15:16Z","relation":"source_file","file_size":2028038}],"oa":1,"article_processing_charge":"No","publisher":"Institute of Science and Technology Austria","ddc":["510"],"day":"24","author":[{"id":"30C4630A-F248-11E8-B48F-1D18A9856A87","last_name":"Mayer","full_name":"Mayer, Simon","first_name":"Simon"}],"has_accepted_license":"1","doi":"10.15479/AT:ISTA:7514","department":[{"_id":"RoSe"},{"_id":"GradSch"}],"related_material":{"record":[{"id":"7524","status":"public","relation":"part_of_dissertation"}]},"language":[{"iso":"eng"}],"file_date_updated":"2020-07-14T12:47:59Z","oa_version":"Published Version","ec_funded":1,"project":[{"call_identifier":"H2020","_id":"25C6DC12-B435-11E9-9278-68D0E5697425","grant_number":"694227","name":"Analysis of quantum many-body systems"}],"title":"The free energy of a dilute two-dimensional Bose gas","date_updated":"2026-04-08T07:25:40Z"},{"publication":"Communications Physics","type":"journal_article","year":"2020","quality_controlled":"1","citation":{"ista":"Senior JL, Gubaydullin A, Karimi B, Peltonen JT, Ankerhold J, Pekola JP. 2020.

Here we show that by integrating superconducting quantum bit coupled to two superconducting resonators at different frequencies, each resonator terminated (and thermally populated) by such a mesoscopic thin film metal island, one can experimentally observe magnetic flux-tunable photonic heat rectification between 0 and 10%."}],"date_created":"2020-02-26T13:51:14Z","month":"02","DOAJ_listed":"1","OA_place":"publisher","publication_identifier":{"issn":["2399-3650"]},"publication_status":"published","intvolume":"         3","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"user_id":"0043cee0-e5fc-11ee-9736-f83bc23afbf0","file":[{"file_size":1590721,"file_name":"s42005-020-0307-5.pdf","relation":"main_file","date_created":"2020-03-03T10:41:13Z","date_updated":"2020-07-14T12:48:00Z","file_id":"7559","checksum":"59255f51d9f113c40e3047e9ac83d367","creator":"dernst","access_level":"open_access","content_type":"application/pdf"},{"file_id":"7560","file_name":"42005_2020_307_MOESM1_ESM.pdf","date_updated":"2020-07-14T12:48:00Z","date_created":"2020-03-03T10:41:13Z","relation":"main_file","file_size":1007249,"creator":"dernst","content_type":"application/pdf","access_level":"open_access","checksum":"8325ae7b3c869d9aa6ed84823da4000a"}],"status":"public","issue":"1","oa":1,"article_processing_charge":"No","publisher":"Springer Nature","_id":"7530","date_published":"2020-02-25T00:00:00Z","extern":"1","file_date_updated":"2020-07-14T12:48:00Z","article_type":"original","article_number":"40","volume":3,"oa_version":"Published Version","title":"Heat rectification via a superconducting artificial atom","date_updated":"2024-10-15T12:36:24Z","ddc":["536"],"day":"25","author":[{"id":"5479D234-2D30-11EA-89CC-40953DDC885E","full_name":"Senior, Jorden L","last_name":"Senior","first_name":"Jorden L","orcid":"0000-0002-0672-9295"},{"first_name":"Azat","last_name":"Gubaydullin","full_name":"Gubaydullin, Azat"},{"last_name":"Karimi","full_name":"Karimi, Bayan","first_name":"Bayan"},{"full_name":"Peltonen, Joonas T.","last_name":"Peltonen","first_name":"Joonas T."},{"full_name":"Ankerhold, Joachim","last_name":"Ankerhold","first_name":"Joachim"},{"last_name":"Pekola","full_name":"Pekola, Jukka P.","first_name":"Jukka P."}],"has_accepted_license":"1","OA_type":"gold","doi":"10.1038/s42005-020-0307-5","language":[{"iso":"eng"}]},{"isi":1,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publication_identifier":{"issn":["2469-990X"]},"publication_status":"published","intvolume":"         5","month":"02","publication":"Physical Review Fluids","type":"journal_article","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1912.09270"}],"quality_controlled":"1","citation":{"apa":"Budanur, N.

