In particular, the ability of these envelope gravito-inertial modes to couple with those trapped in the radiative interior could open up new opportunities for probing the deep-layer dynamics of solar-type stars. The possibility for such a coupling to occur is particularly favoured among pre-main-sequence (PMS) solar-type stars. Indeed, due to the contraction of the protostellar object, they are able to reach high rotation frequencies before nuclear reactions are ignited and magnetic braking becomes the driving mechanism for their rotational evolution. In this work, we studied the coupling between the envelope inertial waves and the radiative interior g modes in PMS stars, focussing on the case of prograde dipolar modes. We considered the cases of 0.5 M⊙ and 1 M⊙ PMS models, each with three different scenarios of rotational evolution. We show that for stars that have formed with a sufficient amount of angular momentum, this coupling can occur in frequency ranges that are accessible to space-borne photometry, creating inertial dips in the period spacing pattern. Using an asymptotic analysis, we characterised the shape of these inertial dips to show that they depend on rotation and on the stiffness of the convective-radiative interface."}],"scopus_import":"1","date_published":"2026-03-01T00:00:00Z"},{"arxiv":1,"ddc":["530"],"acknowledgement":"We thank Max Hachmann, Andreas Hemmerich, and Yann Kiefer for valuable discussions.

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"}],"oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file":[{"file_size":2131627,"relation":"main_file","file_id":"21667","date_created":"2026-04-07T09:34:31Z","creator":"dernst","access_level":"open_access","content_type":"application/pdf","file_name":"2026_PhysicalReviewResearch_Becker.pdf","date_updated":"2026-04-07T09:34:31Z","checksum":"339bff9d13486a8028049404988b9b0b","success":1}],"author":[{"last_name":"Becker","first_name":"A.","full_name":"Becker, A."},{"first_name":"Georgios","full_name":"Koutentakis, Georgios","id":"d7b23d3a-9e21-11ec-b482-f76739596b95","last_name":"Koutentakis"},{"first_name":"P.","full_name":"Schmelcher, P.","last_name":"Schmelcher"}],"article_type":"original","publication_status":"published","project":[{"grant_number":"F100403","_id":"7c040762-9f16-11ee-852c-dd79eeee4ab3","name":"Coherent Optical Metrology Beyond Electric-Dipole-Allowed Transitions"}],"title":"Two-body Kapitza-Dirac scattering of one-dimensional ultracold atoms","oa_version":"Published Version","_id":"21660","year":"2026","month":"03","article_processing_charge":"Yes","corr_author":"1","external_id":{"arxiv":["2512.15260"]},"OA_place":"publisher","has_accepted_license":"1","date_updated":"2026-04-07T09:37:57Z","publication_identifier":{"issn":["2643-1564"]},"quality_controlled":"1","language":[{"iso":"eng"}],"intvolume":"         8","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"department":[{"_id":"MiLe"}],"PlanS_conform":"1","article_number":"013297","date_created":"2026-04-05T22:01:32Z","file_date_updated":"2026-04-07T09:34:31Z","type":"journal_article","day":"18","publisher":"American Physical Society","doi":"10.1103/rdsn-stlq","volume":8,"citation":{"ama":"Becker A, Koutentakis G, Schmelcher P.

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"}],"scopus_import":"1","date_published":"2026-03-09T00:00:00Z","status":"public","OA_type":"hybrid","acknowledgement":"This research was funded by the European Union’s Horizon 2020 research and innovation programme under Marie Skłodowska-Curie grant agreements 101008233 (MISSION)\r\nand 101034413 (IST-BRIDGE), by the Interreg North Sea project STORM_SAFE, by a KI-Starter grant from the Ministerium für Kultur und Wissenschaft NRW, by NWO VENI grant no. 639.021.754, and by NWO VIDI grant VI.Vidi.223.110 (TruSTy).

