To this end, we develop libraries in Lean 4 that present definitions and results from diverse areas of MathematiCS (i.e., Mathematics and Computer Science). The aim is to create code that is understandable, believable, useful, and elegant. The code should stand for itself as much as possible without a need for documentation; however, this text redundantly documents our code artifacts and provides additional context that isn’t present in the code. This thesis is written for readers who know Lean 4 but are not familiar with any of the topics presented. We manifest truth and beauty in three formalized areas of MathematiCS.\r\n\r\nWe formalize general grammars in Lean 4 and use grammars to show closure of the class of type-0 languages under four operations; union, reversal, concatenation, and the Kleene star.\r\n\r\nOur second stop is the theory of optimization. Farkas established that a system of linear inequalities has a solution if and only if we cannot obtain a contradiction by taking a linear combination of the inequalities. We state and formally prove several Farkas-like theorems over linearly ordered fields in Lean 4. Furthermore, we extend duality theory to the case when some coefficients are allowed to take “infinite values”. Additionally, we develop the basics of the theory of optimization in terms of the framework called General-Valued Constraint Satisfaction Problems, and we prove that, if a Rational-Valued Constraint Satisfaction Problem template has symmetric fractional polymorphisms of all arities, then its basic LP relaxation is tight.\r\n\r\nOur third stop is matroid theory. Seymour’s decomposition theorem is a hallmark result in matroid theory, presenting a structural characterization of the class of regular matroids. We aim to formally verify Seymour’s theorem in Lean 4. First, we build a library for working with totally unimodular matrices. We define binary matroids and their standard representations, and we prove that they form a matroid in the sense how Mathlib defines matroids. We define regular matroids to be matroids for which there exists a full representation rational matrix that is totally unimodular, and we prove that all regular matroids are binary. We define 1-sum, 2-sum, and 3 sum of binary matroids as specific ways to compose their standard representation matrices. We prove that the 1-sum, the 2-sum, and the 3-sum of regular matroids are a regular matroid, which concludes the composition direction of the Seymour’s theorem. The (more difficult) decomposition direction remains unproved.\r\n\r\nIn the pursuit of truth, we focus on identifying the trusted code in each project and presenting it faithfully. We emphasize the readability and believability of definitions rather than choosing definitions that are easier to work with. In search for beauty, we focus on the philosophical framework of Roger Scruton, who emphasizes that beauty is not a mere decoration but, most importantly, beauty is the means for shaping our place in the world and a source of redemption, where it can be viewed as a substitute for religion.","lang":"eng"}],"supervisor":[{"id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87","full_name":"Kolmogorov, Vladimir","first_name":"Vladimir","last_name":"Kolmogorov"},{"full_name":"Blanchette, Jasmin","last_name":"Blanchette","first_name":"Jasmin"}],"day":"04","oa":1,"title":"Pursuit of truth and beauty in Lean 4 : Formally verified theory of grammars, optimization, matroids","alternative_title":["ISTA Thesis"],"year":"2026","doi":"10.15479/AT-ISTA-21393","publication_status":"published","file_date_updated":"2026-03-04T09:03:37Z","degree_awarded":"PhD","ddc":["511","000"],"date_updated":"2026-03-27T12:37:00Z","type":"dissertation","article_processing_charge":"No"},{"publication":"PRX Quantum","type":"journal_article","date_updated":"2026-03-30T06:09:28Z","PlanS_conform":"1","scopus_import":"1","ddc":["530"],"article_processing_charge":"Yes","article_type":"original","oa":1,"OA_type":"gold","day":"13","year":"2026","title":"Fragmentation, zero modes, and collective bound states in constrained models","volume":7,"article_number":"010352","language":[{"iso":"eng"}],"corr_author":"1","abstract":[{"lang":"eng","text":"Kinetically constrained models were originally introduced to capture slow relaxation in glassy systems, where dynamics are hindered by local constraints instead of energy barriers. 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.