Regarding the susceptibility of the laminar flow, two concepts have been particularly useful: the edge states and the minimal seeds. In this nonlinear picture of the transition, the basin boundary of turbulence is set by the edge state's stable manifold and this manifold comes closest in energy to the laminar equilibrium at the minimal seed. We begin this paper by presenting numerical experiments in which three-dimensional perturbations are too energetic to trigger turbulence in pipe flow but they do lead to turbulence when their amplitude is reduced. We show that this seemingly counterintuitive observation is in fact consistent with the fully nonlinear description of the transition mediated by the edge state. In order to understand the physical mechanisms behind this process, we measure the turbulent kinetic energy production and dissipation rates as a function of the radial coordinate. Our main observation is that the transition to turbulence relies on the energy amplification away from the wall, as opposed to the turbulence itself, whose energy is predominantly produced near the wall. This observation is further supported by the similar analyses on the minimal seeds and the edge states. Furthermore, we show that the time evolution of production-over-dissipation curves provides a clear distinction between the different initial amplification stages of the transition to turbulence from the minimal seed.","lang":"eng"}],"author":[{"first_name":"Nazmi B","orcid":"0000-0003-0423-5010","full_name":"Budanur, Nazmi B","last_name":"Budanur","id":"3EA1010E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Elena","full_name":"Marensi, Elena","last_name":"Marensi"},{"first_name":"Ashley P.","full_name":"Willis, Ashley P.","last_name":"Willis"},{"orcid":"0000-0003-2057-2754","first_name":"Björn","id":"3A374330-F248-11E8-B48F-1D18A9856A87","full_name":"Hof, Björn","last_name":"Hof"}],"day":"21","doi":"10.1103/physrevfluids.5.023903","scopus_import":"1","department":[{"_id":"BjHo"}],"language":[{"iso":"eng"}],"article_type":"original","oa_version":"Preprint","volume":5,"article_number":"023903","title":"Upper edge of chaos and the energetics of transition in pipe flow","date_updated":"2023-08-18T06:44:46Z","arxiv":1,"_id":"7534","date_published":"2020-02-21T00:00:00Z","external_id":{"isi":["000515065100001"],"arxiv":["1912.09270"]},"status":"public","article_processing_charge":"No","oa":1,"issue":"2","publisher":"American Physical Society"},{"date_published":"2020-02-01T00:00:00Z","_id":"7540","publisher":"Brill","article_processing_charge":"No","issue":"1-2","external_id":{"isi":["000525343300004"]},"status":"public","language":[{"iso":"eng"}],"department":[{"_id":"JiFr"}],"scopus_import":"1","doi":"10.1163/22238980-20191110","author":[{"full_name":"Verstraeten, Inge","last_name":"Verstraeten","id":"362BF7FE-F248-11E8-B48F-1D18A9856A87","first_name":"Inge","orcid":"0000-0001-7241-2328"},{"full_name":"Buyle, H.","last_name":"Buyle","first_name":"H."},{"last_name":"Werbrouck","full_name":"Werbrouck, S.","first_name":"S."},{"last_name":"Van Labeke","full_name":"Van Labeke, M.C.","first_name":"M.C."},{"last_name":"Geelen","full_name":"Geelen, D.","first_name":"D."}],"day":"01","date_updated":"2023-08-18T06:45:15Z","title":"In vitro shoot growth and adventitious rooting of Wikstroemia gemmata depends on light quality","oa_version":"None","volume":67,"article_type":"original","month":"02","date_created":"2020-02-28T09:18:01Z","abstract":[{"text":" In vitro propagation of the ornamentally interesting species Wikstroemia gemmata is limited by the recalcitrance to form adventitious roots.

Firstly, the effect of exogenous auxin was evaluated in both light and dark cultivated stem segments and also the sucrose-content of the medium was varied in order to determine better rooting conditions. Secondly, different spectral lights were evaluated and the effect on shoot growth and root induction demonstrated that the exact spectral composition of light is important for successful in vitro growth and development of Wikstroemia gemmata.

Here, combining top‐down nanofabrication and bottom‐up self‐assembly, the growth of Ge wires on prepatterned Si (001) substrates with controllable position, distance, length, and structure is reported. This is achieved by a novel growth process that uses a SiGe strain‐relaxation template and can be potentially generalized to other material combinations. Transport measurements show an electrically tunable spin–orbit coupling, with a spin–orbit length similar to that of III–V materials. Also, charge sensing between quantum dots in closely spaced wires is observed, which underlines their potential for the realization of advanced quantum devices.

