Extending it into the nonlinear regime broadens its scope and can provide valuable insight into interactions among these modes. However, interpreting nonlinear spectra is challenging because resonant features in this case do not always reflect intrinsic material dynamics. 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. These results demonstrate the crucial role of kinematic effects in shaping THz-induced Kerr response and establish a framework for interpreting nonlinear spectroscopies in complex materials.","lang":"eng"}],"month":"03","fulldoi":"https://doi.org/10.1103/1c5k-9z82","date_updated":"2026-03-23T13:11:09Z","publication_status":"published","issue":"10","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","department":[{"_id":"ZhAl"},{"_id":"GradSch"}],"has_accepted_license":"1","article_processing_charge":"Yes (via OA deal)","article_number":"106901","_id":"21469","date_created":"2026-03-22T23:04:31Z","file_date_updated":"2026-03-23T13:08:06Z","article_type":"original","author":[{"full_name":"Shen, Chao","id":"f84c083e-dc8d-11ea-abe3-aaf3d822a8bb","last_name":"Shen","first_name":"Chao"},{"first_name":"Maximilian","full_name":"Frenzel, Maximilian","last_name":"Frenzel"},{"full_name":"Maehrlein, Sebastian F.","last_name":"Maehrlein","first_name":"Sebastian F."},{"orcid":"0000-0002-7183-5203","first_name":"Zhanybek","full_name":"Alpichshev, Zhanybek","last_name":"Alpichshev","id":"45E67A2A-F248-11E8-B48F-1D18A9856A87"}],"quality_controlled":"1","title":"Disentangling electronic and ionic nonlinear polarization effects in bulk THz Kerr response","scopus_import":"1","file":[{"relation":"main_file","creator":"dernst","access_level":"open_access","file_id":"21475","checksum":"712b05b4b0e0fbe9fd426a8c9d41ce20","success":1,"file_size":1375532,"date_updated":"2026-03-23T13:08:06Z","date_created":"2026-03-23T13:08:06Z","file_name":"2026_PhysicalReviewLetters_Shen.pdf","content_type":"application/pdf"}],"publisher":"American Physical Society","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"day":"13","acknowledgement":"Z. A. acknowledges support from the collaborative research project SFB Q-M&S funded by the Austrian Science Fund (FWF, Grant No. PR1050F8602).

In optical fields, where multiple vortices coexist, the local nature of vortex OAM and the absence of a common rotation axis make the total OAM of the field difficult to quantify. 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. By unifying OAM characterization into a single figure of merit, the R index enables direct comparison across diverse beam profiles and facilitates the identification of optimal configurations for both foundational studies and applied technologies.","lang":"eng"}],"status":"public","project":[{"_id":"7c040762-9f16-11ee-852c-dd79eeee4ab3","grant_number":"F100403","name":"Coherent Optical Metrology Beyond Electric-Dipole-Allowed Transitions"}],"doi":"10.1088/2515-7647/ae3506","OA_type":"hybrid","date_published":"2026-03-10T00:00:00Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png"},"ddc":["530"],"citation":{"ieee":"M.

