However, switching AFM domains is challenging, as magnetic fields do not couple to the bulk antiferromagnetic order parameter. Here we show that magnetic-field-driven switching of AFM domains can in many cases be enabled by a generic reduction of magnetic exchange at surfaces. We use statistical mechanics and Monte Carlo simulations to demonstrate that an inequivalence in magnetic exchange between top and bottom surface moments, combined with the enhanced magnetic susceptibility of surface spins, can enable deterministic selection of antiferromagnetic domains depending on the magnetic-field ramping direction. We further show that this mechanism provides a natural interpretation for experimental observations of hysteresis in magneto-optical response of the van der Waals AFM $\\mathrm{MnBi_2Te_4}$. Our findings highlight the critical role of surface spins in responses of antiferromagnets to magnetic fields. Furthermore, our results suggest that antiferromagnetic domain selection via purely magnetic means may be a more common and experimentally accessible phenomenon than previously assumed.","lang":"eng"}],"publication_status":"submitted","oa_version":"Preprint","type":"preprint","year":"2026"},{"abstract":[{"text":"Three-dimensional (3D) crystals offer a route to scaling up trapped-ion systems for quantum sensing and quantum simulation applications; however, engineering coherent spin-motion couplings and effective spin-spin interactions in large crystals poses technical challenges associated with decoherence and prolonged timescales to generate appreciable entanglement. Here, we explore the possibility of speeding up these interactions in 3D crystals via parametric amplification. For this purpose, we derive a general Hamiltonian for the parametric amplification of spin-motion coupling that is broadly applicable to normal modes with motion transverse to or along the spatial extent of the crystal. Unlike in lower-dimensional crystals, we find that the ability to faithfully (uniformly) amplify the spin-spin interactions in 3D crystals depends on the physical implementation of the spin-motion coupling. We consider the light-shift gate, and the so-called phase-insensitive and phase-sensitive Mølmer-Sørensen (MS) gates, and we find that only the phase-sensitive MS gate can be faithfully amplified in general 3D crystals. We discuss a situation where nonuniform amplification can be advantageous. We also reconsider the effect of counter-rotating terms on parametric amplification and find that they are not as detrimental as previous studies suggest.","lang":"eng"}],"article_type":"original","oa_version":"Published Version","type":"journal_article","author":[{"orcid":"0000-0002-1965-4309","full_name":"Hawaldar, Samarth","last_name":"Hawaldar","first_name":"Samarth","id":"221708e1-1ff6-11ee-9fa6-85146607433e"},{"last_name":"Nikhil","first_name":"N.","full_name":"Nikhil, N."},{"last_name":"Rey","first_name":"Ana Maria","full_name":"Rey, Ana Maria"},{"last_name":"Bollinger","first_name":"John J.","full_name":"Bollinger, John J."},{"last_name":"Shankar","first_name":"Athreya","full_name":"Shankar, Athreya"}],"status":"public","date_created":"2026-03-15T23:01:35Z","_id":"21449","title":"Parametric amplification of spin-motion coupling in three-dimensional trapped-ion crystals","PlanS_conform":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2026-04-14T09:04:08Z","project":[{"grant_number":"F07105","name":"QUANTUM INFORMATION SYSTEMS BEYOND CLASSICAL CAPABILITIES / P5- Integration of Superconducting Quantum Circuits","_id":"bdb108fd-d553-11ed-ba76-83dc74a9864f"}],"citation":{"ama":"Hawaldar S, Nikhil N, Rey AM, Bollinger JJ, Shankar A.

