These solutions are evolving varifolds, just as in Brakke's formulation, but are coupled to the phase volumes by a simple transport equation. First, we show that, in the exact same setup as in Ilmanen's proof [J. Differential Geom. 38, 417-461, (1993)], any limit point of solutions to the Allen-Cahn equation is a varifold solution in our sense. Second, we prove that any calibrated flow in the sense of Fischer et al. [arXiv:2003.05478] - and hence any classical solution to mean curvature flow-is unique in the class of our new varifold solutions. This is in sharp contrast to the case of Brakke flows, which a priori may disappear at any given time and are therefore fatally non-unique. Finally, we propose an extension of the solution concept to the multi-phase case which is at least guaranteed to satisfy a weak-strong uniqueness principle."}],"publisher":"International Press of Boston","keyword":["Mean curvature flow","gradient flows","varifolds","weak solutions","weak-strong uniqueness","calibrated geometry","gradient-flow calibrations"],"OA_place":"repository","_id":"10011","page":"209-268","scopus_import":"1","date_created":"2021-09-13T12:17:10Z","project":[{"name":"Bridging Scales in Random Materials","grant_number":"948819","call_identifier":"H2020","_id":"0aa76401-070f-11eb-9043-b5bb049fa26d"}],"volume":130,"title":"A new varifold solution concept for mean curvature flow: Convergence of the Allen-Cahn equation and weak-strong uniqueness","citation":{"mla":"Hensel, Sebastian, and Tim Laux. “A New Varifold Solution Concept for Mean Curvature Flow: Convergence of the Allen-Cahn Equation and Weak-Strong Uniqueness.” Journal of Differential Geometry, vol. 130, International Press of Boston, 2025, pp. 209–68, doi:10.4310/jdg/1747065796.","ista":"Hensel S, Laux T. 2025.

MLS is a scalable secure group messaging protocol expected to run more efficiently compared to the Signal protocol at scale, while offering a similar level of strong security. Even though MLS has undergone extensive examination by researchers, the majority of the works have focused on confidentiality.\r\n\r\nIn this work, we focus on the authenticity of the application messages exchanged in MLS. Currently, MLS authenticates every application message with an EdDSA signature and while manageable, the overhead is greatly amplified in the post-quantum setting as the NIST-recommended Dilithium signature results in a 40x increase in size. We view this as an invitation to explore new authentication modes that can be used instead. We start by taking a systematic view on how application messages are authenticated in MLS and categorize authenticity into four different security notions. We then propose several authentication modes, offering a range of different efficiency and security profiles. For instance, in one of our modes, COSMOS++, we replace signatures with one-time tokens and a MAC tag, offering roughly a 75x savings in the post-quantum communication overhead. While this comes at the cost of weakening security compared to the authentication mode used by MLS, the lower communication overhead seems to make it a worthwhile trade-off with security.","lang":"eng"}],"_id":"20668","OA_place":"publisher","date_created":"2025-11-23T23:01:40Z","scopus_import":"1","page":"6699-6716"},{"external_id":{"arxiv":["2504.07752","2504.07770"]},"doi":"10.4230/LIPIcs.SoCG.2025.75","file":[{"checksum":"a8f7feb1aa3b896e31195841a989d622","relation":"main_file","access_level":"open_access","file_id":"20015","file_size":952807,"content_type":"application/pdf","success":1,"date_created":"2025-07-14T07:11:04Z","date_updated":"2025-07-14T07:11:04Z","file_name":"2025_LIPIcs.SoCG_Streltsova.pdf","creator":"dernst"}],"author":[{"last_name":"Streltsova","full_name":"Streltsova, Elizaveta","first_name":"Elizaveta","id":"57a170da-dc96-11ea-b7c8-ab3565071bf7"},{"first_name":"Uli","id":"36690CA2-F248-11E8-B48F-1D18A9856A87","last_name":"Wagner","orcid":"0000-0002-1494-0568","full_name":"Wagner, Uli"}],"oa_version":"Published Version","alternative_title":["LIPIcs"],"publication_status":"published","article_number":"75","intvolume":" 332","das_tickbox":"1","arxiv":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","OA_type":"gold","article_processing_charge":"Yes","conference":{"start_date":"2025-06-23","name":"SoCG: Symposium on Computational Geometry","end_date":"2025-06-27","location":"Kanazawa, Japan"},"volume":332,"title":"Levels in arrangements: Linear relations, the g-matrix, and applications to crossing numbers","citation":{"chicago":"Streltsova, Elizaveta, and Uli Wagner. “Levels in Arrangements: Linear Relations, the g-Matrix, and Applications to Crossing Numbers.” In 41st International Symposium on Computational Geometry, Vol. 332.