Ever more powerful edge devices, such as smartphones, have become\r\nubiquitous in most societies on earth. Through text typed, photos taken and apps used,\r\nthese devices, which we refer to as clients, generate enormous amounts of high quality and\r\ncomplex data. Moreover, the nature of these devices means the data they generate is often\r\nsensitive and privacy concerns prevent it being gathered and stored in a central location. This\r\npresents a challenge to the modern machine learning paradigm that requires central access\r\nto large amounts of data. Federated learning (FL) has emerged as one of the answers to\r\nthis problem. Rather than bringing the data to the model, FL sends the model to the data.\r\nModel training takes place on device, with periodically synchronized updates, allowing data to\r\nremain locally stored. While this approach offers significant privacy advantages it comes with\r\nits own set of unique challenges. These include: data heterogeneity, the notion that different\r\ndevices generate data in distinct ways which can negatively impact training dynamics; systems\r\nheterogeneity, meaning that different devices may have differing hardware specifications; high\r\ncommunication costs, which are induced by the repeated transferring of models over the\r\nnetwork and low device computational power, which limits the use of larger models on device.\r\nIn this thesis we present a range of methods for federated learning. We focus primarily on\r\nthe challenge of data heterogeneity, though the methods presented are designed to be well\r\nadapted to the other challenges of a federated setting, such as the constraints of limited\r\ncompute and communication overhead. We first present a method for explicitly modeling client\r\ndata heterogeneity. The approach formulates clients as samples from a certain probability\r\ndistribution and infers the parameters of this distribution from the available training clients.\r\nThis learned distribution then represents the heterogeneity present among the clients and can\r\nbe sampled from in order to create new simulated clients that are similar to the real clients we\r\nhave observed so far. Following this we present two methods for directly dealing with data\r\nheterogeneity through personalization. Highly heterogeneous client data distributions can mean\r\nthat learning a single global model becomes suboptimal, and some form of personalization of\r\nmodels to each individual client is required. Our approaches are based around hypernetworks,\r\nwhich we use to generate personalized model parameters without the need for additional\r\ntraining or finetuning. In the first approach we focus on generating full parameterizations of\r\nclient models using learned embeddings of client data and labels, with a hypernetwork located\r\non the central server. In the second approach we address the more challenging scenario where\r\nwe want to generate a personalized model for a client without any label information. The\r\nhypernetwork is trained to generate a low dimensional representation of a client’s personalized\r\nmodel parameters, allowing it to be transferred to and run on the client devices. In our final\r\npresented method, we change our focus and rather than aim to directly address the challenge\r\nof data heterogeneity, we instead ensure we are unaffected by it. This is done in the context\r\nof k-means clustering and we present a method for federated clustering with a focus on added\r\nprivacy guarantees.","lang":"eng"}],"month":"02","alternative_title":["ISTA Thesis"],"article_processing_charge":"No","title":"Data heterogeneity and personalization in federated learning","oa_version":"Published Version","_id":"21198","year":"2026","acknowledged_ssus":[{"_id":"ScienComp"}],"department":[{"_id":"GradSch"},{"_id":"ChLa"}],"file_date_updated":"2026-02-27T10:25:41Z","date_created":"2026-02-09T14:59:53Z","corr_author":"1","supervisor":[{"first_name":"Christoph","full_name":"Lampert, Christoph","id":"40C20FD2-F248-11E8-B48F-1D18A9856A87","last_name":"Lampert","orcid":"0000-0001-8622-7887"}],"OA_place":"publisher","has_accepted_license":"1","date_updated":"2026-04-07T11:46:11Z","publication_identifier":{"issn":["2663-337X"]},"language":[{"iso":"eng"}],"type":"dissertation","related_material":{"record":[{"status":"public","relation":"part_of_dissertation","id":"20819"},{"status":"public","relation":"part_of_dissertation","id":"17411"},{"status":"public","id":"18120","relation":"part_of_dissertation"},{"relation":"part_of_dissertation","id":"21207","status":"public"}]},"doi":"10.15479/AT-ISTA-21198","publisher":"Institute of Science and Technology Austria","day":"09","page":"158","citation":{"apa":"Scott, J.