A cocoon of dense excited gas is emerging as a key component to explain the most striking properties of LRDs, such as strong Balmer breaks and Balmer absorption, as well as the weak IR emission. To dissect the structure of LRDs, we analyzed new deep JWST/NIRSpec PRISM and G395H spectra of FRESCO-GN-9771, one of the most luminous known LRDs at z = 5.5. These spectra reveal a strong Balmer break, broad Balmer lines, and very narrow [O III] emission. We revealed a forest of optical [Fe II] lines, which we argue are emerging from a dense (nH = 109 − 10 cm−3) warm layer with electron temperature Te ≈ 7000 K. The broad wings of Hα and Hβ have an exponential profile due to electron scattering in this same layer. The high Hα : Hβ : Hγ flux ratio of ≈10.4 : 1 : 0.14 is an indicator of collisional excitation and resonant scattering dominating the Balmer line emission. A narrow Hγ component, unseen in the other two Balmer lines due to outshining by the broad components, could trace the ISM of a normal host galaxy with a star formation rate of ∼5 M⊙ yr−1. The warm layer is mostly opaque to Balmer transitions, producing a characteristic P Cygni profile in the line centers suggesting outflowing motions. This same layer is responsible for shaping the Balmer break. The broadband spectrum can be reasonably matched by a simple photoionized slab model that dominates the λ > 1500 Å continuum and a low-mass (∼108 M⊙) galaxy that could explain the narrow [O III], with only a subdominant contribution to the UV continuum. Our findings indicate that Balmer lines are not directly tracing the gas kinematics near the SMBH and that the BH mass scale is likely much lower than virial indicators suggest.","lang":"eng"}],"article_type":"original","type":"journal_article","oa_version":"Published Version","author":[{"orcid":"0000-0001-5586-6950","full_name":"Torralba Torregrosa, Alberto","id":"018f0249-0e87-11f0-b167-cbce08fbd541","last_name":"Torralba Torregrosa","first_name":"Alberto"},{"orcid":"0000-0003-2871-127X","full_name":"Matthee, Jorryt J","last_name":"Matthee","first_name":"Jorryt J","id":"7439a258-f3c0-11ec-9501-9df22fe06720"},{"last_name":"Pezzulli","first_name":"Gabriele","full_name":"Pezzulli, Gabriele"},{"full_name":"Naidu, Rohan P.","last_name":"Naidu","first_name":"Rohan P."},{"last_name":"Ishikawa","first_name":"Yuzo","full_name":"Ishikawa, Yuzo"},{"last_name":"Brammer","first_name":"Gabriel B.","full_name":"Brammer, Gabriel B."},{"last_name":"Chang","first_name":"Seok Jun","full_name":"Chang, Seok Jun"},{"first_name":"John","last_name":"Chisholm","full_name":"Chisholm, John"},{"full_name":"De Graaff, Anna","last_name":"De Graaff","first_name":"Anna"},{"first_name":"Francesco","last_name":"D’Eugenio","full_name":"D’Eugenio, Francesco"},{"last_name":"Di Cesare","first_name":"Claudia","id":"2d002343-372f-11ef-98ec-a164d20427cb","full_name":"Di Cesare, Claudia"},{"last_name":"Eilers","first_name":"Anna Christina","full_name":"Eilers, Anna Christina"},{"full_name":"Greene, Jenny E.","first_name":"Jenny E.","last_name":"Greene"},{"full_name":"Gronke, Max","first_name":"Max","last_name":"Gronke"},{"full_name":"Iani, Edoardo","orcid":"0000-0001-8386-3546","last_name":"Iani","first_name":"Edoardo","id":"4053390a-6b68-11ef-9828-a3b8adef8d0a"},{"full_name":"Kokorev, Vasily","last_name":"Kokorev","first_name":"Vasily"},{"first_name":"Gauri","last_name":"Kotiwale","id":"1438afc8-1ff6-11ee-9fa6-cd4a75d66875","full_name":"Kotiwale, Gauri"},{"full_name":"Kramarenko, Ivan","orcid":"0000-0001-5346-6048","first_name":"Ivan","last_name":"Kramarenko","id":"9a9394cb-3200-11ee-973b-f5ba2a8b16e4"},{"full_name":"Ma, Yilun","last_name":"Ma","first_name":"Yilun"},{"full_name":"Mascia, Sara","last_name":"Mascia","first_name":"Sara","id":"edaf889c-c7cd-11ef-ab1b-bb28c431bd29"},{"full_name":"Navarrete, Benjamín","id":"aa14a535-50c9-11ef-b52e-e0c373d10148","first_name":"Benjamín","last_name":"Navarrete"},{"first_name":"Erica","last_name":"Nelson","full_name":"Nelson, Erica"},{"full_name":"Oesch, Pascal","first_name":"Pascal","last_name":"Oesch"},{"last_name":"Simcoe","first_name":"Robert A.","full_name":"Simcoe, Robert A."},{"last_name":"Wuyts","first_name":"Stijn","full_name":"Wuyts, Stijn"}],"date_created":"2026-03-15T23:01:36Z","status":"public","_id":"21451","title":"The warm outer layer of a little red dot as the source of [Fe ii] and collisional Balmer lines with scattering wings","language":[{"iso":"eng"}],"OA_type":"diamond","OA_place":"publisher","publication_identifier":{"issn":["0004-6361"],"eissn":["1432-0746"]},"acknowledgement":"We thank the scientific referee for useful and constructive comments.

