Ductile-to-brittle transition and yielding in soft amorphous materials: perspectives and open questions
Thibaut Divoux, Elisabeth Agoritsas, Stefano Aime +37
Soft amorphous materials are viscoelastic solids ubiquitously found around us, from clays and cementitious pastes to emulsions and physical gels encountered in food or biomedical e…
Scale-Equivariant Imaging: Self-Supervised Learning for Image Super-Resolution and Deblurring
Jérémy Scanvic, Mike Davies, Patrice Abry +1
Self-supervised methods have recently proved to be nearly as effective as supervised ones in various imaging inverse problems, paving the way for learning-based approaches in scien…
Surface quantum critical phenomena in disordered Dirac semimetals
Eric Brillaux, Andrei A. Fedorenko, Ilya A. Gruzberg
We study a non-Anderson disorder driven quantum phase transition in a semi-infinite Dirac semimetal with a flat boundary. The conformally invariant boundary conditions, which inclu…
Entanglement entropy of two disjoint intervals and spin structures in interacting chains in and out of equilibrium
Vanja Marić, Saverio Bocini, Maurizio Fagotti
We take the paradigm of interacting spin chains, the Heisenberg spin- XXZ model, as a reference system and consider interacting models that are related to it by Jordan…
Equivariant plug-and-play image reconstruction
Matthieu Terris, Thomas Moreau, Nelly Pustelnik +1
Plug-and-play algorithms constitute a popular framework for solving inverse imaging problems that rely on the implicit definition of an image prior via a denoiser. These algorithms…
Virtual potential created by a feedback loop: taming the feedback demon to explore stochastic thermodynamics of underdamped systems
Salambô Dago, Nicolas Barros, Jorge Pereda +2
Virtual potentials are an elegant, precise and flexible tool to manipulate small systems and explore fundamental questions in stochastic thermodynamics. In particular double-well p…
