However, this prediction stands in stark contrast to observations, where only a few per cent of CVs are found in this evolutionary phase. A potential solution to this discrepancy is that a magnetic field emerges from within the white dwarf after the system has reached the period minimum. The transfer of angular momentum from the spin of the white dwarf into the orbit then pushes the two stars apart, detaching them for potentially billions of years. Here we present the discovery of ZTF J021804.16+071152.93, a detached 0.69 +- 0.01 M, 19 MG magnetic white dwarf plus 37 +- 5MJup brown dwarf binary with an orbital period of 1.7 h. The kinematics of the system indicate that it is a high probability member of the Galactic thick disc. However, this strongly disagrees with the much younger age of the system obtained from the white dwarf parameters, implying that the system may have been accreting in the past. This system is therefore consistent with having detached as a result of the emergence of the magnetic field of the white dwarf when the system was still mass transferring, and may represent the ultimate fate for many (perhaps even most) CVs.","lang":"eng"}],"author":[{"first_name":"S.

Ensembles of these singularities exhibit distance correlations resembling particles in liquids5,6,7,8, extensively studied for their role in exotic material phases9,10,11. By contrast, the full correlations in phase space that govern the system evolution have remained unexplored and experimentally inaccessible. Here we directly measure the ultrafast dynamics of optical singularity ensembles, capturing their full phase-space correlations, presenting the joint distance–velocity distribution. Our observations show a breakdown of the particle-singularity analogy12: phase singularities accelerate towards formally divergent velocities in the moment before annihilation7,13,14, indicated by measurements of velocities exceeding the speed of light. These apparent superluminal velocities are paradoxically amplified by the slow group velocity of hyperbolic phonon polaritons in our material platform, hexagonal boron nitride membranes15,16,17,18,19. We demonstrate these phenomena using combined hardware and algorithmic advances in ultrafast electron microscopy18,20,21,22,23,24,25, achieving spatial and temporal resolutions, each an order of magnitude below the polaritonic wavelength and cycle period.

A variety of models with distinct complexity and data requirements have been developed and widely used to simulate melt under debris at different sites and scales, but their skills have never been compared. As part of the activities of the International Association of Cryospheric Sciences (IACS) Debris Covered Glacier Working Group, we present an intercomparison exercise aimed at advancing our understanding of model skills in simulating ice melt under a debris layer. We compare 15 models with different complexity at nine sites in the European Alps, Caucasus, Chilean Andes, Nepalese Himalaya and the Southern Alps of New Zealand, over one melt season. We run the models with measured meteorological data from automatic weather stations and estimated or measured debris properties. We consider four main model categories: (i) energy balance models that calculate melt by solving the physics of heat transfer to the debris layer, but require a high amount of input data; (ii) a simplified energy balance model; (iii) enhanced temperature-index models; and (iv) simple empirical temperature-index models that have been extensively used given their low data requirement but require calibration of their empirical parameters. Model performance is evaluated using on-site measurements of sub-debris melt (for all models) and surface temperature (for models based on the surface energy balance). Our results show that physically-based energy balance models and empirical temperature-index models perform in a distinct manner. At one end of the spectrum, simple temperature-index models are accurate when recalibrated or when using site-specific literature parameters, and show poor results when parameters are uncalibrated. At the other end, energy balance models show a range of performance: the most accurate energy balance models are those with the highest degree of complexity at the atmosphere-debris interface. An important data gap emerged from our experiment: the poor performance of all models at three sites was related to the poor knowledge of debris properties, and specifically of thermal conductivity. Future work should focus on both: (i) consistent data acquisition to evaluate existing models and support new model developments; (ii) advancing models by accounting for processes such as debris-snow interactions, moisture in the debris and refreezing. We suggest that a systematic effort of model development using a common model framework could be carried out in phase II of the Working Group."}],"oa_version":"Published Version","OA_place":"publisher","ddc":["550"],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)"},"title":"DCG-MIP: The debris-covered glacier melt model intercomparison experiment","status":"public","date_updated":"2026-05-18T06:12:56Z","volume":20},{"OA_place":"publisher","ddc":["540"],"oa_version":"Published Version","date_updated":"2026-05-18T06:59:10Z","volume":8,"title":"Photoacid‐mediated controllable gelation in a chemical reaction cycle","tmp":{"name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","image":"/images/cc_by_nc.png","short":"CC BY-NC (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode"},"status":"public","day":"06","date_created":"2026-05-07T08:51:01Z","citation":{"ieee":"A.