We prove this conjecture in the case n = d+4. By Gale duality, this implies the following result about crossing numbers: In every spherical arc drawing of K_n in S² (given by a set V ⊂ S² of n unit vectors connected by spherical arcs), the number of crossings is at least 1/4 ⌊n/2⌋ ⌊(n-1)/2⌋ ⌊(n-2)/2⌋ ⌊(n-3)/2⌋. This lower bound is attained if every open linear halfspace contains at least ⌊(n-2)/2⌋ of the vectors in V.\r\nMoreover, we determine the space of all linear and affine relations that hold between the face numbers of levels in simple arrangements of n hemispheres in S^d. This completes a long line of research on such relations, answers a question posed by Andrzejak and Welzl in 2003, and generalizes the classical fact that the Dehn-Sommerville relations generate all linear relations between the face numbers of simple polytopes (which correspond to the 0-level).\r\nTo prove these results, we introduce the notion of the g-matrix, which encodes the face numbers of levels in an arrangement and generalizes the classical g-vector of a polytope."}],"publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik"},{"article_number":"L050402","publication_status":"published","issue":"5","das_tickbox":"1","intvolume":" 111","arxiv":1,"external_id":{"isi":["001501941500006"],"arxiv":["2405.08065"]},"related_material":{"record":[{"relation":"research_data","status":"public","id":"22142"}]},"file":[{"access_level":"open_access","relation":"main_file","file_id":"19755","file_size":571784,"content_type":"application/pdf","checksum":"b83295a8f597b7781d8e7bfa3b393b42","success":1,"date_updated":"2025-05-28T09:16:03Z","date_created":"2025-05-28T09:16:03Z","file_name":"2025_PhysReviewA_Kun.pdf","creator":"dernst"}],"author":[{"full_name":"Kun, Daniel","last_name":"Kun","first_name":"Daniel"},{"full_name":"Strömberg, Karl T","last_name":"Strömberg","id":"68011cd2-da32-11ee-a930-b2774c7aba5f","first_name":"Karl T"},{"last_name":"Spagnolo","full_name":"Spagnolo, Michele","first_name":"Michele"},{"last_name":"Dakić","full_name":"Dakić, Borivoje","first_name":"Borivoje"},{"first_name":"Lee A.","last_name":"Rozema","full_name":"Rozema, Lee A."},{"first_name":"Philip","full_name":"Walther, Philip","last_name":"Walther"}],"researchdata_availability":"yes","doi":"10.1103/PhysRevA.111.L050402","oa_version":"Published Version","oa":1,"status":"public","month":"05","publication":"Physical Review A","isi":1,"dataavailabilitystatement":"Data that support the findings of this study are openly available at Zenodo.","quality_controlled":"1","ddc":["530"],"scopus_import":"1","date_created":"2025-05-25T22:16:54Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"OA_place":"publisher","_id":"19733","publisher":"American Physical Society","abstract":[{"lang":"eng","text":"One of the most striking quantum phenomena is superposition, where one particle simultaneously inhabits different states. Most methods to verify coherent superposition are indirect, in that they require the distinct states to be recombined. Here, we adapt an xor game, in which a “test” photon is placed in a superposition of two orthogonal spatial modes, and each mode is sent to separated parties who perform local measurements on their modes without reinterfering the original modes. We show that by using a second identical “measurement” photon the parties are nonetheless able to verify if the test photon was placed in coherent superposition of the two spatial modes. We then turn this game into a resource-efficient verification scheme, obtaining a confidence that the particle is superposed which approaches unity exponentially fast. We demonstrate our scheme using a single photon, obtaining a 99% confidence that the particle is superposed with only 37 copies. Our work shows the utility of xor games to verify quantum resources, allowing us to efficiently detect quantum superposition without reinterfering the superposed modes."}],"acknowledgement":"This project has received funding from the European Union's Horizon 2020 and Horizon Europe research and innovation programmes under Grant Agreements No. 899368 (EPIQUS) and No. 101135288 (EPIQUE), the Marie Skłodowska-Curie Grant Agreement No. 956071 (AppQInfo), and the QuantERA II Programme under Grant Agreement No. 101017733 (PhoMemtor).

