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."}]},{"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":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":"         8","publication_identifier":{"eissn":["2515-7647"]},"publication_status":"published","OA_place":"publisher","month":"03","year":"2026","citation":{"ista":"Bahl M, Koutentakis G, Maslov M, Jungnickel T, Gaßen T, Lemeshko M, Heckl OH. 2026.

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."}],"date_created":"2026-03-22T23:04:32Z","publication":"Journal of Physics: Photonics","type":"journal_article","department":[{"_id":"MiLe"}],"language":[{"iso":"eng"}],"day":"10","ddc":["530"],"author":[{"last_name":"Bahl","full_name":"Bahl, Monika","first_name":"Monika"},{"first_name":"Georgios","id":"d7b23d3a-9e21-11ec-b482-f76739596b95","full_name":"Koutentakis, Georgios","last_name":"Koutentakis"},{"orcid":"0000-0003-4074-2570","first_name":"Mikhail","id":"2E65BB0E-F248-11E8-B48F-1D18A9856A87","last_name":"Maslov","full_name":"Maslov, Mikhail"},{"first_name":"Tom","last_name":"Jungnickel","full_name":"Jungnickel, Tom"},{"full_name":"Gaßen, Timo","last_name":"Gaßen","first_name":"Timo"},{"orcid":"0000-0002-6990-7802","first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","full_name":"Lemeshko, Mikhail","last_name":"Lemeshko"},{"last_name":"Heckl","full_name":"Heckl, Oliver H.","first_name":"Oliver H."}],"OA_type":"hybrid","has_accepted_license":"1","scopus_import":"1","doi":"10.1088/2515-7647/ae3506","project":[{"grant_number":"F100403","_id":"7c040762-9f16-11ee-852c-dd79eeee4ab3","name":"Coherent Optical Metrology Beyond Electric-Dipole-Allowed Transitions"}],"date_updated":"2026-03-23T13:26:26Z","title":"The R-index: A universal metric for evaluating OAM content and mode purity in optical fields","file_date_updated":"2026-03-23T13:24:01Z","article_type":"original","article_number":"015071","oa_version":"Published Version","volume":8,"_id":"21470","date_published":"2026-03-10T00:00:00Z","corr_author":"1","arxiv":1,"oa":1,"issue":"1","acknowledgement":"This research was funded in whole or in part by the Austrian Science Fund (FWF) [10.55776/F1004].

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"}],"date_created":"2026-03-22T23:04:34Z","citation":{"ista":"Cardenas AR, Ramirez Villegas JF, Kovach CK, Gander PE, Cole RC, Grossbach AJ, Kawasaki H, Greenlee JDW, Howard MA, Nourski KV, Banks MI, Voss MW. 2026.

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.","lang":"eng"}],"citation":{"chicago":"Votto, Matteo, Marko Ljubotina, Cécilia Lancien, J.

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."}],"date_created":"2026-03-23T14:58:03Z","month":"03","DOAJ_listed":"1","OA_place":"publisher","publication_identifier":{"issn":["0004-6361"],"eissn":["1432-0746"]},"publication_status":"published","intvolume":"       707","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":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file":[{"checksum":"7429076b381dd498084f40ffd199e714","success":1,"access_level":"open_access","content_type":"application/pdf","creator":"dernst","file_size":904565,"file_id":"21492","date_created":"2026-03-23T15:44:09Z","date_updated":"2026-03-23T15:44:09Z","relation":"main_file","file_name":"2026_AstronomyAstrophysics_Kramarenko.pdf"}],"external_id":{"arxiv":["2509.05403"]},"status":"public","oa":1,"acknowledgement":"We thank the anonymous referee for the insightful comments that helped improve the manuscript.

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."}],"date_created":"2026-03-23T15:04:00Z","year":"2026","citation":{"chicago":"Grosjean, Galien M, Markus Ostermann, Markus Sauer, Michael Hahn, Christian M.

