Transmutation-accelerated sampling method for multicomponent ZrCu(Al) metallic glasses

We investigate multicomponent metallic glass systems using a hybrid molecular dynamics (MD) and variance-constrained semi-grand-canonical approach. This method enables us to generate samples with properties consistent with experimental observations, at deeply supercooled states that are typically inaccessible with conventional MD simulations. Using a realistic interatomic potential, we investigate the dynamics, kinetic stability, and rheology of a ZrCu(Al) metallic glass, together with the widely studied ZrCu system, in the low-temperature glassy regime. Our results demonstrate how the hybrid method enhances relaxation and provides a generic framework for modeling realistic complex metallic glasses.