With JWST, the SFMS can now be investigated at high redshifts down to masses of ∼106 M⊙, using sensitive star formation rate tracers such as the Hα emission, which allow us to probe the variability in the star formation histories. We present inferences of the SFMS based on 316 Hα-selected galaxies at z ∼ 4 − 5 with log(M★/M⊙) = 6.4 − 10.6. These galaxies were identified behind the Abell 2744 lensing cluster with NIRCam grism spectroscopy from the survey All the Little Things (ALT). At face value, our data suggest a shallow slope in the SFMS (SFR ∝ M★α, with α = 0.45). After we corrected this for the Hα-flux limited nature of our survey using a Bayesian framework, the slope steepened to α = 0.59+0.10−0.09, whereas current data on their own are inconclusive on the mass dependence of the scatter. These slopes differ significantly from the slope of ∼1 that is expected from the observed evolution of the galaxy stellar mass function and from simulations. When we fixed the slope to α = 1, we found evidence for a decreasing intrinsic scatter with stellar mass (from ∼0.5 dex at M★ = 108 M⊙ to 0.4 dex at M★ = 1010 M⊙). This difference might be explained by a (combination of) luminosity-dependent SFR(Hα) calibration, a population of (mini)-quenched low-mass galaxies, or underestimated dust attenuation in high-mass galaxies. Future deep observations with different facilities can quantify these processes, which will enable us to achieve better insights into the variability of the star formation histories."}],"title":"The slope and scatter of the star-forming main sequence at z ∼ 5: Reconciling observations with simulations","_id":"21452","author":[{"full_name":"Di Cesare, Claudia","first_name":"Claudia","last_name":"Di Cesare","id":"2d002343-372f-11ef-98ec-a164d20427cb"},{"orcid":"0000-0003-2871-127X","full_name":"Matthee, Jorryt J","id":"7439a258-f3c0-11ec-9501-9df22fe06720","first_name":"Jorryt J","last_name":"Matthee"},{"last_name":"Naidu","first_name":"Rohan P.","full_name":"Naidu, Rohan P."},{"full_name":"Torralba, Alberto","last_name":"Torralba","first_name":"Alberto"},{"last_name":"Kotiwale","first_name":"Gauri","id":"1438afc8-1ff6-11ee-9fa6-cd4a75d66875","full_name":"Kotiwale, Gauri"},{"id":"9a9394cb-3200-11ee-973b-f5ba2a8b16e4","last_name":"Kramarenko","first_name":"Ivan","full_name":"Kramarenko, Ivan","orcid":"0000-0001-5346-6048"},{"full_name":"Blaizot, Jeremy","first_name":"Jeremy","last_name":"Blaizot"},{"last_name":"Rosdahl","first_name":"Joakim","full_name":"Rosdahl, Joakim"},{"full_name":"Leja, Joel","first_name":"Joel","last_name":"Leja"},{"id":"4053390a-6b68-11ef-9828-a3b8adef8d0a","last_name":"Iani","first_name":"Edoardo","orcid":"0000-0001-8386-3546","full_name":"Iani, Edoardo"},{"first_name":"Angela","last_name":"Adamo","full_name":"Adamo, Angela"},{"first_name":"Alba","last_name":"Covelo-Paz","full_name":"Covelo-Paz, Alba"},{"full_name":"Furtak, Lukas J.","last_name":"Furtak","first_name":"Lukas J."},{"first_name":"Kasper E.","last_name":"Heintz","full_name":"Heintz, Kasper E."},{"id":"edaf889c-c7cd-11ef-ab1b-bb28c431bd29","first_name":"Sara","last_name":"Mascia","full_name":"Mascia, Sara"},{"id":"aa14a535-50c9-11ef-b52e-e0c373d10148","first_name":"Benjamín","last_name":"Navarrete","full_name":"Navarrete, Benjamín"},{"last_name":"Oesch","first_name":"Pascal A.","full_name":"Oesch, Pascal A."},{"last_name":"Romano","first_name":"Michael","full_name":"Romano, Michael"},{"full_name":"Shivaei, Irene","first_name":"Irene","last_name":"Shivaei"},{"first_name":"Sandro","last_name":"Tacchella","full_name":"Tacchella, Sandro"}],"status":"public","date_created":"2026-03-15T23:01:36Z","language":[{"iso":"eng"}],"OA_type":"diamond","OA_place":"publisher","acknowledgement":"We thank the anonymous referee for the insightful comments that helped improving the manuscript.