A key prerequisite is the feedback between auxin signaling and directional auxin transport, mediated by PIN transporters. Despite the developmental importance of canalization, the molecular components linking auxin perception to the regulation of PIN auxin transporters remain poorly understood. Here, we identify TOW, a novel and essential component of auxin canalization that links intracellular auxin signaling with cell surface auxin perception. TOW is regulated downstream of TIR1/AFB-Aux/IAA-WRKY23 transcriptional auxin signaling. tow mutants exhibit defects in regeneration and de novo vasculature formation, along with impaired formation of polarized, PIN-expressing auxin channels. At the subcellular level, these mutants display disrupted auxin-induced PIN polarization and altered PIN endocytic trafficking dynamics. TOW localizes predominantly to the plasma membrane, where it interacts with receptor-like kinases involved in auxin canalization, including the TMK1 auxin co-receptor and the CAMEL-CANAR complex. TOW promotes PIN interaction with these kinases and stabilizes PINs at the cell surface. Together, our findings identify TOW as a molecular link between intracellular and cell surface auxin signaling mechanisms that converge on PIN trafficking and polarity, providing new insights into how auxin signaling regulates directional auxin transport for the self-organizing formation of vasculature during flexible plant development."}],"date_created":"2026-03-23T15:11:16Z","quality_controlled":"1","year":"2026","citation":{"chicago":"Li, Mingyue, Nikola Rydza, Ewa Mazur, Gergely Molnar, Tomasz Nodzyński, and Jiří Friml. “Receptor-like-Kinase-Interacting Protein TOW Stabilizes PIN Transporters for Auxin Canalization.” <i>Current Biology</i>.

Their quantum counterparts have recently drawn attention for exhibiting highly degenerate eigenstates at zero energy—known as zero modes—stemming from chiral symmetry. Yet, the structure and implications of these zero modes remain poorly understood. In this work, we focus on the properties of the zero mode subspace in quantum kinetically constrained models with a U(1) particle-conservation symmetry. We use the U(1) East, which lacks inversion symmetry, and the inversion-symmetric U(1) East-West models to illustrate our two main results. First, we observe that the simultaneous presence of constraints and chiral symmetry generally leads to a parametric increase in the number of zero modes due to the fragmentation of the many-body\r\nHilbert space into disconnected sectors. Second, we generalize the concept of compact localized states from single-particle physics and introduce the notion of collective bound states, a special kind of nonergodic eigenstates that are robust to enlarging the system size. We formulate sufficient criteria for their existence, arguing that the degenerate zero mode subspace plays a central role, and demonstrate bound states in both example models and in a two-dimensional model, the U(1) North-East, and in the pairflip model, a system without particle conservation. Our results motivate a systematic study of bound states and their relation to ergodicity breaking, transport, and other properties of quantum kinetically constrained\r\nmodels.

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).

Using ensemble and single-molecule assays combined with cryo-electron microscopy (cryo-EM), we studied the interaction between pioneer TFs OCT4–SOX2 and the human BRG1/BRM-associated factor (BAF) complex on nucleosomes. BAF engages TF-bound substrates in two orientations, placing OCT4–SOX2 at either the remodeler ENTRY or EXIT site. At the ENTRY site, OCT4–SOX2 initially coexists with BAF without structural interference. However, continued DNA translocation is expected to cause collisions with bound TFs, which can trigger remodeling direction reversals or may induce TF dissociation. To accommodate TFs at the EXIT site, BAF undergoes structural rearrangements, and ensemble assays reveal a nucleosome subpopulation translocating away from TF-binding sites. Moreover, single-molecule experiments show that nucleosome-bound BAF frequently changes remodeling direction, and we identify an ADP-bound remodeler conformation as a potential intermediate.

