Ductile-to-brittle transition and yielding in soft amorphous materials: perspectives and open questions

T Divoux, E Agoritsas, S Aime, C Barentin, JL Barrat… - Soft Matter, 2024 - pubs.rsc.org
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 …

Irreversible Monte Carlo algorithms for hard disk glasses: From event-chain to collective swaps

F Ghimenti, L Berthier, F van Wijland - Physical Review Letters, 2024 - APS
Equilibrium sampling of the configuration space in disordered systems requires algorithms
that bypass the glassy slowing down of the physical dynamics. Irreversible Monte Carlo …

Irreversible Boltzmann samplers in dense liquids: Weak-coupling approximation and mode-coupling theory

F Ghimenti, L Berthier, G Szamel, F van Wijland - Physical Review E, 2024 - APS
Exerting a nonequilibrium drive on an otherwise equilibrium Langevin process brings the
dynamics out of equilibrium but can also speed up the approach to the Boltzmann steady …

Normalizing flows as an enhanced sampling method for atomistic supercooled liquids

G Jung, G Biroli, L Berthier - Machine Learning: Science and …, 2024 - iopscience.iop.org
Normalizing flows can transform a simple prior probability distribution into a more complex
target distribution. Here, we evaluate the ability and efficiency of generative machine …

Enhanced diffusion of tracer particles in nonreciprocal mixtures

A Benois, M Jardat, V Dahirel, V Démery… - Physical Review E, 2023 - APS
We study the diffusivity of a tagged particle in a binary mixture of Brownian particles with
nonreciprocal interactions. Numerical simulations reveal that, for a broad class of interaction …

Dance of odd-diffusive particles: A Fourier approach

A Langer, A Sharma, R Metzler, E Kalz - Physical Review Research, 2024 - APS
Odd-diffusive systems are characterized by transverse responses and exhibit
unconventional behaviors in interacting systems. To address the dynamical interparticle …

Role of interactions in nonequilibrium transformations

M Rose, SK Manikandan - Physical Review E, 2024 - APS
For arbitrary nonequilibrium transformations in complex systems, we show that the distance
between the current state and a target state can be decomposed into two terms: one …

Transverse forces and glassy liquids in infinite dimensions

F Ghimenti, L Berthier, G Szamel, F van Wijland - Physical Review E, 2024 - APS
We explore the dynamics of a simple liquid whose particles, in addition to standard potential-
based interactions, are also subjected to transverse forces preserving the Boltzmann …

Non-reciprocal spin-glass transition and aging

GG Lorenzana, A Altieri, G Biroli, M Fruchart… - arXiv preprint arXiv …, 2024 - arxiv.org
Disordered systems generically exhibit aging and a glass transition. Previous studies have
long suggested that non-reciprocity tends to destroy glassiness. Here, we show that this is …

Solving the Kinetic Ising Model with Non-Reciprocity

G Weiderpass, M Sharma, S Sethi - arXiv preprint arXiv:2410.23615, 2024 - arxiv.org
Non-reciprocal interactions are a generic feature of non-equilibrium systems. We define a
non-reciprocal generalization of the kinetic Ising model in one spatial dimension. We solve …
