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."}],"oa":1,"day":"02","year":"2026","title":"Braiding vineyards","month":"01","article_processing_charge":"No","status":"public","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)"},"date_created":"2026-01-27T14:41:44Z","department":[{"_id":"HeEd"}],"citation":{"chicago":"Chambers, Erin, Christopher D Fillmore, Elizabeth R Stephenson, and Mathijs Wintraecken. “Braiding Vineyards.” <i>ArXiv</i>, n.d. <a href=\"https://doi.org/10.48550/ARXIV.2504.11203\">https://doi.org/10.48550/ARXIV.2504.11203</a>.","mla":"Chambers, Erin, et al. “Braiding Vineyards.” <i>ArXiv</i>, doi:<a href=\"https://doi.org/10.48550/ARXIV.2504.11203\">10.48550/ARXIV.2504.11203</a>.","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. We use resonant third-harmonic generation to quantify ultrafast π/2 rotations on the Bloch sphere spanned by these exciton 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.

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_number":"2601.09830","language":[{"iso":"eng"}],"author":[{"full_name":"Chen, Joshua","first_name":"Joshua","last_name":"Chen"},{"full_name":"Vaidya, Sachin","first_name":"Sachin","last_name":"Vaidya"},{"last_name":"Pajovic","first_name":"Simo","full_name":"Pajovic, 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"},{"first_name":"Juejun","last_name":"Hu","full_name":"Hu, Juejun"},{"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":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.2601.09830"}],"external_id":{"arxiv":["2601.09830"]},"arxiv":1,"OA_place":"repository","publication_status":"submitted","oa_version":"Preprint","doi":"10.48550/arXiv.2601.09830","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2026-01-14T00:00:00Z","date_updated":"2026-04-13T11:26:08Z","publication":"arXiv","type":"preprint","scopus_import":"1","_id":"21699","citation":{"ieee":"J.

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.

We present a photonic integrated circuit that enables the generation and analysis of arbitrary polarization states. The device provides reconfigurable access to the full polarization degree of freedom of coherent light within a single integrated platform. We experimentally demonstrate arbitrary polarization state generation spanning the Poincare sphere, as well as Stokes vector measurement on chip. Unlike conventional Stokes measurements that rely on direct detection, polarization analysis utilizing this architecture is intrinsically non-destructive, preserving the optical signal for further optical domain processing. The devices are fabricated in a commercial foundry using CMOS-compatible processes, enabling scalable and reproducible integration. By combining polarization generation and analysis in a compact and stable photonic circuit, this work eliminates the need for external polarization optics and provides a foundation for robust, polarization-enabled photonic integrated systems."}],"extern":"1","oa":1,"OA_type":"green","day":"19","year":"2026","title":"Integrated photonic polarization synthesizer and analyzer"},{"acknowledgement":"We would like to thank Elizabeth Marin, Anna Kicheva, Igor Adameyko, and James Briscoe as\r\nwell as members of the Sweeney and Hippemeyer labs and SFB consortium for comments on\r\nthe manuscript.

During development, eleven spinal cord progenitor domains generate an equivalent number of cardinal neuron types. How progenitor domains, individual progenitors, and post-mitotic diversity relate is still unknown. 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. These findings redefine spinal cord development as a process in which lineage variability — rather than rigid progenitor identity — drives the generation of cellular diversity.","lang":"eng"}],"corr_author":"1","acknowledged_ssus":[{"_id":"PreCl"},{"_id":"Bio"}],"language":[{"iso":"eng"}],"year":"2026","title":"Lineage origin of spinal cord cell type diversity","oa":1,"OA_type":"green","day":"16","publication_status":"submitted","doi":"10.64898/2026.02.12.705305","main_file_link":[{"open_access":"1","url":"https://doi.org/10.64898/2026.02.12.705305"}],"ddc":["570"],"type":"preprint","publication":"bioRxiv","date_updated":"2026-04-14T08:16:55Z","article_processing_charge":"No"},{"department":[{"_id":"JoFi"},{"_id":"GradSch"}],"date_created":"2026-03-15T23:01:35Z","citation":{"short":"S.

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"}],"corr_author":"1"},{"doi":"10.1007/978-3-032-07035-7_8","publication_status":"published","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2505.14891"}],"language":[{"iso":"eng"}],"corr_author":"1","abstract":[{"text":"The Nakamoto consensus protocol underlying the Bitcoin blockchain uses proof of work as a voting mechanism.

