• Thermodynamics of self-gravitating fermions as a robust theory for dark matter halos: Stability analysis applied to the Milky Way · 2026

  Résumé de la publication : We present a framework for dark matter (DM) halo formation based on a kinetic theory of self-gravitating fermions together with a solid connection to thermodynamics. Based on maximum entropy arguments, this approach predicts a most likely phase-space distribution which takes into account…

• Cheaper access to universal fluctuations in integrable spin chains from boundary effects · 2026

  Résumé de la publication : Observing super-diffusive fluctuations from Kardar-Parisi-Zhang (KPZ) universality in isotropic integrable spin chains is usually challenging as it requires a fairly large number of spins in interaction. We demonstrate in this paper, in the context of classical spins, that accounting for boundary effects…

• Detecting the largest correlations for many-body systems using the correlation density matrix: A quantum Monte Carlo approach · 2026

  Résumé de la publication : We present a quantum Monte Carlo-based approach to detect and compute the most dominant correlations for many-body systems without prior knowledge. It is based on the measurement and analysis of the correlation density matrix between two (small) subsystems embedded in the full…

• Enhanced Diffusion of Single, Lipid-Tethered Enzymes · 2026

  Résumé de la publication : Recent experimental evidence has shown that enzymes that catalyze exergonic reactions are able to diffuse faster during catalysis, a process called “enhanced diffusion”. If true, enzyme propulsion could enable the engineering of designed active materials at the nanoscale. However, further experimental validation…

• Opinion Formation at Ising Social Networks · 2026

  Résumé de la publication : We study the process of opinion formation in an Ising social network of scientific collaborations. The network is undirected. An Ising spin is associated with each network node being oriented up (red) or down (blue). Certain nodes carry fixed, opposite opinions whose…