Central to this exploration is the question of how structure, both geometric and topological, persists or changes under approximation, sampling, or deformation. The work develops new approaches to skeletal and grid-based representations of surfaces, reveals the full expressive capacity of persistence vineyards, and applies topological methods to the longstanding problem of equilibria in electrostatic fields.

Given a function from a topological space to $\\mathbb{R}$, TDA provides tools to simplify and study the importance of topological features: in particular, the $l^{th}$-dimensional persistence diagram encodes the $l$-homology in the sublevel set as the function value increases as a set of points in the plane. Given a continuous one-parameter family of such functions, we can combine the persistence diagrams into an object known as a vineyard, which track the evolution of points in the persistence diagram. If we further restrict that family of functions to be periodic, we identify the two ends of the vineyard, yielding a closed vineyard. This allows the study of monodromy, which in this context means that following the family of functions for a period permutes the set of points in a non-trivial way. In this work, given a link and value $l$, we construct a topological space and periodic family of functions such that the closed $l$-vineyard contains this link. This shows that vineyards are topologically as rich as one could possibly hope. Importantly, it has at least two immediate consequences: First, monodromy of any periodicity can occur in a $l$-vineyard, answering a variant of a question by [Arya et al 2024]. To exhibit this, we also reformulate monodromy in a more geometric way, which may be of interest in itself. Second, distinguishing vineyards is likely to be difficult given the known difficulty of knot and link recognition, which have strong connections to many NP-hard problems.","lang":"eng"}],"language":[{"iso":"eng"}],"date_published":"2026-01-02T00:00:00Z","status":"public","OA_place":"repository","date_updated":"2026-04-07T11:42:48Z","arxiv":1,"corr_author":"1","external_id":{"arxiv":["2504.11203"]},"publication":"arXiv","article_processing_charge":"No","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2504.11203","open_access":"1"}],"month":"01","citation":{"short":"E.

Most applications to solid-state systems have targeted weakly interacting or single-ion states, leaving the manipulation of many-body wavefunctions largely unexplored. Here we use Floquet engineering to achieve quantum control of a strongly correlated Hubbard exciton in the one-dimensional Mott insulator Sr2CuO3. A non-resonant mid-infrared optical field coherently dresses the exciton wavefunction, driving its rotation between bright and dark states.

Open clusters offer the most straightforward way to empirically determine the IFMR, as their well-defined ages allow for direct progenitor lifetime estimates. We construct the most comprehensive open cluster WD IFMR to date by combining new spectroscopy of 22 WDs with an extensive literature review of WDs with strong cluster associations. To minimize systematics, we restrict our analysis to spectroscopically confirmed hydrogen-atmosphere (DA) WDs consistent with single-stellar origins. We separately analyze a subset with reliable Gaia-based astrometric membership assessments, as well as a full sample that adds WDs with strong cluster associations whose membership cannot be reliably assessed with Gaia. The Gaia-based sample includes 69 spectroscopically confirmed DA WDs, more than doubling the sample size of previous Gaia-based open cluster IFMRs. The full sample, which includes 53 additional literature WDs,\r\nincreases the total number of cluster WDs by over 50% relative to earlier works. We provide functional forms for both the Gaia-based and full-sample IFMRs. The Gaia-based result useful for Mi � 2.67 M⊙ is Mf = [0.179 0.100H (Mi 3.84 M )] × (Mi 3.84 M ) + 0.628 M , where H(x) is the Heaviside step function. Comparing our IFMR to recent literature, we identify significant deviations from best-fit IFMRs derived from both Gaia-based volume-limited samples of field WDs and double WD binaries, with the largest discrepancy occurring for initial masses of about 5 M⊙."}],"scopus_import":"1","date_published":"2026-01-01T00:00:00Z","month":"01","article_processing_charge":"Yes","title":"The White Dwarf initial–final mass relation from open clusters in Gaia DR3","keyword":["White dwarf stars","Open star clusters","Compact objects","Stellar evolution"],"oa_version":"Published Version","year":"2026","_id":"21725","issue":"1","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_number":"69","department":[{"_id":"IlCa"}],"PlanS_conform":"1","file_date_updated":"2026-04-13T08:36:50Z","date_created":"2026-04-12T22:01:52Z","external_id":{"arxiv":["2510.24877"]},"date_updated":"2026-04-13T08:39:39Z","has_accepted_license":"1","OA_place":"publisher","publication_identifier":{"issn":["0004-637X"],"eissn":["1538-4357"]},"intvolume":"       996","quality_controlled":"1","language":[{"iso":"eng"}],"publication":"The Astrophysical Journal","type":"journal_article","publisher":"IOP Publishing","day":"01","doi":"10.3847/1538-4357/ae18c8","volume":996,"citation":{"ama":"Miller DR, Caiazzo I, Heyl J, et al.