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.

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.

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"}],"language":[{"iso":"eng"}],"article_number":"L42","article_type":"original","article_processing_charge":"Yes","type":"journal_article","publication":"The Astrophysical Journal Letters","date_updated":"2026-04-16T06:26:18Z","scopus_import":"1","ddc":["520"]},{"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)"},"month":"03","status":"public","citation":{"ieee":"N.

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"}],"language":[{"iso":"eng"}],"article_type":"original","article_processing_charge":"Yes (via OA deal)","PlanS_conform":"1","date_updated":"2026-04-16T06:20:23Z","type":"journal_article","publication":"Nature Physics","ddc":["570"],"scopus_import":"1","author":[{"first_name":"Daniel B","last_name":"Grober","id":"c692f879-718d-11ee-81f0-da7caa79c783","full_name":"Grober, Daniel B"},{"last_name":"Dhar","first_name":"Tanumoy","full_name":"Dhar, Tanumoy"},{"full_name":"Saintillan, David","last_name":"Saintillan","first_name":"David"},{"first_name":"Jérémie A","last_name":"Palacci","id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","full_name":"Palacci, Jérémie A","orcid":"0000-0002-7253-9465"}],"OA_place":"publisher","oa_version":"Published Version","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","has_accepted_license":"1","acknowledgement":"We thank E.

The probe is highly selective for H2O2, showing no fluorescence enhancement with other ROS. RN is synthesised in a one-pot chemical reaction using rhodamine 6G (R6G) and 4,7,10-trioxa-1,13-tridecanediamine (TTDA). H2O2 detection in pre-treated milk samples proves its real-world viability.