The nematode Caenorhabditis elegans, owing to its compact translucent nervous system, is a powerful system in which to study conserved aspects of the development and plasticity of neuronal morphology. Here we focus on one pair of sensory neurons, termed URX, which the worm uses to sense and avoid high levels of environmental oxygen. Previous studies have reported that the URX neuron pair has variable branched endings at its dendritic sensory tip. By controlling oxygen levels and analyzing mutants, we found that these microtubule-rich branched endings grow over time as a consequence of neuronal activity in adulthood. We also find that the growth of these branches correlates with an increase in cellular sensitivity to particular ranges of oxygen that is observable in the behavior of older worms. Given the strengths of C. elegans as a model organism, URX may serve as a potent system for uncovering genes and mechanisms involved in activity-dependent morphological changes in neurons and possible adaptive changes in the aging nervous system.","lang":"eng"}],"quality_controlled":"1","year":"2020","citation":{"ista":"Cohn JA, Cebul ER, Valperga G, Brose L, de Bono M, Heiman MG, Pierce JT. 2020.

Genetic differences contribute to this variation, but the neural mechanisms are not understood. Here, we dissect natural variation in the behavioral flexibility of two Caenorhabditis elegans wild strains. In one strain, a memory of exposure to 21% O2 suppresses CO2-evoked locomotory arousal; in the other, CO2 evokes arousal regardless of previous O2 experience. We map that variation to a polymorphic dendritic scaffold protein, ARCP-1, expressed in sensory neurons. ARCP-1 binds the Ca2+-dependent phosphodiesterase PDE-1 and co-localizes PDE-1 with molecular sensors for CO2 at dendritic ends. Reducing ARCP-1 or PDE-1 activity promotes CO2 escape by altering neuropeptide expression in the BAG CO2 sensors. Variation in ARCP-1 alters behavioral plasticity in multiple paradigms. Our findings are reminiscent of genetic accommodation, an evolutionary process by which phenotypic flexibility in response to environmental variation is reset by genetic change.","lang":"eng"}],"date_created":"2020-02-28T10:43:39Z","citation":{"chicago":"Beets, Isabel, Gaotian Zhang, Lorenz A.

In particular, variable accretion rates, instabilities, and reverberation effects in the accretion disc of a supermassive black hole are expected to produce correlated flux variations in ultraviolet (UV) and optical bands. Recent work has further argued that binary quasars should exhibit strongly correlated UV and optical periodicities. Strong UV–optical correlations have indeed been established in small samples of (N ≲ 30) quasars with well-sampled light curves, and have extended the ‘bluer-when-brighter’ trend previously found within the optical bands. Here, we further test the nature of quasar variability by examining the observed-frame UV–optical correlations among bright quasars extracted from the Half Million Quasars (HMQ) catalogue. We identified a large sample of 1315 quasars in HMQ with overlapping UV and optical light curves from the Galaxy Evolution Explorer and the Catalina Real-time Transient Survey, respectively. We find that strong correlations exist in this much larger sample, but we rule out, at ∼95 per cent confidence, the simple hypothesis that the intrinsic UV and optical variations of all quasars are fully correlated.

In active galactic nuclei (AGN), binaries form and evolve efficiently by dynamical interactions and gaseous dissipation. Previous studies have suggested that binary black hole (BBH) mergers in AGN disks can contribute significantly to BBH mergers observed by GW interferometers. Here we examine the distribution of the effective spin parameter χeff of this GW source population. We extend our semi-analytical model of binary formation and evolution in AGN disks by following the evolution of the binary orbital angular momenta and black hole (BH) spins. BH spins change due to gas accretion and BH mergers, while the binary orbital angular momenta evolve due to gas accretion and binary-single interactions. We find that the distribution of χeff predicted by our AGN model is similar to the distribution observed during LIGO/Virgo O1 and O2. On the other hand, if radial migration of BHs is inefficient, χeff is skewed toward higher values compared with the observed distribution, because of the paucity of scattering events that would randomize spin directions relative to the orbital plane. We suggest that high binary masses and the positive correlation between binary mass and the standard deviation of χeff for chirp masses up to ≈20 M⊙, can be possible signatures for mergers originating in AGN disks. Finally, hierarchical mergers in AGN disks naturally produce properties of the recent GW event GW190412, including a low mass ratio, a high primary BH spin, and a significant spin component in the orbital plane."}],"citation":{"ieee":"H.