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"}],"date_published":"2026-01-14T00:00:00Z","language":[{"iso":"eng"}],"arxiv":1,"external_id":{"arxiv":["2601.09830"]},"OA_type":"green","OA_place":"repository","date_updated":"2026-04-13T11:26:08Z","article_processing_charge":"No","publication":"arXiv","month":"01","main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.2601.09830"}],"extern":"1","oa_version":"Preprint","_id":"21699","citation":{"chicago":"Chen, Joshua, Sachin Vaidya, Simo Pajovic, Seou Choi, William Michaels, Louis Martin-Monier Louis Martin-Monier, Juejun Hu, Carol Cogswell, Charles Roques-Carmes, and Marin Soljačić. “Wavefront Engineering for Scintillation-Based Imaging.” <i>ArXiv</i>, n.d. <a href=\"https://doi.org/10.48550/arXiv.2601.09830\">https://doi.org/10.48550/arXiv.2601.09830</a>.","ama":"Chen J, Vaidya S, Pajovic S, et al.

We performed high-resolution, single-progenitor cell lineage tracing in the embryonic mouse spinal cord using mosaic analysis with double markers (MADM). Our quantitative study of lineage progression revealed that spinal cord progenitors undergo highly variable numbers of proliferative, neurogenic, and gliogenic cell divisions. The nascent clonally-related neurons migrate radially over large distances, span the dorsoventral axis, and even cross the midline, demonstrating striking bilaterality. Molecular and morphometric analysis indicate high levels of progenitor multipotency, with an individual progenitor capable of producing several molecularly and morphologically distinct neuron types, as well as astrocytes.

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"}],"scopus_import":"1","date_published":"2026-03-01T00:00:00Z","status":"public","OA_type":"hybrid","arxiv":1,"ddc":["530"],"acknowledgement":"We thank Wenchao Ge and Allison Carter for feedback on the manuscript.

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."}],"date_published":"2026-03-04T00:00:00Z","oa":1,"file":[{"checksum":"c3986dba90653dac97adba662ebff238","date_updated":"2026-04-13T08:24:13Z","file_name":"PhD-Thesis-Mirza-Ahad-Baig - Library Submission.zip","content_type":"application/x-zip-compressed","access_level":"closed","creator":"mbaig","date_created":"2026-04-03T17:28:48Z","file_id":"21655","relation":"source_file","file_size":139353434},{"checksum":"292a5989262521f7c145a109d1f348cb","file_name":"2026_Baig_Mirza_Ahad_Thesis.pdf","date_updated":"2026-04-15T07:37:25Z","content_type":"application/pdf","creator":"mbaig","date_created":"2026-04-03T17:29:30Z","access_level":"open_access","file_id":"21656","file_size":1942037,"relation":"main_file"}],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","author":[{"last_name":"Baig","first_name":"Mirza Ahad","id":"3EDE6DE4-AA5A-11E9-986D-341CE6697425","full_name":"Baig, Mirza Ahad"}],"license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","publication_status":"published","related_material":{"record":[{"status":"public","id":"21134","relation":"part_of_dissertation"},{"status":"public","relation":"part_of_dissertation","id":"20587"}]},"type":"dissertation","day":"04","doi":"10.15479/AT-ISTA-21651","publisher":"Institute of Science and Technology Austria","citation":{"ama":"Baig MA.