Here, we study nonlinear THz-induced Kerr effect in a generic material LaAlO3. After detailed analysis of temporal oscillations of the Kerr signal, we identify an 𝐸𝑔 Raman mode at 1.1 THz excited through a two-photon process, while two additional peaks (0.86 and 0.36 THz) arise from phase matching of the near-infrared probe beam with co- and counterpropagating THz pump fields, mediated by off-resonant electronic hyperpolarizability.

Here, we introduce the R index—a metric that captures the intrinsic OAM content of any structured optical field, from pure Laguerre–Gaussian modes to arbitrary multi vortex superpositions. Not only does this metric quantify the total OAM, it also assesses field purity, providing insight into the fidelity and robustness of the OAM generation.

Whereas animal studies have offered cellular- and synaptic-level accounts of these effects, human neuroimaging studies show that exercise improves hippocampal-cortical connectivity at the macroscale level. However, the neurophysiological basis of exercise-induced effects on hippocampal-cortical circuits remains unknown. Experimental evidence supports the idea that hippocampal sharp wave-ripples (SWR) play a critical role in learning and memory. Coupling between SWRs in the hippocampus and neocortex may reflect modulations in inter-regional connectivity required by mnemonic processes. Here, we examine the hypothesis that exercise modulates hippocampal-cortical ripple dynamics in the human brain. We performed intracranial recordings in epilepsy patients undergoing pre-surgical evaluation, during awake resting state, before and after an exercise session. Exercise increased ripple rate in the hippocampus. Exercise also enhanced the coupling and phase-synchrony between cortical ripples in the limbic and the default mode (DM) cortical networks and hippocampal SWRs. Further, a higher heart rate during exercise, reflecting exercise intensity, was related to a subsequent increase in resting state ripples across specific cortical networks, including the DM network. These results offer the first direct evidence that a single exercise session elicits changes in ripple events, a well-established neurophysiological marker of mnemonic processing. The characterisation and anatomical distribution of the described modulation points to hippocampal ripples as a potential mechanism by which exercise elicits its reported short-term effects in cognition."}],"article_type":"original","oa_version":"Published Version","type":"journal_article","status":"public","date_created":"2026-03-22T23:04:34Z","author":[{"full_name":"Cardenas, Araceli R.","last_name":"Cardenas","first_name":"Araceli R."},{"full_name":"Ramirez Villegas, Juan F","id":"44B06F76-F248-11E8-B48F-1D18A9856A87","last_name":"Ramirez Villegas","first_name":"Juan F"},{"full_name":"Kovach, Christopher K.","first_name":"Christopher K.","last_name":"Kovach"},{"last_name":"Gander","first_name":"Phillip E.","full_name":"Gander, Phillip E."},{"full_name":"Cole, Rachel C.","last_name":"Cole","first_name":"Rachel C."},{"full_name":"Grossbach, Andrew J.","last_name":"Grossbach","first_name":"Andrew J."},{"last_name":"Kawasaki","first_name":"Hiroto","full_name":"Kawasaki, Hiroto"},{"full_name":"Greenlee, Jeremy D.W.","last_name":"Greenlee","first_name":"Jeremy D.W."},{"last_name":"Howard","first_name":"Matthew A.","full_name":"Howard, Matthew A."},{"last_name":"Nourski","first_name":"Kirill V.","full_name":"Nourski, Kirill V."},{"full_name":"Banks, Matthew I.","first_name":"Matthew I.","last_name":"Banks"},{"first_name":"Michelle W.","last_name":"Voss","full_name":"Voss, Michelle W."}],"_id":"21473","title":"Exercise enhances hippocampal-cortical ripple interactions in the human brain"},{"article_number":"090801","volume":136,"doi":"10.1103/rbg2-f61m","file":[{"date_created":"2026-03-23T15:35:27Z","checksum":"12b16ce2d49c62b2909da95121bfaadb","success":1,"relation":"main_file","creator":"dernst","access_level":"open_access","file_id":"21491","file_size":500041,"date_updated":"2026-03-23T15:35:27Z","content_type":"application/pdf","file_name":"2026_PhysicalReviewLetters_Votto.pdf"}],"day":"04","oa":1,"external_id":{"arxiv":["2507.12550"]},"publisher":"American Physical Society","month":"03","department":[{"_id":"MaSe"}],"has_accepted_license":"1","file_date_updated":"2026-03-23T15:35:27Z","date_published":"2026-03-04T00:00:00Z","article_processing_charge":"Yes (in subscription journal)","fulldoi":"https://doi.org/10.1103/rbg2-f61m","arxiv":1,"ddc":["530"],"tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"publication_status":"published","year":"2026","quality_controlled":"1","intvolume":"       136","OA_place":"publisher","OA_type":"hybrid","language":[{"iso":"eng"}],"publication":"Physical Review Letters","issue":"9","acknowledgement":"We acknowledge insightful discussions with Antoine Browaeys, Mari Carmen Bañuls, Soonwon Choi, Thierry Lahaye, Daniel Stilck-França, Georgios Styliaris, and Xavier Waintal.

