Score-based denoising for atomic structure identification
Tim Hsu, Babak Sadigh, Nicolas Bertin +4
We propose an effective method for removing thermal vibrations that complicate the task of analyzing complex dynamics in atomistic simulation of condensed matter. Our method iterat…
Enhanced mobility of dislocation network nodes and its effect on dislocation multiplication and strain hardening
Nicolas Bertin, Wei Cai, Sylvie Aubry +2
Understanding plastic deformation of crystals in terms of the fundamental physics of dislocations has remained a grand challenge in materials science for decades. To overcome this,…
Accelerating discrete dislocation dynamics simulations with graph neural networks
Nicolas Bertin, Fei Zhou
Discrete dislocation dynamics (DDD) is a widely employed computational method to study plasticity at the mesoscale that connects the motion of dislocation lines to the macroscopic…
Numerical simulation of universal morphogenesis of fluid interface deformations driven by radiation pressure
Hugo Chesneau, Hamza Chraibi, Nicolas Bertin +4
We report on ab initio simulation of fluid interface deformations induced either by acoustic or optical radiation pressure. This is done by solving simultaneously the scalar wave p…
Energy storage under high-rate compression of single crystal tantalum
Jared C. Stimac, Nicolas Bertin, Jeremy K. Mason +1
When a material is plastically deformed the majority of mechanical work is dissipated as heat, and the fraction of plastic work converted into heat is known as the Taylor-Quinney c…