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. Together, these findings reveal key aspects of the conformational dynamics and remodeling outcomes underlying BAF processing of TF-bound nucleosomes."}],"department":[{"_id":"AlMi"}],"date_created":"2026-03-30T11:58:48Z","citation":{"chicago":"Weiss, Joscha, Luca Vecchia, David Domjan, Simone Cavadini, Anton Sabantsev, Georg Kempf, Ganesh R.

Following fertilisation, the zygote divides asymmetrically to generate apical and basal lineages, establishing the apical–basal axis that defines future shoot and root poles. Genetic and molecular analyses of classical mutants including gnom, monopteros (mp), bodenlos (bdl) and topless revealed that localised auxin biosynthesis, directional transport and downstream transcriptional responses are central to apical–basal axis establishment and organ initiation. The main components of this regulation are polarly localised PIN auxin transporters and downstream modules involving MONOPTEROS and WUSCHEL-RELATED HOMEOBOX transcription factors. Advances in microscopy have transformed the study of Arabidopsis embryogenesis: fluorescence-compatible clearing reagents and three-dimensional reconstructions now permit quantitative analyses of cell geometry, division orientation, and cytoskeletal dynamics. Live ovule imaging setups with confocal laser scanning and multiphoton microscopes enable real-time observation of embryo development, while laser-assisted cell ablation can be used to probe cell-to-cell communication and fate plasticity. Together, these methodological breakthroughs position Arabidopsis embryos as a prime model for dissecting the chemical and biophysical cues that shape plant development.","lang":"eng"}],"corr_author":"1","OA_type":"hybrid","day":"11","oa":1,"title":"Imaging and genetic toolbox to study Arabidopsis embryogenesis","year":"2026","doi":"10.1111/nph.71072","publication_status":"epub_ahead","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1111/nph.71072"}],"date_updated":"2026-03-30T05:58:35Z","PlanS_conform":"1","type":"journal_article","publication":"New Phytologist","article_processing_charge":"Yes (via OA deal)","article_type":"original"},{"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1016/j.isci.2026.115192"}],"publication_status":"epub_ahead","doi":"10.1016/j.isci.2026.115192","volume":29,"title":"Distribution and functional significance of rodent cerebellar glycogen","year":"2026","OA_type":"gold","day":"17","oa":1,"abstract":[{"text":"The mammalian brain stores glucose, the main circulating energy substrate, as glycogen. In rodents, the cerebellum contains relatively high glycogen levels, yet its cellular and subcellular distribution remains poorly defined. Using monoclonal antibodies against glycogen, we examined its distribution in the mouse cerebellar cortex. Glycogen was predominantly localized to Bergmann glia (BG) processes in the molecular layer and was also detected in Purkinje cells (PCs), the principal cerebellar neurons. To assess the functional significance of cerebellar glycogen, we analyzed behavior in mice lacking glycogen synthase 1 (Gys1) in BG or PCs using a floxed Gys1 line. Gys1 deficiency in either PCs or GFAP-positive cells reduced anxiety-like behavior, whereas combined deletion caused PC degeneration and ataxia. These findings reveal a critical role for glycogen metabolism in both astrocytes and neurons in cerebellar function.","lang":"eng"}],"language":[{"iso":"eng"}],"article_number":"115192","article_type":"original","article_processing_charge":"Yes","date_updated":"2026-03-30T06:20:06Z","publication":"iScience","type":"journal_article","scopus_import":"1","pmid":1,"author":[{"last_name":"Akther","first_name":"Sonam","full_name":"Akther, Sonam"},{"full_name":"Lee, Ashley Bomin","last_name":"Lee","first_name":"Ashley Bomin"},{"full_name":"Konno, Ayumu","last_name":"Konno","first_name":"Ayumu"},{"full_name":"Asiminas, Antonis","last_name":"Asiminas","first_name":"Antonis"},{"last_name":"Vittani","first_name":"Marta","full_name":"Vittani, Marta"},{"full_name":"Mishima, Tsuneko","first_name":"Tsuneko","last_name":"Mishima"},{"first_name":"Hirokazu","last_name":"Hirai","full_name":"Hirai, Hirokazu"},{"full_name":"Meehan, Claire Francesca","last_name":"Meehan","first_name":"Claire Francesca"},{"last_name":"Duran","first_name":"Jordi","full_name":"Duran, Jordi"},{"full_name":"Guinovart, Joan","first_name":"Joan","last_name":"Guinovart"},{"last_name":"Ashida","first_name":"Hitoshi","full_name":"Ashida, Hitoshi"},{"full_name":"Morita, Tsuyoshi","last_name":"Morita","first_name":"Tsuyoshi"},{"last_name":"Baba","first_name":"Otto","full_name":"Baba, Otto"},{"orcid":"0000-0001-8761-9444","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","full_name":"Shigemoto, Ryuichi","first_name":"Ryuichi","last_name":"Shigemoto"},{"last_name":"Nedergaard","first_name":"Maiken","full_name":"Nedergaard, Maiken"},{"full_name":"Hirase, Hajime","first_name":"Hajime","last_name":"Hirase"}],"DOAJ_listed":"1","external_id":{"pmid":["41890976"]},"OA_place":"publisher","oa_version":"Published Version","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","acknowledgement":"This work was supported by the Novo Nordisk Foundation (NNFOC0058058, H.