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."}],"date_created":"2026-03-30T12:22:47Z","type":"journal_article","publication":"ACS Photonics","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2601.09830"}],"page":"1757–1766","OA_place":"repository","month":"03","date_updated":"2026-05-05T07:53:27Z","title":"Wavefront engineering for scintillation-based imaging","extern":"1","article_type":"original","volume":13,"oa_version":"Preprint","language":[{"iso":"eng"}],"day":"01","author":[{"first_name":"Joshua","full_name":"Chen, Joshua","last_name":"Chen"},{"first_name":"Sachin","full_name":"Vaidya, Sachin","last_name":"Vaidya"},{"first_name":"Simo","full_name":"Pajovic, Simo","last_name":"Pajovic"},{"last_name":"Choi","full_name":"Choi, Seou","first_name":"Seou"},{"last_name":"Michaels","full_name":"Michaels, William","first_name":"William"},{"full_name":"Martin-Monier, Louis","last_name":"Martin-Monier","first_name":"Louis"},{"first_name":"Juejun","full_name":"Hu, Juejun","last_name":"Hu"},{"first_name":"Carol","full_name":"Cogswell, Carol","last_name":"Cogswell"},{"id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","full_name":"Roques-Carmes, Charles","last_name":"Roques-Carmes","first_name":"Charles"},{"first_name":"Marin","last_name":"Soljačić","full_name":"Soljačić, Marin"}],"OA_type":"green","scopus_import":"1","doi":"10.1021/acsphotonics.5c03124","issue":"7","oa":1,"article_processing_charge":"No","publisher":"American Chemical Society","status":"public","external_id":{"arxiv":["2601.09830"]},"_id":"21532","date_published":"2026-03-01T00:00:00Z","arxiv":1},{"_id":"21537","date_published":"2026-03-03T00:00:00Z","oa":1,"article_processing_charge":"No","publisher":"Springer Nature","pmid":1,"external_id":{"pmid":[" 41775693"]},"status":"public","language":[{"iso":"eng"}],"day":"03","ddc":["530"],"author":[{"first_name":"Yannick","full_name":"Salamin, Yannick","last_name":"Salamin"},{"first_name":"Gaojie","last_name":"Yang","full_name":"Yang, Gaojie"},{"first_name":"Brian","full_name":"Mills, Brian","last_name":"Mills"},{"first_name":"André","last_name":"Grossi Fonseca","full_name":"Grossi Fonseca, André"},{"full_name":"Roques-Carmes, Charles","last_name":"Roques-Carmes","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","first_name":"Charles"},{"first_name":"Quansan","full_name":"Yang, Quansan","last_name":"Yang"},{"full_name":"Beroz, Justin","last_name":"Beroz","first_name":"Justin"},{"last_name":"Kooi","full_name":"Kooi, Steven E.","first_name":"Steven E."},{"first_name":"Marc","last_name":"de Miguel Comella","full_name":"de Miguel Comella, Marc"},{"first_name":"Kiran","full_name":"Mak, Kiran","last_name":"Mak"},{"first_name":"Sachin","full_name":"Vaidya, Sachin","last_name":"Vaidya"},{"last_name":"Oran","full_name":"Oran, Daniel","first_name":"Daniel"},{"first_name":"Corban","full_name":"Swain, Corban","last_name":"Swain"},{"first_name":"Yi","full_name":"Sun, Yi","last_name":"Sun"},{"full_name":"Maayani, Shai","last_name":"Maayani","first_name":"Shai"},{"last_name":"Sloan","full_name":"Sloan, Jamison","first_name":"Jamison"},{"last_name":"Amin Elfadil Elawad","full_name":"Amin Elfadil Elawad, Amel","first_name":"Amel"},{"first_name":"Josue J.","full_name":"Lopez, Josue J.","last_name":"Lopez"},{"full_name":"Boyden, Edward S.","last_name":"Boyden","first_name":"Edward S."},{"last_name":"Soljačić","full_name":"Soljačić, Marin","first_name":"Marin"}],"OA_type":"gold","doi":"10.1038/s41377-025-02166-5","scopus_import":"1","date_updated":"2026-04-27T07:59:10Z","title":"Three-dimensional nanophotonics with spatially modulated optical properties","extern":"1","article_type":"original","article_number":"145","volume":15,"oa_version":"Published Version","DOAJ_listed":"1","OA_place":"publisher","month":"03","quality_controlled":"1","year":"2026","citation":{"ieee":"Y.