After volumetric segmentation of the liver and spleen on CT, Bayesian parameter optimization was used for selection of extracted features and hyperparameter tuning in random forest or elastic net models. Prediction accuracy was evaluated using Pearson correlation coefficients of predicted (’radio-HVPG’) and invasive HVPG. Discrimination between relevant HVPG cut-offs was determined by receiver operating characteristic (ROC) analysis. The predictive value of radio-HVPG and invasive-HVPG for LRE was compared using Cox regression models.\r\n\r\nResults: Radio-HVPG, predicted by an optimized random forest model based on 74 selected CT features, correlated with invasive-HVPG and detected clinically significant portal hypertension (CSPH: HVPG ≥ 10 mmHg) on the internal (Pearson r = 0.63, AUC 0.89 [95% CI: 0.81–0.96]) and external (Pearson r = 0.62, AUC 0.80 [95% CI: 0.64–0.91]) validation cohorts.

However, the frequency response under sinusoidal (AC) drivings offers rich insights into the time-dependent transport mechanisms. Inspired by recent electrochemical approaches, we investigate the couplings between ionic and electronic transport under AC driving. We show that conduction electrons of the channel walls participate in ionic current via capacitive electrochemical coupling, defining a critical frequency and length scale where electron-dominated conductivity emerges. We further analyze how electron–ion coupling modifies electro-osmotic flows and demonstrate that fluctuation-induced momentum transfer between the electrolyte and wall electrons produces distinct AC transport signatures, depending on the charge carrier polarity. Altogether, we establish a frequency-dependent transport matrix that couples ionic, electronic, and hydrodynamic flows. These findings establish AC nanofluidic transport as a powerful probe of interfacial phenomena under confinement and suggest new directions for engineering nanofluidic functionalities through electron–electrolyte coupling.","lang":"eng"}],"department":[{"_id":"MiLe"}],"language":[{"iso":"eng"}],"oa_version":"Published Version","ddc":["530"],"OA_place":"publisher","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)"},"status":"public","title":"Electron–electrolyte coupling in AC transport through nanofluidic channels","volume":164,"date_updated":"2026-05-18T07:34:57Z","article_type":"original","fulldoi":"https://doi.org/10.1063/5.0313352","has_accepted_license":"1","quality_controlled":"1","file_date_updated":"2026-05-18T07:31:23Z","article_processing_charge":"Yes (in subscription journal)","_id":"21840","issue":"13","intvolume":" 164","article_number":"134704","OA_type":"hybrid","publication_identifier":{"issn":["0021-9606"],"eissn":["1089-7690"]},"publication_status":"published","doi":"10.1063/5.0313352","PlanS_conform":"1","type":"journal_article"},{"acknowledgement":"We thank a variety of further colleagues for the many inspiring discussions on the nature of heredity, especially the workshops in Berlin.

