Thermal softening of the yield stress in glasses with different stability
Tianze Wan, Ludovic Berthier
The yielding of amorphous solids has been extensively studied in the athermal limit, but the influence of thermal fluctuations is much less understood, in particular for glasses of…
How to quantify long-time rotational motion in molecular systems
Romain Simon, Hadrien Bobas, François Villemot +2
We show that all existing methods quantifying rotational motion in molecular fluids eventually have severe limitations in systems undergoing complex rotational motion characterized…
Boltzmann generators for amorphous particle systems
Louis Grenioux, Leonardo Galliano, Ludovic Berthier +2
Sampling configurations in thermodynamic equilibrium is a long-standing challenge in statistical physics. Boltzmann generators address this problem by employing generative models t…
Numerical investigation of the equilibrium Kauzmann transition in a two-dimensional atomistic glass
Gerhard Jung, Misaki Ozawa, Giulio Biroli +1
Dense liquids gradually transform into non-equilibrium amorphous solids as they pass through the experimental glass transition. Experimentally, ergodicity is lost because measureme…
Molecular motion at the experimental glass transition
Romain Simon, Jean-Louis Barrat, Ludovic Berthier
We propose a novel computational strategy to study the glass transition of molecular fluids. Our approach combines the construction of simple yet realistic models with the developm…
Normalizing flows as an enhanced sampling method for atomistic supercooled liquids
Gerhard Jung, Giulio Biroli, Ludovic Berthier
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…
Yielding and plasticity in amorphous solids
Ludovic Berthier, Giulio Biroli, M. Lisa Manning +1
The physics of disordered media, from metallic glasses to colloidal suspensions, granular matter and biological tissues, offers difficult challenges because it often occurs far fro…
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…
Roadmap on machine learning glassy dynamics
Gerhard Jung, Rinske M. Alkemade, Victor Bapst +10
Unraveling the connections between microscopic structure, emergent physical properties, and slow dynamics has long been a challenge when studying the glass transition. The absence…
Dynamic heterogeneity at the experimental glass transition predicted by transferable machine learning
Gerhard Jung, Giulio Biroli, Ludovic Berthier
We develop a transferable machine learning model which predicts structural relaxation from amorphous supercooled liquid structures. The trained networks are able to predict dynamic…
Predicting plasticity in disordered solids from structural indicators
D. Richard, M. Ozawa, S. Patinet +16
Amorphous solids lack long-range order. Therefore identifying structural defects -- akin to dislocations in crystalline solids -- that carry plastic flow in these systems remains a…