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"}],"date_created":"2026-03-30T12:22:48Z","type":"journal_article","publication":"Science Advances","main_file_link":[{"url":"https://doi.org/10.1126/sciadv.aec8239","open_access":"1"}],"DOAJ_listed":"1","OA_place":"publisher","month":"03","intvolume":"        12","publication_identifier":{"issn":["2375-2548"]},"publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"issue":"12","article_processing_charge":"No","publisher":"American Association for the Advancement of Science","status":"public","external_id":{"arxiv":["2510.08819"]},"_id":"21583","date_published":"2026-03-18T00:00:00Z","arxiv":1,"date_updated":"2026-04-27T10:01:35Z","title":"Experimental observation of energy-band Riemann surface","extern":"1","article_type":"original","article_number":"eaec8239","oa_version":"Published Version","volume":12,"language":[{"iso":"eng"}],"day":"18","author":[{"full_name":"Cheng, Dali","last_name":"Cheng","first_name":"Dali"},{"first_name":"Heming","full_name":"Wang, Heming","last_name":"Wang"},{"first_name":"Janet","last_name":"Zhong","full_name":"Zhong, Janet"},{"full_name":"Lustig, Eran","last_name":"Lustig","first_name":"Eran"},{"full_name":"Roques-Carmes, Charles","last_name":"Roques-Carmes","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","first_name":"Charles"},{"full_name":"Fan, Shanhui","last_name":"Fan","first_name":"Shanhui"}],"OA_type":"gold","scopus_import":"1","doi":"10.1126/sciadv.aec8239"},{"alternative_title":["ISTA Thesis"],"publication_identifier":{"issn":["2663-337X"],"isbn":["978-3-99078-078-7"]},"publication_status":"published","supervisor":[{"first_name":"Krzysztof Z","orcid":"0000-0002-9139-1654","full_name":"Pietrzak, Krzysztof Z","last_name":"Pietrzak","id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87"}],"tmp":{"name":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","image":"/images/cc_by_nc_sa.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode","short":"CC BY-NC-SA (4.0)"},"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","citation":{"ista":"Baig MA. 2026.

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.

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."}],"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":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","publication_identifier":{"eissn":["1942-2466"]},"intvolume":"        18"},{"volume":8,"oa_version":"Published Version","article_number":"013297","article_type":"original","file_date_updated":"2026-04-07T09:34:31Z","date_updated":"2026-04-07T09:37:57Z","title":"Two-body Kapitza-Dirac scattering of one-dimensional ultracold atoms","project":[{"_id":"7c040762-9f16-11ee-852c-dd79eeee4ab3","grant_number":"F100403","name":"Coherent Optical Metrology Beyond Electric-Dipole-Allowed Transitions"}],"scopus_import":"1","PlanS_conform":"1","doi":"10.1103/rdsn-stlq","has_accepted_license":"1","OA_type":"gold","author":[{"last_name":"Becker","full_name":"Becker, A.","first_name":"A."},{"first_name":"Georgios","id":"d7b23d3a-9e21-11ec-b482-f76739596b95","full_name":"Koutentakis, Georgios","last_name":"Koutentakis"},{"first_name":"P.","full_name":"Schmelcher, P.","last_name":"Schmelcher"}],"ddc":["530"],"day":"18","language":[{"iso":"eng"}],"department":[{"_id":"MiLe"}],"external_id":{"arxiv":["2512.15260"]},"status":"public","file":[{"file_name":"2026_PhysicalReviewResearch_Becker.pdf","relation":"main_file","date_created":"2026-04-07T09:34:31Z","date_updated":"2026-04-07T09:34:31Z","file_id":"21667","file_size":2131627,"creator":"dernst","access_level":"open_access","content_type":"application/pdf","success":1,"checksum":"339bff9d13486a8028049404988b9b0b"}],"publisher":"American Physical Society","article_processing_charge":"Yes","acknowledgement":"We thank Max Hachmann, Andreas Hemmerich, and Yann Kiefer for valuable discussions.