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.","lang":"eng"}],"month":"03","day":"09","acknowledgement":"We acknowledge the generosity of the patients, who contributed time and effort to take part in this study.","PlanS_conform":"1","volume":8,"publication":"Brain Communications","intvolume":"         8","oa":1,"language":[{"iso":"eng"}],"OA_place":"publisher","corr_author":"1","year":"2026","date_created":"2026-03-22T23:04:34Z","_id":"21473","file_date_updated":"2026-03-23T14:27:39Z","DOAJ_listed":"1","article_type":"original","author":[{"full_name":"Cardenas, Araceli R.","last_name":"Cardenas","first_name":"Araceli R."},{"id":"44B06F76-F248-11E8-B48F-1D18A9856A87","full_name":"Ramirez Villegas, Juan F","last_name":"Ramirez Villegas","first_name":"Juan F"},{"last_name":"Kovach","full_name":"Kovach, Christopher K.","first_name":"Christopher K."},{"first_name":"Phillip E.","full_name":"Gander, Phillip E.","last_name":"Gander"},{"full_name":"Cole, Rachel C.","last_name":"Cole","first_name":"Rachel C."},{"first_name":"Andrew J.","full_name":"Grossbach, Andrew J.","last_name":"Grossbach"},{"full_name":"Kawasaki, Hiroto","last_name":"Kawasaki","first_name":"Hiroto"},{"first_name":"Jeremy D.W.","full_name":"Greenlee, Jeremy D.W.","last_name":"Greenlee"},{"full_name":"Howard, Matthew A.","last_name":"Howard","first_name":"Matthew A."},{"full_name":"Nourski, Kirill V.","last_name":"Nourski","first_name":"Kirill V."},{"first_name":"Matthew I.","last_name":"Banks","full_name":"Banks, Matthew I."},{"full_name":"Voss, Michelle W.","last_name":"Voss","first_name":"Michelle W."}],"quality_controlled":"1","title":"Exercise enhances hippocampal-cortical ripple interactions in the human brain","scopus_import":"1","file":[{"checksum":"b5b45c16defeaf88056fc3b939bd0350","success":1,"access_level":"open_access","file_id":"21478","creator":"dernst","relation":"main_file","file_name":"2026_BrainCommunications_Cardenas.pdf","date_updated":"2026-03-23T14:27:39Z","date_created":"2026-03-23T14:27:39Z","content_type":"application/pdf","file_size":33974419}],"publisher":"Oxford University Press","publication_identifier":{"eissn":["2632-1297"]}},{"publication_status":"published","issue":"9","date_updated":"2026-03-23T15:39:34Z","fulldoi":"https://doi.org/10.1103/rbg2-f61m","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_number":"090801","department":[{"_id":"MaSe"}],"article_processing_charge":"Yes (in subscription journal)","has_accepted_license":"1","ddc":["530"],"citation":{"chicago":"Votto, Matteo, Marko Ljubotina, Cécilia Lancien, J.

The protocol takes as input classical shadows corresponding to local randomized measurements, and outputs the tensors of an MPO maximizing a suitably defined fidelity with the experimental state. 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. We experimentally demonstrate our protocol by learning entangled quantum states of up to N = 96 qubits in a superconducting quantum processor. Our method upgrades classical shadows to large-scale quantum computation and simulation experiments."}],"month":"03","external_id":{"arxiv":["2507.12550"]},"type":"journal_article","oa_version":"Published Version","publication":"Physical Review Letters","volume":136,"acknowledgement":"We acknowledge insightful discussions with Antoine Browaeys, Mari Carmen Bañuls, Soonwon Choi, Thierry Lahaye, Daniel Stilck-França, Georgios Styliaris, and Xavier Waintal.

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."}],"month":"03","OA_type":"diamond","doi":"10.1051/0004-6361/202557114","project":[{"_id":"bd9b2118-d553-11ed-ba76-db24564edfea","grant_number":"101076224","name":"Young galaxies as tracers and agents of cosmic reionization"}],"status":"public","citation":{"apa":"Kramarenko, I., Rosdahl, J., Blaizot, J., Matthee, J.

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."}],"oa_version":"Published Version","external_id":{"pmid":["41851325"]},"type":"journal_article","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","ec_funded":1,"date_updated":"2026-04-28T12:06:01Z","fulldoi":"https://doi.org/10.1038/s41586-025-10088-w","publication_status":"published","issue":"8106","pmid":1,"has_accepted_license":"1","article_processing_charge":"Yes (via OA deal)","department":[{"_id":"ScWa"},{"_id":"GradSch"},{"_id":"LifeSc"}]},{"abstract":[{"text":"Currently, pharmacogenetics relies on partially annotated star alleles, leaving novel variants and complex haplotypes uninterpretable.

Altogether we analyzed 541 PharmVar alleles, high‑throughput CYP2C9 and CYP2C19 mutational maps, and 200 642 UK Biobank exomes linked with health records containing antidepressant treatment outcomes. 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). Our findings show that computational predictors deliver star allele accuracy while overcoming their limitations. With additional validation, computational tools could enhance clinical decision frameworks by enabling continuous scoring, incorporating previously unknown variants, and providing genome-wide applicability.","lang":"eng"}],"month":"03","type":"journal_article","external_id":{"pmid":["41803106"]},"oa_version":"Published Version","ddc":["570"],"citation":{"apa":"Hajto, J., Piechota, M., Krätschmer, I., Konowalska, P., Boyle, G.