Like the summary of the first workshop (Abend et al. in AVS Quantum Sci. 6:024701, 2024), this document records a critical milestone for the international atom interferometry community. It documents our concerted efforts to evaluate progress, address emerging challenges, and refine strategic directions for future large-scale atom interferometry projects. Our commitment to collaboration is manifested by the integration of diverse expertise and the coordination of international resources, all aimed at advancing the frontiers of atom interferometry physics and technology, as set out in a Memorandum of Understanding signed by over 50 institutions (Memorandum of Understanding for the Terrestrial Very Long Baseline Atom Interferometer Study)."}],"article_type":"review","publisher":"Springer Nature","isi":1,"oa":1,"status":"public","month":"04","publication":"EPJ Quantum Technology","ddc":["530"],"quality_controlled":"1","dataavailabilitystatement":"No datasets were generated or analysed during the current study.","doi":"10.1140/epjqt/s40507-025-00344-3","author":[{"last_name":"Abdalla","full_name":"Abdalla, Adam","first_name":"Adam"},{"full_name":"Abe, Mahiro","last_name":"Abe","first_name":"Mahiro"},{"full_name":"Abend, Sven","last_name":"Abend","first_name":"Sven"},{"full_name":"Abidi, Mouine","last_name":"Abidi","first_name":"Mouine"},{"first_name":"Monika","last_name":"Aidelsburger","full_name":"Aidelsburger, Monika"},{"full_name":"Alibabaei, Ashkan","last_name":"Alibabaei","first_name":"Ashkan"},{"last_name":"Allard","full_name":"Allard, Baptiste","first_name":"Baptiste"},{"last_name":"Antoniadis","full_name":"Antoniadis, John","first_name":"John"},{"first_name":"Gianluigi","last_name":"Arduini","full_name":"Arduini, Gianluigi"},{"full_name":"Augst, Nadja","last_name":"Augst","first_name":"Nadja"},{"first_name":"Philippos","last_name":"Balamatsias","full_name":"Balamatsias, Philippos"},{"full_name":"Balaž, Antun","last_name":"Balaž","first_name":"Antun"},{"full_name":"Banks, Hannah","last_name":"Banks","first_name":"Hannah"},{"last_name":"Barcklay","full_name":"Barcklay, Rachel L.","first_name":"Rachel L."},{"full_name":"Barone, Michele","last_name":"Barone","first_name":"Michele"},{"last_name":"Barsanti","full_name":"Barsanti, Michele","first_name":"Michele"},{"full_name":"Bason, Mark G.","last_name":"Bason","first_name":"Mark G."},{"first_name":"Angelo","full_name":"Bassi, Angelo","last_name":"Bassi"},{"full_name":"Bayle, Jean Baptiste","last_name":"Bayle","first_name":"Jean Baptiste"},{"first_name":"Charles F.A.","full_name":"Baynham, Charles F.A.","last_name":"Baynham"},{"last_name":"Beaufils","full_name":"Beaufils, Quentin","first_name":"Quentin"},{"last_name":"Beldjoudi","full_name":"Beldjoudi, Sélyan","first_name":"Sélyan"},{"last_name":"Belić","full_name":"Belić, Aleksandar","first_name":"Aleksandar"},{"first_name":"Shayne","full_name":"Bennetts, Shayne","last_name":"Bennetts"},{"full_name":"Bernabeu, Jose","last_name":"Bernabeu","first_name":"Jose"},{"full_name":"Bertoldi, Andrea","last_name":"Bertoldi","first_name":"Andrea"},{"first_name":"Clara","last_name":"Bigard","full_name":"Bigard, Clara"},{"first_name":"N.

Traditional QKD protocols require extensive noise compensation, hindering their industrial scalability and lowering the achievable key rates. Alternative protocols encode logical qubits in noise-resilient states but at the cost of using many physical qubits, increasing susceptibility to loss and limiting transmission distance. In this work, we introduce a logical-qubit encoding that uses antisymmetric Bell states in the continuous photonic degrees of freedom, frequency and time. By leveraging the continuous space, we overcome this noise-loss robustness trade-off by minimizing the number of photons per logical qubit while optimizing the encoding resilience over noise fluctuations. We analyze the security of our encoding and demonstrate its robustness compared to existing state-of-the-art protocols. This approach provides a path toward scalable, efficient QKD implementations under realistic noise conditions.","lang":"eng"}],"acknowledgement":"We thank B. Baragiola, A. Boubriak, M. Clark, M.

Up to an adequate normalisation, it should converge, when the class of the sections goes arbitrarily far from the boundary of the dual of the effective cone, to an effective element given by a motivic Euler product. Such a principle can be seen as an analogue for rational curves of the Batyrev-Manin-Peyre principle for rational points.\r\n The central tool of this article is the property of equidistribution of curves. We show that this notion does not depend on the choice of a model of the generic fibre, and that equidistribution of curves holds for smooth projective split toric varieties. As an application, we study the Batyrev-Manin-Peyre principle for curves on a certain kind of twisted products.","lang":"eng"}],"article_type":"original","acknowledgement":"I am very grateful to my Ph.D. advisor Emmanuel Peyre for all the remarks and suggestions he made during the writing of this article.