Quadrupolar (ℓ = 2) mixed modes also contain information regarding internal dynamics but are very rarely characterised due to their low amplitude and the challenging identification of adjacent or overlapping rotationally split multiplets affected by near-degeneracy effects. We aim to extend the broadly used asymptotic seismic diagnostics beyond ℓ = 1 mixed modes by developing an analogue asymptotic description of ℓ = 2 mixed modes while explicitly accounting for near-degeneracy effects that distort their rotational multiplets. We have derived a new asymptotic formulation of near-degenerate mixed ℓ = 2 modes that describes off-diagonal terms representing the interaction between modes of adjacent radial orders. This formalism, expressed directly in the mixed-mode basis, provides analytical expressions for the near-degeneracy effects. We implemented the formalism within a global Bayesian mode-fitting framework for a direct fit of all ℓ = 0, 1, 2 modes in the power spectrum density. We were able to asymptotically model the asymmetric rotational splitting present in various radial orders of ℓ = 2 modes observed in young red giant stars without the need for any numerical stellar modelling. We applied our formalism to the Kepler target KIC 7341231, and it yielded core and envelope rotation rates consistent with previous numerical modelling while providing improved constraints from the global and model-independent approach. We also characterised the new target, KIC 8179973, measuring its rotation rate and mixed-mode parameters for the first time. As our framework relies on a direct global fit, it allows for much better precision on the asteroseismic parameters and rotation rate estimates than standard methods, yielding better constraints for rotation inversions. We have placed the first observational constraints on the asymptotic ℓ = 2 mixed-mode parameters (ΔΠ2, q2, and εg, 2), thus paving the way towards the use of asymptotic seismology beyond ℓ = 1 mixed modes.","lang":"eng"}],"corr_author":"1","day":"01","OA_type":"diamond","oa":1,"volume":707,"title":"Near-degeneracy effects in quadrupolar mixed modes: From an asymptotic description to data fitting","year":"2026","article_processing_charge":"No","article_type":"original","ddc":["520"],"scopus_import":"1","date_updated":"2026-04-07T09:01:44Z","PlanS_conform":"1","type":"journal_article","publication":"Astronomy and Astrophysics"},{"project":[{"_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","name":"IST-BRIDGE: International postdoctoral program","call_identifier":"H2020","grant_number":"101034413"}],"quality_controlled":"1","date_published":"2026-03-01T00:00:00Z","_id":"21657","publication_identifier":{"eissn":["1942-2466"]},"intvolume":"        18","issue":"3","date_created":"2026-04-05T22:01:31Z","department":[{"_id":"CaMu"}],"publisher":"Wiley","citation":{"ieee":"D.