Yet this paradigm is increasingly recognized as inadequate for explaining continuous phenotypic variation and the complex genetic architectures of the genotype–phenotype map. Modern genetics emerged from the early 20th-century synthesis of Mendelian and biometric schools of heredity, with R.A. Fisher demonstrating early on how multiple discrete loci could collectively produce continuous variation. Despite this fundamental insight, Mendelism—with its focus on single genes and standardized genetic backgrounds—became the dominant framework, shaping current genetics research and molecular biology as well as science education. The advent of large-scale genomic data has revealed yet again the limitations of this reductionist approach. Evidence from quantitative genetics now shows that most phenotypes arise from complex networks of many interdependent genes and their dynamic responses to environmental perturbations. Here we trace the historical roots of how Mendelian classical genetics departed from the biometric school to create the current predominant paradigm in genetics, despite fundamentally unresolved issues. Moving on from this one-sided paradigm will require systematic development of integrative, evolutionarily grounded experimental approaches that better capture the multigenic and context-dependent nature of inheritance. Achieving such an extended perspective will require methodological innovation, including advances in large-scale (e.g. automated) phenotyping. Dedicated research programs will be necessary to advance a new era of genetic research into the complex mechanisms underlying phenotypic variation.","lang":"eng"}],"language":[{"iso":"eng"}],"department":[{"_id":"NiBa"}],"oa":1,"day":"01","date_created":"2026-05-07T08:53:40Z","author":[{"full_name":"Tautz, Diethard","first_name":"Diethard","last_name":"Tautz"},{"full_name":"Pallares, Luisa F","first_name":"Luisa F","last_name":"Pallares"},{"first_name":"Leif","last_name":"Andersson","full_name":"Andersson, Leif"},{"first_name":"Neda","last_name":"Barghi","full_name":"Barghi, Neda"},{"last_name":"Barton","first_name":"Nicholas H","full_name":"Barton, Nicholas H","orcid":"0000-0002-8548-5240","id":"4880FE40-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Bay","first_name":"Rachael","full_name":"Bay, Rachael"},{"first_name":"Yingguang Frank","last_name":"Chan","full_name":"Chan, Yingguang Frank"},{"first_name":"Angela","last_name":"Hancock","full_name":"Hancock, Angela"},{"last_name":"Kaiser","first_name":"Tobias S","full_name":"Kaiser, Tobias S"},{"full_name":"Koenig, Daniel","last_name":"Koenig","first_name":"Daniel"},{"full_name":"Kontarakis, Zacharias","last_name":"Kontarakis","first_name":"Zacharias"},{"first_name":"Miriam","last_name":"Liedvogel","full_name":"Liedvogel, Miriam"},{"full_name":"de Meaux, Juliette","last_name":"de Meaux","first_name":"Juliette"},{"full_name":"Nordborg, Magnus","first_name":"Magnus","last_name":"Nordborg"},{"last_name":"Palmer","first_name":"Abraham A","full_name":"Palmer, Abraham A"},{"full_name":"Purugganan, Michael","first_name":"Michael","last_name":"Purugganan"},{"last_name":"Schlötterer","first_name":"Christian","full_name":"Schlötterer, Christian"},{"last_name":"Schmid","first_name":"Karl","full_name":"Schmid, Karl"},{"last_name":"Stainier","first_name":"Didier Y R","full_name":"Stainier, Didier Y R"},{"full_name":"Weigel, Detlef","first_name":"Detlef","last_name":"Weigel"},{"full_name":"Wolf, Jochen B W","first_name":"Jochen B W","last_name":"Wolf"},{"last_name":"Ebert","first_name":"Dieter","full_name":"Ebert, Dieter"},{"full_name":"Gibson, Greg","last_name":"Gibson","first_name":"Greg"}],"publisher":"Oxford University Press","citation":{"ieee":"D.

Their high abundance at redshifts of z ∼ 6–8 and decline at lower redshifts suggest a transient origin. We propose that the spectral shape of LRDs originates from compact binary black hole systems, in which each black hole is surrounded by a mini-disk and embedded within a larger circumbinary disk. With a binary separation of ≲103 Schwarzschild radii, the Wien tail of a T ≃ 5000 K blackbody spectrum at the inner edge of the circumbinary disk produces the red optical emission, while the mini-disks power the UV continuum. Binary torques carve out a gap between the circumbinary disk and the mini-disks, setting the turnover wavelength of the V-shaped spectrum around the Balmer limit. This scenario naturally reproduces LRD spectra requiring only modest dust attenuation (AV ≲ 1 mag), resolving overestimated luminosities for LRDs in previous studies and alleviating a tension with the so-called Sołtan argument. This model predicts distinct spectral evolution as the binary orbit decays through binary disk interactions and gravitational-wave (GW) emission, linking early-stage “proto-LRD” binaries to the broader AGN population and late-stage “LRD descendants” to coalescing binaries detectable in GW experiments."}],"oa":1,"date_created":"2026-05-10T22:02:14Z","day":"01","author":[{"full_name":"Inayoshi, Kohei","last_name":"Inayoshi","first_name":"Kohei"},{"first_name":"Jinyi","last_name":"Shangguan","full_name":"Shangguan, Jinyi"},{"last_name":"Chen","first_name":"Xian","full_name":"Chen, Xian"},{"last_name":"Ho","first_name":"Luis C.","full_name":"Ho, Luis C."},{"full_name":"Haiman, Zoltán","orcid":"0000-0003-3633-5403","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman","first_name":"Zoltán"}],"publisher":"IOP Publishing","citation":{"mla":"Inayoshi, Kohei, et al. “The Emergence of Little Red Dots from Binary Massive Black Holes.” The Astrophysical Journal, vol. 1002, no. 1, 25, IOP Publishing, 2026, doi:10.3847/1538-4357/ae548d.","ista":"Inayoshi K, Shangguan J, Chen X, Ho LC, Haiman Z. 2026.