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."}]},{"article_processing_charge":"No","pmid":1,"article_number":"145","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","date_updated":"2026-04-27T07:59:10Z","fulldoi":"https://doi.org/10.1038/s41377-025-02166-5","publication_status":"published","oa_version":"Published Version","type":"journal_article","external_id":{"pmid":[" 41775693"]},"month":"03","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. Our findings demonstrate a unified framework in the studies of diverse effects in non-Hermitian topological physics through an experimental observation of energy-band Riemann surfaces.","lang":"eng"}],"month":"03","external_id":{"arxiv":["2510.08819"]},"type":"journal_article","oa_version":"Published Version","citation":{"mla":"Cheng, Dali, et al. “Experimental Observation of Energy-Band Riemann Surface.” <i>Science Advances</i>, vol. 12, no. 12, eaec8239, American Association for the Advancement of Science, 2026, doi:<a href=\"https://doi.org/10.1126/sciadv.aec8239\">10.1126/sciadv.aec8239</a>.","apa":"Cheng, D., Wang, H., Zhong, J., Lustig, E., Roques-Carmes, C., &#38; Fan, S.

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.

Our analysis focuses on tropical precipitation characteristics spanning a wide range of spatio-temporal scales—including the diurnal cycle, extreme precipitation, convective organization, and the Madden-Julian Oscillation (MJO)—along with interactions between convection and the thermodynamic environment. All three models commonly show weaker convective organization with smaller precipitation cells than observed, though the strength of the bias varies by model. This diversity is introduced by differences in the representation of (a) convective initiation affected by the convective sensitivity to moisture and (b) tropospheric moistening associated with deep convection. Models with stronger thermodynamic-convection coupling increase environmental moisture near convection, thereby enhancing convective organization. This has important upscale effects on the MJO; while IFS and NICAM capture its eastward propagation well, ICON has difficulty reproducing it. The amplitudes and phases of precipitation diurnal cycles over land show much greater disagreement among the models than over ocean, influenced by how convection is initiated. Biases in rain evaporation and cold pool formation hinder the propagation of mesoscale convection, leading to errors such as the misrepresentation of nocturnal convection moving off the coast of Sumatra in IFS and ICON. These results highlight the importance of thermodynamic-convection coupling in realistically simulating tropical convection across scales. To improve this coupling, kilometer-scale models require better representation of the interaction between resolved convection and three-dimensional turbulent mixing.","lang":"eng"}],"oa_version":"Published Version","type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","ec_funded":1,"publication_status":"published","issue":"3","fulldoi":"https://doi.org/10.1029/2025MS005343","date_updated":"2026-06-16T10:43:35Z","article_number":"e2025MS005343","article_processing_charge":"Yes","has_accepted_license":"1","department":[{"_id":"CaMu"}]},{"citation":{"ama":"Becker A, Koutentakis G, Schmelcher P.

Here, we develop a numerically exact two-body description of Kapitza-Dirac scattering for two contact-interacting atoms in a one-dimensional harmonic trap subjected to a pulsed optical lattice, enabling us to obtain the numerically exact dynamics. We map how interaction strength, lattice depth, lattice wave number, and pulse duration reshape the diffraction pattern, leading to an interaction-dependent population redistribution in real and momentum space. By comparing the exact dynamics to an impulsive sudden-approximation description, we delineate the parameter regimes where it remains accurate and those, notably at strong attraction and small lattice wave number, where it fails. Our results provide a controlled few-body benchmark for interacting Kapitza-Dirac scattering and quantitative guidance for Kapitza-Dirac-based probes of ultracold atomic systems.","lang":"eng"}],"month":"03","external_id":{"arxiv":["2512.15260"]},"type":"journal_article","oa_version":"Published Version","fulldoi":"https://doi.org/10.1103/rdsn-stlq","date_updated":"2026-04-07T09:37:57Z","publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_number":"013297","department":[{"_id":"MiLe"}],"has_accepted_license":"1","article_processing_charge":"Yes","_id":"21660","date_created":"2026-04-05T22:01:32Z","file_date_updated":"2026-04-07T09:34:31Z","scopus_import":"1","file":[{"file_size":2131627,"content_type":"application/pdf","date_created":"2026-04-07T09:34:31Z","file_name":"2026_PhysicalReviewResearch_Becker.pdf","date_updated":"2026-04-07T09:34:31Z","success":1,"checksum":"339bff9d13486a8028049404988b9b0b","relation":"main_file","creator":"dernst","file_id":"21667","access_level":"open_access"}],"publisher":"American Physical Society","publication_identifier":{"issn":["2643-1564"]},"DOAJ_listed":"1","author":[{"first_name":"A.","full_name":"Becker, A.","last_name":"Becker"},{"first_name":"Georgios","id":"d7b23d3a-9e21-11ec-b482-f76739596b95","last_name":"Koutentakis","full_name":"Koutentakis, Georgios"},{"full_name":"Schmelcher, P.","last_name":"Schmelcher","first_name":"P."}],"article_type":"original","quality_controlled":"1","title":"Two-body Kapitza-Dirac scattering of one-dimensional ultracold atoms","publication":"Physical Review Research","volume":8,"arxiv":1,"day":"18","acknowledgement":"We thank Max Hachmann, Andreas Hemmerich, and Yann Kiefer for valuable discussions.