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."}],"corr_author":"1","file_date_updated":"2026-04-07T09:11:23Z","ec_funded":1,"doi":"10.1029/2025MS005343","publication_status":"published"},{"date_created":"2026-04-05T22:01:32Z","department":[{"_id":"LiBu"}],"publisher":"Wiley","citation":{"apa":"Breton, S.

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."}]},{"intvolume":"         8","publication_identifier":{"issn":["2643-1564"]},"_id":"21660","quality_controlled":"1","project":[{"grant_number":"F100403","name":"Coherent Optical Metrology Beyond Electric-Dipole-Allowed Transitions","_id":"7c040762-9f16-11ee-852c-dd79eeee4ab3"}],"date_published":"2026-03-18T00:00:00Z","status":"public","month":"03","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"department":[{"_id":"MiLe"}],"date_created":"2026-04-05T22:01:32Z","citation":{"chicago":"Becker, A., Georgios Koutentakis, and P.

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.

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"}],"supervisor":[{"first_name":"Christoph","last_name":"Lampert","id":"40C20FD2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8622-7887","full_name":"Lampert, Christoph"}],"corr_author":"1","acknowledged_ssus":[{"_id":"ScienComp"}],"file_date_updated":"2026-02-27T10:25:41Z","doi":"10.15479/AT-ISTA-21198","publication_status":"published","type":"dissertation","date_updated":"2026-04-07T11:46:11Z","degree_awarded":"PhD","ddc":["005"],"article_processing_charge":"No"},{"file":[{"file_name":"2025_Fillmore_Christopher_Thesis.pdf","file_size":55954297,"checksum":"4c0889130095c31d4e5088c5b8dfd607","date_created":"2026-01-26T19:44:46Z","access_level":"open_access","relation":"main_file","creator":"cfillmor","content_type":"application/pdf","file_id":"21046","date_updated":"2026-01-30T11:40:09Z"},{"date_updated":"2026-01-26T19:46:20Z","file_id":"21047","content_type":"application/x-zip-compressed","creator":"cfillmor","relation":"source_file","access_level":"closed","date_created":"2026-01-26T19:46:20Z","checksum":"d69afb71d82ab98f856886126ee7303a","file_size":166080788,"file_name":"Thesis.zip"}],"acknowledgement":"The research presented in this thesis was funded by the DFG Collaborative Research\r\nCenter TRR 109, ‘Discretization in Geometry and Dynamics’.\r\n","has_accepted_license":"1","OA_place":"publisher","author":[{"last_name":"Fillmore","first_name":"Christopher D","full_name":"Fillmore, Christopher D","id":"35638A5C-AAC7-11E9-B0BF-5503E6697425"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","related_material":{"record":[{"status":"public","id":"20260","relation":"part_of_dissertation"},{"relation":"part_of_dissertation","id":"21050","status":"public"},{"relation":"part_of_dissertation","status":"public","id":"21051"}]},"oa_version":"Published Version","date_published":"2026-01-21T00:00:00Z","_id":"21021","publication_identifier":{"issn":["2663-337X"]},"department":[{"_id":"GradSch"},{"_id":"HeEd"},{"_id":"UlWa"}],"date_created":"2026-01-20T21:38:40Z","publisher":"Institute of Science and Technology Austria","citation":{"ieee":"C.

