The low-temperature quasi-universal behavior of amorphous solids has been attributed to
the existence of spatially localized tunneling defects found in the low-energy regions of the
potential energy landscape. Computational models of glasses can be studied to elucidate
the microscopic nature of these defects. Recent simulation work has demonstrated the
means of generating stable glassy configurations for models that mimic metallic glasses
using the swap Monte Carlo algorithm. Building on these studies, we present an extensive …