One potential pairing mechanism, invoked in the related re-entrant superconductors UCoGe and URhGe, involves transverse fluctuations of a ferromagnetic order parameter. However, the requisite ferromagnetic order—present in both UCoGe and URhGe—is absent in UTe2, and neutron scattering shows instead that the magnetic susceptibility is peaked at an antiferromagnetic wavevector. Here, we measure the magnetotropic susceptibility of UTe2 across two field-angle planes. This quantity is sensitive to the magnetic susceptibility in a direction transverse to the applied magnetic field—a quantity that is not accessed in conventional magnetization measurements. We observe a very large decrease in the magnetotropic susceptibility over a broad range of field orientations, indicating a large increase in the transverse magnetic susceptibility. Because our technique probes the magnetic susceptibility in the long wavelength (q = 0) limit, this suggests that the strong transverse susceptibility arises from ferromagnetic spin fluctuations. These ferromagnetic fluctuations are likely important for understanding the pairing mechanism in UTe2, as all three superconducting phases of UTe2 surround this region of enhanced susceptibility in the field-angle phase diagram."}],"language":[{"iso":"eng"}],"department":[{"_id":"KiMo"},{"_id":"GradSch"}],"oa":1,"day":"29","date_created":"2026-05-10T22:02:15Z","author":[{"full_name":"Zambra, Valeska","orcid":"0000-0002-8806-5719","id":"467ed36b-dc96-11ea-b7c8-b043a380b282","last_name":"Zambra","first_name":"Valeska"},{"id":"1a362536-4d02-11f1-8543-8351136efc50","full_name":"Nathwani, Amit","last_name":"Nathwani","first_name":"Amit"},{"last_name":"Nauman","first_name":"Muhammad","full_name":"Nauman, Muhammad","orcid":"0000-0002-2111-4846","id":"32c21954-2022-11eb-9d5f-af9f93c24e71"},{"full_name":"Lewin, Sylvia K.","last_name":"Lewin","first_name":"Sylvia K."},{"full_name":"Frank, Corey E.","first_name":"Corey E.","last_name":"Frank"},{"last_name":"Butch","first_name":"Nicholas P.","full_name":"Butch, Nicholas P."},{"last_name":"Shekhter","first_name":"Arkady","full_name":"Shekhter, Arkady"},{"full_name":"Ramshaw, B.

This fraction is even higher when smaller spatial scales are probed at high signal-to-noise ratio: the two most strongly lensed LRDs, A383-LRD1 and the newly discovered A68-LRD1, both have UV-bright companions at separations of only d ∼ 0.3 kpc, below the resolution limit of most unlensed JWST samples. We explore whether these ubiquitous red/blue configurations may be physically linked to the formation of LRDs, in analogy with the “synchronized pair” scenario originally proposed for direct-collapse black hole formation. In this picture, UV radiation from the companions, with typically modest stellar masses (M∗ ∼ 108−109 M⊙), suppresses molecular hydrogen cooling in nearby gas, allowing nearly isothermal collapse and the formation of extremely compact objects, such as massive black holes, supermassive stars, or quasi-stars. Using component-resolved photometry and spectral energy distribution modeling, we infer Lyman–Werner radiation fields of J21,LW ∼ 102.5–105 at the locations of the red components, comparable to those required in direct-collapse models, suggesting that the necessary photodissociation conditions are realized in many LRD systems. This framework provides a simple and self-consistent explanation for the extreme compactness and distinctive spectral properties of LRDs and links long-standing theoretical models for early compact object formation directly to a population now observed with JWST in the early Universe."}],"language":[{"iso":"eng"}],"department":[{"_id":"ZoHa"},{"_id":"JoMa"}],"oa":1,"ddc":["520"],"OA_place":"publisher","oa_version":"Published Version","volume":1002,"date_updated":"2026-05-11T06:48:33Z","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)"},"title":"Connecting the dots: UV-bright companions of Little Red Dots as Lyman–Werner sources enabling direct-collapse Black Hole formation","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","acknowledgement":"We thank Earl Bellinger, Fabio Pacucci, Andrea Ferrara, and Dale Kocevski for useful discussions.

