The glass transition and liquid-gas spinodal boundaries of metastable liquids

Abstract

A liquid can exist under conditions of thermodynamic stability or metastability within boundaries defined by the liquid-gas spinodal and the glass transition line. The relationship between these boundaries has been investigated previously using computer simulations, the energy landscape formalism, and simplified model calculations. We calculate these stability boundaries semi-analytically for a model glass forming liquid, employing accurate liquid state theory and a first-principles approach to the glass transition. These boundaries intersect at a finite temperature, consistent with previous simulation-based studies.

“…We further note that such an arrested phase separation scheme also applies to the case of longer-range attractive potential. Studies of a Lennard-Jones potential [162,163] and of a larger (15%) SW model [164], for which the Noro-Frenkel mapping does not apply, have also reported that the glass line meets the two-phase region on the right-hand side of the critical point.…”

Maximum valency lattice gas models

“…As a result, the establishment of conditions such that a connected percolating structure able to sustain stress survives for times longer than the observation time is often preempted by phase separation. For spherical attractive interaction potentials, it has been found that phase separation is always dominant at low densities and arrested states at low packing fractions φ can be reached only in non-homogeneous state, whose morphology is determined by the phase separation process [13,14,15,16,17,18,19].…”
