Revisiting quantum effects on dislocation glide in bcc metals from DFT calculations and machine-learning potentials
Arnaud Allera, Lisa Ventelon, Mihai-Cosmin Marinica +2
Quantum zero-point effects have been long proposed to explain a well-known discrepancy between the low-temperature flow stresses of body-centered cubic metals and corresponding ato…

Unveiling and quantifying the topology-dependent pre-melting of nanoparticles
Marthe Bideault, Arnaud Allera, Ryoji Asahi +2
The melting of metallic nanoparticles is governed by surface premelting, a phenomenon traditionally modeled as the isotropic growth of a uniform liquid shell. Challenging this clas…