However, extracting physical insights from experimental data is often hindered by measurement noise, limited observables, and incomplete knowledge of the underlying microscopic model. Here, we develop a machine learning approach based on a variational autoencoder (VAE) to analyze interference measurements of tunnel-coupled one-dimensional Bose gases, which realize the sine-Gordon quantum field theory. Trained in an unsupervised manner, the VAE learns a minimal latent representation that strongly correlates with the equilibrium control parameter of the system. Applied to nonequilibrium protocols, the latent space uncovers signatures of frozen-in solitons following rapid cooling, and reveals anomalous postquench dynamics not captured by conventional correlation-based methods. These results demonstrate that generative models can extract physically interpretable variables directly from noisy and sparse experimental data, providing complementary probes of equilibrium and nonequilibrium physics in quantum simulators. More broadly, our work highlights how machine learning can supplement established field-theoretical techniques, paving the way for scalable, data-driven discovery in quantum many-body systems.","lang":"eng"}],"department":[{"_id":"EdHa"}],"language":[{"iso":"eng"}],"author":[{"full_name":"Moller, Frederik Skovbo","id":"43cbcc83-0564-11f0-a935-e37325525859","first_name":"Frederik Skovbo","last_name":"Moller"},{"first_name":"Gabriel","last_name":"Fernández-Fernández","full_name":"Fernández-Fernández, Gabriel"},{"full_name":"Schweigler, Thomas","first_name":"Thomas","last_name":"Schweigler"},{"last_name":"De Schoulepnikoff","first_name":"Paulin","full_name":"De Schoulepnikoff, Paulin"},{"full_name":"Schmiedmayer, Jörg","first_name":"Jörg","last_name":"Schmiedmayer"},{"last_name":"Muñoz-Gil","first_name":"Gorka","full_name":"Muñoz-Gil, Gorka"}],"publisher":"American Physical Society","citation":{"mla":"Moller, Frederik Skovbo, et al. “Learning Minimal Representations of Many-Body Physics from Snapshots of a Quantum Simulator.” Physical Review Research, vol. 8, no. 2, 023094, American Physical Society, 2026, doi:10.1103/r7pj-gl7r.","ista":"Moller FS, Fernández-Fernández G, Schweigler T, De Schoulepnikoff P, Schmiedmayer J, Muñoz-Gil G. 2026.

In this study, we report on a targeted delivery system for mRNA to a specific subset of skin-resident antigen-presenting cells: Langerhans cells. By functionalizing lipid nanoparticles with a langerin-specific glycomimetic ligand, we achieve selective mRNA delivery to both murine and human primary Langerhans cells with minimal off-target uptake, at the same time resulting in significantly increased mRNA translation. This targeted mRNA delivery not only enhances antigen presentation and T-cell responses but also enables dose-sparing and superior antitumor immunity compared with conventional immunization in a B16-OVA tumor model.

The α-ketoglutarate dehydrogenase complex (αKGDHC), an enzyme of the tricarboxylic acid cycle, represents a branching point controlling glutamate formation and its consumption as a fuel. Hence, modulation of the activity of αKGDHC might alter the amount of glutamate available for excitotoxic effects. To address this hypothesis, hippocampal neurons in primary co-culture with glial cells were exposed to zero-Mg2 buffer to elicit excitotoxicity through N-methyl-D-aspartic acid (NMDA) receptor disinhibition. Pretreatment of the cultures with succinyl phosphonate, to inhibit αKGDHC, enhanced excitotoxity, whereas promotion of αKGDHC activity by pretreatment with thiamine caused an opposite action. Moreover, NMDA receptor currents – but not those mediated by α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors – were potentiated in neurons with impaired αKGDHC activity and diminished in neurons with boosted αKGDHC activity. The sensitization of NMDA receptors involved mGluR1 activation and was accompanied by enhanced neuronal discharge activity, elevated basal cytosolic Ca2+ levels, and augmented Ca2+ responses evoked by glutamate application. These results suggest that mGluR1-mediated potentiation of NMDA receptors contributes to a mechanism by which inhibition of αKGDHC might exacerbate glutamate excitotoxicity."}],"language":[{"iso":"eng"}],"department":[{"_id":"Bio"}],"oa":1,"day":"27","date_created":"2026-05-11T10:52:27Z","citation":{"apa":"Goeschl, V., Hotka, M., Hochreiter, B., Hilber, K., Boehm, S., Kozlov, A.