While the stoichiometric compound with x = 1/3 exhibits a single magnetic transition, samples with x≤0.325 display two transitions with an anomalous Hall effect (AHE) emerging in the lower temperature phase. Here, we resolve the spin structure in each phase by employing a suite of magneto-optical probes that include the discovery of anomalous magneto-birefringence: a spontaneous time-reversal sensitive rotation of the principal optic axes. A symmetry-based analysis identifies the AHE-active phase as an anisotropic (2+1)Q state, in which magnetic modulation at one wavevector (Q) differs in symmetry from that at the remaining two. The (2+1)Q state naturally exhibits scalar spin chirality as a mechanism for the AHE and expands the classification of multi-Q magnetic phases."}],"scopus_import":"1","date_published":"2026-04-09T00:00:00Z","status":"public","OA_type":"gold","acknowledgement":"We thank Linda Ye and Yue Sun for helpful discussion.

In this Letter, we propose a new formation scenario for black hole (BH) + Be star binaries (hereafter BHBe binaries), where the Be star is produced through the wind Roche lobe overflow (WRLOF) mechanism. Our analysis is based on numerical simulations of the WRLOF process in massive binaries, building on recent theoretical work. We demonstrate that the WRLOF model can efficiently form BHBe binaries under reasonable assumptions on stellar wind velocities. Using rapid binary population synthesis, we estimate the population of such systems in the Milky Way, predicting ∼1800−3200 currently existing BHBe binaries originating from the WRLOF channel. These systems are characterized by high eccentricities and exceptionally wide orbits, with typical orbital periods exceeding 1000 days and a peak distribution around ∼10,000 days. Due to their long orbital separations, these BHBe binaries are promising targets for future detection via astrometric and interferometric observations.","lang":"eng"}],"arxiv":1,"ddc":["520"],"acknowledgement":"We are deeply grateful to the anonymous referee for the insightful comments, which have significantly improved the quality of this work.

They are force-free and can be described as hydrodynamic force dipoles: pushers or pullers. This modelling description is broadly used in biological physics and active matter research, and it has successfully predicted, for example, the superfluid behaviour of suspensions of pushers or the bend instability and emergence of turbulent flows in active nematics. However, this description accounts only for the translational motion of the swimming body and neglects the effects of hydrodynamic torque dipoles, which are relevant to bacteria with rotary motor-driven flagella, such as swimming Escherichia coli. Here we show that the torque dipole of confined swimming E. coli can power the persistent rotation of symmetric discs. The torque dipole leads to a traction force on the discs, an additive mechanism that is both contactless and independent of the orientation of the bacteria. Our results indicate that the torque dipole of swimming E. coli is notable in confined geometries, which is relevant to bacterial transport through porous materials, biofilms and the development of chiral fluids.","lang":"eng"}],"date_published":"2026-03-27T00:00:00Z","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"full_name":"Grober, Daniel B","id":"c692f879-718d-11ee-81f0-da7caa79c783","first_name":"Daniel B","last_name":"Grober"},{"last_name":"Dhar","full_name":"Dhar, Tanumoy","first_name":"Tanumoy"},{"last_name":"Saintillan","first_name":"David","full_name":"Saintillan, David"},{"id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","full_name":"Palacci, Jérémie A","first_name":"Jérémie A","last_name":"Palacci","orcid":"0000-0002-7253-9465"}],"article_type":"original","publication_status":"epub_ahead","project":[{"name":"VULCAN: matter, powered from within","_id":"bdac72da-d553-11ed-ba76-eae56e802b74","grant_number":"101086998"}]}]
