Absence of a structural glass phase in a monoatomic model liquid predicted to undergo an ideal glass transition

TL;DR

This study numerically investigates a monodisperse particle model predicted to have a liquid-glass transition but finds no evidence of a glassy phase, instead observing trivial collapse or crystalline structures.

Contribution

It demonstrates that the specific monodisperse model does not exhibit an ideal glass transition, challenging previous predictions.

Findings

No glassy phase observed at low temperatures.

System either collapses trivially or forms crystalline structures.

Model does not support the predicted static liquid-glass transition.

Abstract

We study numerically a monodisperse model of interacting classical particles predicted to exhibit a static liquid-glass transition. Using a dynamical Monte Carlo method we show that the model does not freeze into a glassy phase at low temperatures. Instead, depending on the choice of the hard-core radius for the particles the system either collapses trivially or a polycrystalline hexagonal structure emerges.
