Estimating the density scaling exponent of viscous liquids from specific heat and bulk modulus data
Ulf R. Pedersen, Tina Hecksher, Bo Jakobsen +4
It was recently shown by computer simulations that a large class of liquids exhibits strong correlations in their thermal fluctuations of virial and potential energy [Pedersen et a…
Pressure-energy correlations in liquids. II. Analysis and consequences
Nicholas P. Bailey, Ulf R. Pedersen, Nicoletta Gnan +2
We present an analysis and discuss consequences of the strong correlations of the configurational parts of pressure and energy in their equilibrium fluctuations at fixed volume rep…
Pressure-energy correlations in liquids. I. Results from computer simulations
Nicholas P. Bailey, Ulf R. Pedersen, Nicoletta Gnan +2
We show that a number of model liquids at fixed volume exhibit strong correlations between equilibrium fluctuations of the configurational parts of (instantaneous) pressure and ene…
Glass-forming liquids: One or more "order" parameters?
Nicholas P. Bailey, Tage Christensen, Bo Jakobsen +5
We first summarize the classical arguments that the vast majority of glass-forming liquids require more than one "order" parameter for their description. Critiques against this con…
Feasibility of single-order parameter description of equilibrium viscous liquid dynamics
Ulf R. Pedersen, Tage Christensen, Thomas B. Schrøder +1
Molecular dynamics results for the dynamic Prigogine-Defay ratio are presented for two glass-forming liquids, thus evaluating the experimentally relevant quantity for testing wheth…
Single-order-parameter description of glass-forming liquids: A one-frequency test
Niels L. Ellegaard, Tage Christensen, Peder Voetmann Christiansen +4
Thermo-viscoelastic linear-response functions are calculated from the master equation describing viscous liquid inherent dynamics. From the imaginary parts of the frequency-depende…