Popular algorithms are policy iteration and variants of value iteration; in tool competitions, most participants rely on the latter. These algorithms generally need worst-case exponential time. However, the problem can equally be formulated as a linear programme, solvable in polynomial time. In this paper, we give a detailed overview of today’s state-of-the-art algorithms for MDP model checking with a focus on performance and correctness. We highlight their fundamental differences, and describe various optimizations and implementation variants. We experimentally compare floating-point and exact-arithmetic implementations of all algorithms on three benchmark sets using two probabilistic model checkers. Our results show that (optimistic) value iteration is a sensible default, but other algorithms are preferable in specific settings. This paper thereby provides a guide for MDP verification practitioners—tool builders and users alike.","lang":"eng"}],"oa_version":"Published Version","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png"},"date_published":"2026-03-09T00:00:00Z","ddc":["000"],"citation":{"apa":"Hartmanns, A., Junges, S., Quatmann, T., &#38; Weininger, M.

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.","lang":"eng"}],"scopus_import":"1","month":"01","author":[{"last_name":"Chen","full_name":"Chen, Joshua","first_name":"Joshua"},{"full_name":"Vaidya, Sachin","last_name":"Vaidya","first_name":"Sachin"},{"last_name":"Pajovic","full_name":"Pajovic, Simo","first_name":"Simo"},{"full_name":"Choi, Seou","last_name":"Choi","first_name":"Seou"},{"first_name":"William","last_name":"Michaels","full_name":"Michaels, William"},{"full_name":"Louis Martin-Monier, Louis Martin-Monier","last_name":"Louis Martin-Monier","first_name":"Louis Martin-Monier"},{"last_name":"Hu","full_name":"Hu, Juejun","first_name":"Juejun"},{"full_name":"Cogswell, Carol","last_name":"Cogswell","first_name":"Carol"},{"first_name":"Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","last_name":"Roques-Carmes","full_name":"Roques-Carmes, Charles"},{"last_name":"Soljačić","full_name":"Soljačić, Marin","first_name":"Marin"}],"type":"preprint","external_id":{"arxiv":["2601.09830"]},"title":"Wavefront engineering for scintillation-based imaging","oa_version":"Preprint","publication":"arXiv","fulldoi":"https://doi.org/10.48550/arXiv.2601.09830","date_updated":"2026-04-13T11:26:08Z","publication_status":"submitted","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"14","arxiv":1,"language":[{"iso":"eng"}],"article_number":"2601.09830","OA_place":"repository","year":"2026","oa":1,"article_processing_charge":"No"},{"article_processing_charge":"No","oa":1,"OA_place":"repository","article_number":"2601.21385","language":[{"iso":"eng"}],"year":"2026","arxiv":1,"day":"29","publication_status":"submitted","date_updated":"2026-04-13T11:28:06Z","fulldoi":"https://doi.org/10.48550/arXiv.2601.21385","publication":"arXiv","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","external_id":{"arxiv":["2601.21385"]},"type":"preprint","author":[{"first_name":"Jakob M.","last_name":"Grzesik","full_name":"Grzesik, Jakob M."},{"first_name":"Aviv","last_name":"Karnieli","full_name":"Karnieli, Aviv"},{"first_name":"Charles","last_name":"Roques-Carmes","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","full_name":"Roques-Carmes, Charles"},{"first_name":"Dylan S.","full_name":"Black, Dylan S.","last_name":"Black"},{"first_name":"Trung Kiên","last_name":"Lê","full_name":"Lê, Trung Kiên"},{"first_name":"Olav","full_name":"Solgaard, Olav","last_name":"Solgaard"},{"first_name":"Shanhui","full_name":"Fan, Shanhui","last_name":"Fan"},{"first_name":"Jelena","full_name":"Vučković, Jelena","last_name":"Vučković"}],"oa_version":"Preprint","title":"A general framework for interactions between electron beams and quantum optical systems","scopus_import":"1","abstract":[{"text":"We provide a theoretical framework to describe the dynamics of a free-electron beam interacting with quantized bound systems in arbitrary electromagnetic environments.

We leverage this enhanced coupling for experimentally feasible protocols in coherent qubit control and towards the nondestructive readout and projective control of the electron beam's quantum-number statistics.
