Understanding the origin of the dramatic temperature and density dependence of the relaxation time of glass-forming liquids is a fundamental challenge in glass science. The recently established density-scaling relation quantifies the relative importance of temperature and density for the relaxation time in terms of amaterial-dependent exponent. We showthat this exponent for approximate single-parameter liquids can be calculated from thermoviscoelastic linear-response data at a single state point, for instance an ambient-pressure ...