The tensor optimization is carried out sequentially, similarly to the well-known density matrix renormalization group algorithm. Our approach is provably efficient under certain technical conditions expected to be met in short-range correlated states and in typical noisy experimental settings. Under the same conditions, we also provide an efficient scheme to estimate fidelities between the learned and the experimental states.

With the advent of JWST, we are now able to routinely observe Hα in galaxies at high redshift (z ≳ 3) and thus measure their star formation rates (SFRs). However, using classical SFR(Hα) calibrations to derive the SFRs leads to biased results because high-redshift galaxies are commonly characterized by low metallicities and bursty star formation histories, affecting the conversion factor between the Hα luminosity (LHα) and the SFR. We developed a set of new SFR(Hα) calibrations that allowed us to predict the SFRs of Hα-emitters at z ≳ 3 with very little error. We used the SPHINX cosmological simulations to select a sample of star-forming galaxies representative of the Hα-emitter population observed with JWST. We then derived linear corrections to the classical SFR(Hα) calibrations that took variations in the physical properties (e.g., stellar metallicities) among individual galaxies into account. We obtained two new SFR(Hα) calibrations that compared to the classical calibrations reduce the root mean squared error (RMSE) in the predicted SFRs by ΔRMSE ≈ 0.04 dex and ΔRMSE ≈ 0.06 dex, respectively. Using the recent JWST NIRCam/grism observations of Hα-emitters at z ∼ 6, we show that the new calibrations affect the high-redshift galaxy population statistics: (i) the estimated cosmic SFR density decreases by ΔρSFR ≈ 12%, and (ii) the observed slope of the star formation main sequence increases by Δ∂logSFR/∂logM★ = 0.08 ± 0.02.","lang":"eng"}],"project":[{"name":"Young galaxies as tracers and agents of cosmic reionization","_id":"bd9b2118-d553-11ed-ba76-db24564edfea","grant_number":"101076224"}],"DOAJ_listed":"1","citation":{"ama":"Kramarenko I, Rosdahl J, Blaizot J, Matthee JJ, Katz H, Di Cesare C.

Here, we show that specific but promiscuous short-range binding interactions make it possible to economically assemble linear filaments of user-defined length. Our approach leads to independent control over the mean and width of the filament size distribution and allows us to smoothly explore design trade-offs between assembly quality (spread in size) and cost (number of particle species). We employ a simple hierarchical assembly protocol to minimize assembly times and show that multiple stages of hierarchy make it possible to extend our approach to the assembly of higher-dimensional structures.

