Non-linear jog-dragging effect on the mobility law of edge dislocations in face-centered cubic nickel
Wu-Rong Jian, Yifan Wang, Wei Cai
Dislocation jogs have strong effects on dislocation motion that governs the strain-hardening behavior of crystalline solids, but how to properly account for their effect in mesosca…

Room-temperature vacancy emission from the jog on edge dislocation in FCC nickel under glide force
Yifan Wang, Wu-Rong Jian, Wei Cai
Jogs, atomic-scale steps on dislocations, play an important role in crystal plasticity, yet they are often ignored in discrete dislocation dynamics (DDD) simulations due to their s…

Generalizability of Graph Neural Network Force Fields for Predicting Solid-State Properties
Shaswat Mohanty, Yifan Wang, Wei Cai
Machine-learned force fields (MLFFs) promise to offer a computationally efficient alternative to ab initio simulations for complex molecular systems. However, ensuring their genera…