The evolutionary success of these populations is fundamentally dictated by the organization of genetic variation—the genomic architecture—in the face of severe demographic constraints, such as the founder effects and genetic bottlenecks that frequently accompany colonization. A central question in evolutionary biology is whether rapid adaptation relies on major-effect loci, such as chromosomal inversions, or on many small-effect loci dispersed across the genome. Furthermore, the genomic architecture strongly influences the extent to which evolutionary outcomes are predictable. Using introduced populations of the marine snail, Littorina saxatilis, as a model, this thesis investigates how genetic variation and genomic structure drive adaptation following introduction. We employed a population genomics approach on experimentally and accidentally introduced populations to dissect the specific genomic features that underpin divergence in newly colonized environments.\r\n\r\nIn Chapter 2, we tested the predictability of local adaptation through an uncommon 30-year transplant experiment in nature. By distinguishing allele and chromosomal inversion frequency changes from neutral expectations, we found that evolutionary change was highly predictable at the macro-scale (phenotypes and chromosomal inversions), but less robust at the level of individual collinear loci. This result demonstrates that evolution can be predictable when a population possesses sufficient standing genetic variation (SGV), with chromosomal inversions acting as key integrated units that facilitate a rapid response to selection. Building on this, Chapter 3 applied whole-genome sequencing to three accidentally introduced populations (Venice, San Francisco, and Redwood City) to investigate their likely source and genomic patterns of divergence. We identified genomic regions of remarkable divergence potentially associated with local adaptation, and likely fuelled by SGV, while explicitly acknowledging the difficulty in disentangling selection signals from the genome-wide effects of demographic processes. Furthermore, we found that the divergence patterns relied extensively on the collinear genome in these introduced populations, and less clearly on the chromosomal inversions. This observation contrasts with local adaptation observed in the experimental system that relied on both collinear loci and highly selected chromosomal inversions, highlighting how demographic history and genomic architecture influence the detectable signature of local adaptation.\r\n\r\nA major limitation to conducting large-scale comparative evolutionary studies is the lack of data standardization, which prevents the integration of community knowledge and high-resolution environmental and genetic data. Chapter 4 addresses this by developing a community database for the Littorina system. This platform implements standardized protocols for the integration of diverse phenotypic and environmental data from multiple Littorina species. Likewise, the platform also centralizes the availability of associated genomic data through links to external repositories. This database represents a crucial tool to test complex, large-scale evolutionary hypotheses.\r\n\r\nCollectively, this thesis strongly reinforces the fundamental importance of SGV as the raw material for successful local adaptation, a conclusion supported by evidence in both experimental and accidental introductions. Furthermore, this work highlights the critical role of the genomic architecture—specifically chromosomal inversions—in driving the predictability and effectiveness of adaptive responses. Our findings underscore how the interplay between SGV and genomic architecture dictates the trajectory and detectability of evolution in colonizing populations, while simultaneously providing a necessary tool to advance comparative evolutionary genomics in emerging model organisms.","lang":"eng"}],"supervisor":[{"orcid":"0000-0002-8548-5240","full_name":"Barton, Nicholas H","id":"4880FE40-F248-11E8-B48F-1D18A9856A87","last_name":"Barton","first_name":"Nicholas H"},{"first_name":"Anja M","last_name":"Westram","orcid":"0000-0003-1050-4969","full_name":"Westram, Anja M","id":"3C147470-F248-11E8-B48F-1D18A9856A87"}],"corr_author":"1","language":[{"iso":"eng"}],"year":"2026","alternative_title":["ISTA Thesis"],"title":"The genomic architecture of local adaptation in introduced populations","oa":1,"day":"16","article_processing_charge":"No","ddc":["576"],"degree_awarded":"PhD","type":"dissertation","date_updated":"2026-04-16T12:20:37Z","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","oa_version":"Published Version","related_material":{"record":[{"relation":"research_data","status":"public","id":"18498"},{"status":"public","id":"18491","relation":"part_of_dissertation"}]},"author":[{"id":"ae681a14-dc74-11ea-a0a7-c6ef18161701","full_name":"Garcia Castillo, Diego Fernando","first_name":"Diego Fernando","last_name":"Garcia Castillo"}],"OA_place":"publisher","file":[{"file_id":"20996","date_updated":"2026-01-16T12:25:13Z","creator":"dgarciac","content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document","date_created":"2026-01-16T12:25:13Z","access_level":"closed","relation":"source_file","file_name":"2026_Garcia_Diego_Thesis.docx","checksum":"841f1bc073d667125729b2a017f8c37a","file_size":22456421},{"date_created":"2026-01-16T12:25:13Z","relation":"main_file","access_level":"open_access","file_size":9556719,"success":1,"checksum":"a1f33d4f183ce7072eee42a6ccf5340b","file_name":"2026_Garcia_Diego_Thesis.pdf","date_updated":"2026-01-16T12:25:13Z","file_id":"20997","creator":"dgarciac","content_type":"application/pdf"},{"creator":"dgarciac","content_type":"application/x-compressed","file_id":"20998","date_updated":"2026-01-16T13:08:14Z","file_name":"2026_DiegoGarcia_LittorinaDB Source Code and Protocols.rar","file_size":54491433,"checksum":"98a80691067174c30fe53f38ce7344e6","date_created":"2026-01-16T13:08:14Z","description":"Source code of the PostgreSQL database, front-end and back-end of the LittorinaDB web application developed as a product of the 4th chapter of the thesis.","access_level":"closed","relation":"supplementary_material"},{"content_type":"application/x-compressed","creator":"dgarciac","file_id":"20999","date_updated":"2026-01-16T13:08:14Z","file_name":"2026_DiegoGarcia_Thesis-Supplementary_Material.rar","file_size":7982811,"checksum":"99a3cab2fa36666b9a92eefc27d586da","access_level":"open_access","relation":"supplementary_material","date_created":"2026-01-16T13:08:14Z"},{"date_updated":"2026-01-16T13:08:59Z","file_id":"21000","creator":"dgarciac","content_type":"text/plain","date_created":"2026-01-16T13:08:59Z","access_level":"open_access","relation":"supplementary_material","file_name":"README.txt","file_size":732,"checksum":"255fdf56b2932c46bf27c63aa6106a4f"}],"acknowledgement":"I acknowledge the funding agencies 1Norwegian Research Council RCN project 315287.\r\n2The FIASCO project \"Illuminating range shifts through evolutionary FIASCO: contrasting\r\nFaIling And Successful ColOnizations in replicated wild populations\", funded by the\r\nEuropean Union - Next Generation EU (Piano Nazionale di Ripresa e Resilienza - MUR\r\ncode: P202229JBC, CUP: C53D23007100001). 3Ecotypic formation in Littorina saxatilis\r\nin the Western Atlantic and comparisons across the North Atlantic.

We showcase the potential of ImpFab by fabricating three-dimensional photonic crystals and quasicrystals, as well as demonstrating optical structures with spatially modulated unit cell material properties.

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."}],"day":"18","OA_type":"gold","extern":"1","oa":1,"volume":12,"title":"Experimental observation of energy-band Riemann surface","year":"2026"}]