Of the many ways in which they influence natural phenomena, perhaps the most consequential is their capacity to transfer electrical charge during contact4,5,6,7,8,9,10—which occurs even between samples of the same oxide—yet the symmetry-breaking parameter that causes this remains unidentified11,12. Here we show that adventitious carbonaceous molecules adsorbed from the environment are the symmetry-breaking factor in same-material oxide contact electrification (CE). We use acoustic levitation to measure charge exchange between a sphere and a plate composed of identical amorphous silicon dioxide (SiO2). Although charging polarity is random for co-prepared samples, we control it with baking or plasma treatment. Observing the charge-exchange relaxation afterwards, we see dynamics over a timescale of hours and connect this directly to the presence of adventitious carbon with time-of-flight mass spectrometry, low-energy ion scattering and infrared spectroscopy. Going further, we confirm that adventitious carbon can even determine charge exchange among different oxides. Our results identify the symmetry-breaking parameter that causes insulating oxides to exchange charge in settings ranging from desert sands4 to volcanic plumes5,6, while simultaneously highlighting an overlooked factor in CE more broadly.","lang":"eng"}],"OA_type":"hybrid","OA_place":"publisher","language":[{"iso":"eng"}],"publication":"Nature","issue":"8106","ec_funded":1,"publication_identifier":{"issn":["0028-0836"],"eissn":["1476-4687"]},"acknowledgement":"This project has received support from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement no. 949120) and from the Marie Skłodowska-Curie programme (grant agreement no. 754411).

Many evaluated tools, especially ensemble frameworks, matched or exceeded star allele classifications (ROC‑AUC up to 0.85 for allele definitions, 0.95 in vitro; TPR up to 0.99 for exomes) and accurately predicted severe antidepressant adverse events for carriers of deleterious variants in CYP2C19 (OR 1.20–1.35).

In parallel, advances in nanophotonics have enabled wavefront control through metasurfaces, a capability that has transformed fields such as microscopy by allowing tailored control of optical propagation. This naturally raises the following question, which we address in this Perspective: can wavefront-control strategies be leveraged to improve scintillation-based imaging? To answer this question, we explore nanophotonic- and metasurface-enabled wavefront control in scintillators to mitigate image blurring arising from their intrinsically diffuse light emission. While depth-of-field extension in scintillation faces fundamental limitations absent in microscopy, this approach reveals promising avenues, including stacked scintillators, selective spatial-frequency enhancement, and X-ray energy-dependent imaging. These results clarify the key distinctions in adapting wavefront engineering to scintillation and its potential to enable tailored detection strategies."}],"extern":"1","OA_place":"repository","OA_type":"green","language":[{"iso":"eng"}],"publication":"ACS Photonics","scopus_import":"1","issue":"7","publication_identifier":{"eissn":["2330-4022"]},"date_published":"2026-03-01T00:00:00Z","article_processing_charge":"No","fulldoi":"https://doi.org/10.1021/acsphotonics.5c03124","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2601.09830","open_access":"1"}],"arxiv":1,"publication_status":"published","year":"2026","quality_controlled":"1","intvolume":"        13","volume":13,"doi":"10.1021/acsphotonics.5c03124","day":"01","oa":1,"external_id":{"arxiv":["2601.09830"]},"publisher":"American Chemical Society","month":"03"},{"tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"ddc":["530"],"intvolume":"        15","publication_status":"published","year":"2026","quality_controlled":"1","pmid":1,"article_processing_charge":"No","date_published":"2026-03-03T00:00:00Z","main_file_link":[{"url":"https://doi.org/10.1038/s41377-025-02166-5","open_access":"1"}],"fulldoi":"https://doi.org/10.1038/s41377-025-02166-5","oa":1,"day":"03","publisher":"Springer Nature","month":"03","external_id":{"pmid":[" 41775693"]},"article_number":"145","doi":"10.1038/s41377-025-02166-5","volume":15,"status":"public","author":[{"last_name":"Salamin","first_name":"Yannick","full_name":"Salamin, Yannick"},{"full_name":"Yang, Gaojie","last_name":"Yang","first_name":"Gaojie"},{"last_name":"Mills","first_name":"Brian","full_name":"Mills, Brian"},{"first_name":"André","last_name":"Grossi Fonseca","full_name":"Grossi Fonseca, André"},{"full_name":"Roques-Carmes, Charles","first_name":"Charles","last_name":"Roques-Carmes","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82"},{"first_name":"Quansan","last_name":"Yang","full_name":"Yang, Quansan"},{"full_name":"Beroz, Justin","first_name":"Justin","last_name":"Beroz"},{"full_name":"Kooi, Steven E.","first_name":"Steven E.","last_name":"Kooi"},{"full_name":"de Miguel Comella, Marc","first_name":"Marc","last_name":"de Miguel Comella"},{"last_name":"Mak","first_name":"Kiran","full_name":"Mak, Kiran"},{"first_name":"Sachin","last_name":"Vaidya","full_name":"Vaidya, Sachin"},{"full_name":"Oran, Daniel","first_name":"Daniel","last_name":"Oran"},{"full_name":"Swain, Corban","first_name":"Corban","last_name":"Swain"},{"last_name":"Sun","first_name":"Yi","full_name":"Sun, Yi"},{"first_name":"Shai","last_name":"Maayani","full_name":"Maayani, Shai"},{"full_name":"Sloan, Jamison","first_name":"Jamison","last_name":"Sloan"},{"full_name":"Amin Elfadil Elawad, Amel","first_name":"Amel","last_name":"Amin Elfadil Elawad"},{"last_name":"Lopez","first_name":"Josue J.","full_name":"Lopez, Josue J."},{"last_name":"Boyden","first_name":"Edward S.","full_name":"Boyden, Edward S."},{"first_name":"Marin","last_name":"Soljačić","full_name":"Soljačić, Marin"}],"date_created":"2026-03-30T12:22:47Z","title":"Three-dimensional nanophotonics with spatially modulated optical properties","_id":"21537","extern":"1","abstract":[{"lang":"eng","text":"Nanophotonics has revolutionized the control of light-matter interactions in various fields of fundamental science and technology.

