TLDR
Berthier et al. as mentioned in this paper developed Monte Carlo methods for two-dimensional glass-forming liquids that allow us to access equilibrium states at sufficiently low temperatures to directly probe the glass transition in a regime inaccessible to experiments.Abstract:
Liquids cooled towards the glass transition temperature transform into amorphous solids that have a wide range of applications. While the nature of this transformation is understood rigorously in the mean-field limit of infinite spatial dimensions, the problem remains wide open in physical dimensions. Nontrivial finite-dimensional fluctuations are hard to control analytically, and experiments fail to provide conclusive evidence regarding the nature of the glass transition. Here, we develop Monte Carlo methods for two-dimensional glass-forming liquids that allow us to access equilibrium states at sufficiently low temperatures to directly probe the glass transition in a regime inaccessible to experiments. We find that the liquid state terminates at a thermodynamic glass transition which occurs at zero temperature and is associated with an entropy crisis and a diverging static correlation length. Our results thus demonstrate that a thermodynamic glass transition can occur in finite dimensional glass-formers. Identifying the nature of the glass transition is challenging because relevant experiments or analytical descriptions are hard to achieve. Here, Berthier et al. develop a Monte Carlo numerical tool to investigate two-dimensional glasses and find a zero-temperature thermodynamic glass transition.read more

Models and algorithms for the next generation of glass transition studies
TL;DR: In this paper, a comprehensive analysis of eleven glass-forming models is presented to demonstrate that both structural ordering and the dramatic increase of relaxation times at low temperatures can be efficiently tackled using carefully designed models of size polydisperse supercooled liquids together with an efficient Monte Carlo algorithm where translational particle displacements are complemented by swaps of particle pairs.