The primary and secondary BH are both inferred to fall inside the pair-instability (PI) mass gap. Here we propose that the formation of such binaries is possible through gas accretion onto the BH remnants of Population III (Pop~III) stars born in high-redshift (z>10) minihalos. Once the parent halo has grown to the atomic-cooling limit, even brief episodes of gas accretion in the dense central regions of the halo can increase the masses of Pop~III remnant BHs above the PI limit. Starting with a BBH with an initial mass of O(100) M⊙ we find that it would only need to spend about 100~Myr in the inner few pc of an atomic-cooling halo to accrete about 50~M⊙ of material and resemble a system similar to GW190521. The dynamical friction timescale for the binary to sink to the dense inner region of its parent halo is comparable or shorter than the accretion timescale required to increase their mass above the PI limit. Once in the core of the halo, the binary can enter a phase of hyper-Eddington accretion, where it would only take a few thousand years to exceed the PI limit through accretion. Even more massive BBHs could form through this channel, and be detectable by detectors with improved low-frequency sensitivity. Single Pop~III BH remnants would also grow through accretion and could later form binaries dynamically. As little as a few percent of Pop~III BH remnants may be sufficient to match the rate of massive BBH mergers inferred from GW190521 of 0.13+0.3−0.11Gpc−3yr−1."}],"date_created":"2024-09-05T09:50:29Z","quality_controlled":"1","year":"2020","citation":{"ama":"Safarzadeh M, Haiman Z.

Here we examine whether accretion on the protostellar core in this cloud is sufficiently rapid, in the face of the radiation feedback, to produce a SMS. We perform one-dimensional radiation-hydrodynamical simulations of the hot collapsing cloud with non-equilibrium chemical reactions directly adopting the cloud properties from Wise et al. (2019) as an initial condition. We find that the stellar Lyman-Werner (LW) radiation from the SMS dissociates H2 in the inner regions of the gas flow, increasing gas temperature and thermal pressure, and temporarily stopping the accretion. However, this negative feedback ceases when the self-gravity and inward ram pressure force on larger scales push the gas inward. The central protostar is unable to expand an HII region due to the high density, and grows to a mass of ≳105M⊙.

These events involve the coalescence of supermassive black holes in the mass range 105M⊙≲M≲107M⊙ with companion BHs of much lower masses. A subset of E/IMRIs are expected to occur in the accretion discs of active galactic nuclei (AGN), where torques exerted by the disc can interfere with the inspiral and cause a phase shift in the GW waveform. Here we use a suite of two-dimensional hydrodynamical simulations with the moving-mesh code DISCO to present a systematic study of disc torques. We measure torques on an inspiraling BH and compute the corresponding waveform deviations as a function of the binary mass ratio q≡M2/M1, the disc viscosity (α), and gas temperature (or equivalently Mach number; M). We find that the absolute value of the gas torques is within an order of magnitude of previously determined planetary migration torques, but their precise value and sign depends non-trivially on the combination of these parameters. The gas imprint is detectable by LISA for binaries embedded in AGN discs with surface densities above Σ0≥104−6gcm−2, depending on q, α and M. Deviations are most pronounced in discs with higher viscosities, and for E/IMRIs detected at frequencies where LISA is most sensitive. Torques in colder discs exhibit a noticeable dependence on the GW-driven inspiral rate as well as strong fluctuations at late stages of the inspiral. Our results further suggest that LISA may be able to place constraints on AGN disc parameters and the physics of disc-satellite interaction.","lang":"eng"}],"year":"2020","quality_controlled":"1","citation":{"ieee":"A.

Our method takes dark matter halo merger trees (including three-dimensional spatial information) from cosmological N-body simulations as input and applies analytic prescriptions to compute both the Population III and metal-enriched star formation histories. We have developed a novel method to accurately compute the major feedback processes affecting Population III star formation: H2 photodissociation from Lyman–Werner (LW) radiation, suppression of star formation due to inhomogeneous reionization, and metal enrichment via supernova winds. Our method utilizes a grid-based approach relying on fast Fourier transforms to rapidly track the LW intensity, ionization fraction, and metallicity in three dimensions throughout the simulation box. We present simulations for a wide range of astrophysical model parameters from z ≈ 30 to 6. Initially long-range LW feedback and local metal enrichment and reionization feedback dominate. However, for z ≲ 15 we find that the star formation rate density (SFRD) of Population III stars is impacted by the combination of external metal enrichment (metals from one halo polluting other pristine halos) and inhomogeneous reionization. We find that the interplay of these processes is particularly important for the Population III SFRD at z ≲ 10. Reionization feedback delays star formation long enough for metal bubbles to reach halos that would otherwise form Population III stars. Including these effects can lead to more than an order-of-magnitude decrease in the Population III SFRD at z = 6 compared to LW feedback alone."}],"year":"2020","quality_controlled":"1","citation":{"chicago":"Visbal, Eli, Greg L.