The presence of non-Hermiticity leads to many topological physics phenomena and device applications. In the non-Hermitian energy band theory, the foundation of these physics and applications, both energies and wave vectors take complex values. The energy bands thus become a Riemann surface, and such an energy-band Riemann surface underlies all important signatures of non-Hermitian topology. Despite a long history and recent theoretical interests, the energy-band Riemann surface has not been experimentally studied. Here, we provide a photonic observation of the energy-band Riemann surface of a non-Hermitian system. This is achieved by a tunable imaginary gauge transformation in photonic synthetic frequency dimensions. From measured topologies of the Riemann surface, we reveal the complex-energy winding, the open-boundary-condition spectrum, the generalized Brillouin zone, and the branch points.

While Bitcoin,\r\nbased on Proof-of-Work (PoW), was the first protocol in this model, significant\r\nresearch has focused on permissionless protocols using alternative physical resources,\r\nspecifically Proof-of-Space (PoSpace) and Verifiable Delay Functions (VDFs). This\r\nthesis investigates the theoretical limits and design space of longest-chain protocols in\r\nthe fully permissionless and dynamically available settings using these three resources.\r\nFirst, we address the feasibility of blockchains relying solely on storage as a resource.\r\nWe prove a fundamental impossibility result: there exists no secure longest-chain\r\nprotocol based exclusively on Proof-of-Space in the fully permissionless or dynamically\r\navailable settings. Further, we quantify the adversarial capabilities required to execute\r\na double-spend attack. Our result formally justifies the necessity of coupling PoSpace\r\nwith time-dependent primitives (such as VDFs) or to move to less permissive settings\r\n(quasi-permissionless or permissioned) to ensure security.\r\nSecond, we generalize Nakamoto-like heaviest chain consensus to protocols utilizing\r\ncombinations of multiple physical resources. We analyze chain selection rules governed\r\nby a weight function Γ(S, V,W), which assigns weight to blocks based on recorded\r\nSpace (S), VDF speed (V ), and Work (W). We provide a complete classification\r\nof secure weight functions, proving that a weight function is secure against private\r\ndouble-spend attacks if and only if it is homogeneous in the timed resources (V,W)\r\nand sub-homogeneous in S. This framework unifies existing protocols like Bitcoin and\r\nChia under a single theoretical model and provides a powerful tool for designing new\r\nlongest-chain blockchains from a mix of physical resources.","lang":"eng"}],"_id":"21651","title":"On secure chain selection rules from physical resources in a permissionless setting","author":[{"last_name":"Baig","first_name":"Mirza Ahad","id":"3EDE6DE4-AA5A-11E9-986D-341CE6697425","full_name":"Baig, Mirza Ahad"}],"date_created":"2026-04-02T09:31:34Z","status":"public","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","date_updated":"2026-04-15T08:45:19Z","related_material":{"record":[{"status":"public","relation":"part_of_dissertation","id":"21134"},{"relation":"part_of_dissertation","id":"20587","status":"public"}]},"license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","citation":{"ama":"Baig MA.