It considers how continuous manifolds relate to their discrete analogues, how topological structures evolve in persistence vineyards, and how tools from topological data analysis can illuminate problems in mathematical physics. 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"}],"corr_author":"1","language":[{"iso":"eng"}],"title":"Braiding vineyards","year":"2026","day":"02","oa":1,"publication_status":"draft","related_material":{"record":[{"id":"21056","status":"public","relation":"later_version"},{"id":"21021","status":"public","relation":"dissertation_contains"}]},"oa_version":"Preprint","doi":"10.48550/ARXIV.2504.11203","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","author":[{"last_name":" Chambers","first_name":"Erin","full_name":" Chambers, Erin"},{"first_name":"Christopher D","last_name":"Fillmore","id":"35638A5C-AAC7-11E9-B0BF-5503E6697425","full_name":"Fillmore, Christopher D"},{"orcid":"0000-0002-6862-208X","id":"2D04F932-F248-11E8-B48F-1D18A9856A87","full_name":"Stephenson, Elizabeth R","last_name":"Stephenson","first_name":"Elizabeth R"},{"id":"307CFBC8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-7472-2220","full_name":"Wintraecken, Mathijs","last_name":"Wintraecken","first_name":"Mathijs"}],"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2504.11203","open_access":"1"}],"external_id":{"arxiv":["2504.11203"]},"arxiv":1,"OA_place":"repository","_id":"21051","date_published":"2026-01-02T00:00:00Z","date_updated":"2026-04-07T11:42:48Z","type":"preprint","publication":"arXiv","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"status":"public","month":"01","article_processing_charge":"No","citation":{"ama":"Chambers E, Fillmore CD, Stephenson ER, Wintraecken M.

Floquet engineering, the coherent dressing of quantum states with periodic non-resonant optical fields, has become an important strategy for quantum control. 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. We use resonant third-harmonic generation to quantify ultrafast π/2 rotations on the Bloch sphere spanned by these exciton states. Our work advances the quest towards programmable control of correlated states and exciton-based quantum sensing.","lang":"eng"}],"language":[{"iso":"eng"}],"year":"2026","title":"Quantum control of Hubbard excitons","oa":1,"OA_type":"green","day":"09","month":"03","status":"public","publisher":"Springer Nature","citation":{"chicago":"Baykusheva, Denitsa Rangelova, Deven Carmichael, Clara S.

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⊙.","lang":"eng"}],"day":"01","OA_type":"gold","oa":1,"title":"The White Dwarf initial–final mass relation from open clusters in Gaia DR3","volume":996,"year":"2026","article_processing_charge":"Yes","article_type":"original","ddc":["520"],"scopus_import":"1","PlanS_conform":"1","date_updated":"2026-04-13T08:39:39Z","type":"journal_article","publication":"The Astrophysical Journal"},{"_id":"21699","scopus_import":"1","date_updated":"2026-04-13T11:26:08Z","publication":"arXiv","type":"preprint","date_published":"2026-01-14T00:00:00Z","status":"public","month":"01","article_processing_charge":"No","date_created":"2026-04-09T09:10:41Z","citation":{"ieee":"J.

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."}],"day":"14","OA_type":"green","oa":1,"extern":"1","title":"Wavefront engineering for scintillation-based imaging","year":"2026","oa_version":"Preprint","doi":"10.48550/arXiv.2601.09830","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"submitted","OA_place":"repository","author":[{"full_name":"Chen, Joshua","last_name":"Chen","first_name":"Joshua"},{"full_name":"Vaidya, Sachin","last_name":"Vaidya","first_name":"Sachin"},{"first_name":"Simo","last_name":"Pajovic","full_name":"Pajovic, Simo"},{"full_name":"Choi, Seou","first_name":"Seou","last_name":"Choi"},{"last_name":"Michaels","first_name":"William","full_name":"Michaels, William"},{"full_name":"Louis Martin-Monier, Louis Martin-Monier","first_name":"Louis Martin-Monier","last_name":"Louis Martin-Monier"},{"full_name":"Hu, Juejun","first_name":"Juejun","last_name":"Hu"},{"last_name":"Cogswell","first_name":"Carol","full_name":"Cogswell, Carol"},{"first_name":"Charles","last_name":"Roques-Carmes","full_name":"Roques-Carmes, Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82"},{"first_name":"Marin","last_name":"Soljačić","full_name":"Soljačić, Marin"}],"main_file_link":[{"url":" https://doi.org/10.48550/arXiv.2601.09830","open_access":"1"}],"arxiv":1,"external_id":{"arxiv":["2601.09830"]}}]
