We compute the shear modulus of structural glasses from a first-principles approach based on the cloned liquid theory. We find that the intrastate shear modulus, which corresponds to the plateau modulus measured in linear viscoelastic measurements, strongly depends on temperature and vanishes continuously when the temperature is increased beyond the glass temperature.

Abstract
We compute the shear modulus of structural glasses from a first-principles approach based on the cloned liquid theory. We find that the intrastate shear modulus, which corresponds to the plateau modulus measured in linear viscoelastic measurements, strongly depends on temperature and vanishes continuously when the temperature is increased beyond the glass temperature.
