Unified Theory of Activated Relaxation in Liquids over 14 Decades in Time
Unified Theory of Activated Relaxation in Liquids over 14 Decades in Time
We formulate a predictive theory at the level of forces of activated relaxation in hard sphere fluids and thermal liquids that covers in a unified manner the apparent Arrhenius, crossover and deeply supercooled regimes. The alpha relaxation event involves coupled cage-scale hopping and a long range collective elastic distortion of …