In this paper, we instead use recombination lines to infer the intrinsic properties of the central engine. Our analysis first reveals a tension between the ionizing properties implied from Hα and He ii λ4686. The high Hα EWs require copious H-ionizing photons, more than the bluest active galactic nucleus (AGN) ionizing spectra can provide. In contrast, He ii emission is marginally detected, and its low EW is, at most, consistent with the softest AGN spectra. The low He ii/Hβ (∼10−2, <20× local AGN median) further points to an unusually soft ionizing spectrum. We extend our analysis to dense gas envelopes (quasi-star/black-hole star) and find that hydrogen recombination lines become optically thick and lose diagnostic power, but He ii remains optically thin and a robust tracer. Photoionization modeling with Cloudy rules out standard AGN accretion disk spectra. Alternative explanations include exotic AGN with red rest-optical emission, high average optical depth (>10) from gas/dust, and soft ionizing spectra with abundant H-ionizing photons, consistent with, e.g., a cold accretion disk or a composite of AGN and stars. The latter is an intriguing scenario since high hydrogen densities are highly conducive for star formation, and nuclear star clusters are found in the vicinity of local massive black holes. While previous studies have mostly focused on features dominated by the absorbing hydrogen cloud, the He ii-based diagnostic proposed here represents a crucial step toward understanding the central engine of LRDs.","lang":"eng"}],"oa_version":"Published Version","OA_place":"publisher","ddc":["520"],"status":"public","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)"},"title":"The missing hard photons of Little Red Dots: Their incident ionizing spectra resemble massive stars","date_updated":"2026-05-18T08:18:39Z","volume":1003,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"05","arxiv":1,"date_published":"2026-05-01T00:00:00Z","acknowledgement":"B.W. thanks Michael Eracleous for valuable discussions.

In its original form, it is highly\r\nsingular and fails to be renormalizable, even by approaches such as regularity structures and paracontrolled distributions, hindering mathematical approaches to its rigorous justification. It has been understood recently that it is\r\nnatural to introduce a suitable regularization, for example, by applying a formal spatial discretization or by truncating high-frequency noise: This yields\r\nwell-posed equations that should still precisely approximate the law of the\r\nparticle density fluctuations.\r\nIn the present work, we prove that a regularization in the form of a formal\r\ndiscretization of the Dean–Kawasaki equation indeed accurately describes\r\ndensity fluctuations in systems of weakly interacting diffusing particles: We\r\nshow that, in suitable weak metrics, the law of fluctuations as predicted by\r\nthe discretized Dean–Kawasaki SPDE approximates the law of fluctuations\r\nof the original particle system, up to an error that is of arbitrarily high order in\r\nthe inverse particle number and a discretization error. In particular, the Dean–\r\nKawasaki equation provides a means for efficient and accurate simulations of\r\ndensity fluctuations in weakly interacting particle systems."}],"language":[{"iso":"eng"}],"department":[{"_id":"JuFi"}],"oa":1,"day":"01","date_created":"2026-05-20T08:25:25Z","publisher":"Institute of Mathematical Statistics","author":[{"full_name":"Cornalba, Federico","last_name":"Cornalba","first_name":"Federico"},{"full_name":"Fischer, Julian L","id":"2C12A0B0-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0479-558X","last_name":"Fischer","first_name":"Julian L"},{"full_name":"Ingmanns, Jonas","id":"71523d30-15b2-11ec-abd3-f80aa909d6b0","orcid":"0009-0008-1310-7946","last_name":"Ingmanns","first_name":"Jonas"},{"last_name":"Raithel","first_name":"Claudia","full_name":"Raithel, Claudia"}],"citation":{"mla":"Cornalba, Federico, et al. “Density Fluctuations in Weakly Interacting Particle Systems via the Dean–Kawasaki Equation.” The Annals of Probability, vol. 54, no. 1, Institute of Mathematical Statistics, 2026, pp. 155–215, doi:10.1214/25-aop1763.","ista":"Cornalba F, Fischer JL, Ingmanns J, Raithel C. 2026.
