Traditionally, the formation of amorphous shear bands in crystalline materials has been
undesirable, because shear bands can nucleate voids and act as precursors to fracture …

Plastic deformation and relaxation dynamics are two major topics in glass physics.
Secondary (β) relaxation has been assumed to be a relevant plastic mechanism in …

The state-of-the-art experimental and atomistic simulation techniques were utilized to study
the structure of the liquid and amorphous Ni 62 Nb 38 alloy. First, the ab initio molecular …

We investigate the fast β-and Johari–Goldstein (JG) β-relaxation processes, along with the
elastic scattering response of glass-forming (GF) liquids and the boson peak, in a simulated …

When metallic glasses (MGs) are subjected to mechanical loads, the plastic response of
atoms is non-uniform. However, the extent and manner in which atomic environment …

Today's technologies are primarily based on crystalline materials (metals, semiconductors,
etc.), as their properties can be controlled by varying their chemical and/or defect …

Interatomic potentials based on neural-network machine learning (ML) approach to address
the long-standing challenge of accuracy versus efficiency in molecular-dynamics …

Local atomic environment (LAE) representations have enabled a deeper understanding of
complex alloy configurations, by enabling machine learning and data science approaches to …

The Johari-Goldstein secondary (β) relaxations are intrinsic features of supercooled liquids
and glasses, and they play a crucial role in several properties of glassy materials. However …

Relaxation processes significantly influence the properties of glass materials. However,
