Journal ArticleDOI
Elastically cooperative activated barrier hopping theory of relaxation in viscous fluids. I. General formulation and application to hard sphere fluids.
TL;DR: In this paper, the authors generalize the force-level nonlinear Langevin equation theory of single particle hopping to include collective effects associated with long range elastic distortion of the liquid, and construct a quasi-universal, fit-parameter-free theory for relaxation in thermal molecular liquids over 14 orders of magnitude in time.
Journal ArticleDOI
Elastically cooperative activated barrier hopping theory of relaxation in viscous fluids. II. Thermal liquids.
TL;DR: In this article, a quasi-universal theory for the alpha relaxation of thermal liquids based on mapping them to an effective hard sphere fluid via the dimensionless compressibility was proposed and implemented.
Journal ArticleDOI
Elastically Cooperative Activated Barrier Hopping Theory of Relaxation in Viscous Fluids. II. Thermal Liquids
TL;DR: The present work sets the stage for addressing distinctive glassy phenomena in polymer melts, and diverse liquids under strong confinement through a quasi-universal theory based on mapping them to an effective hard sphere fluid via the dimensionless compressibility.
Journal ArticleDOI
Elastically Cooperative Activated Barrier Hopping Theory of Relaxation in Viscous Fluids. I. General Formulation and Application to Hard Sphere Fluids
TL;DR: The present work provides a foundation for constructing a quasi-universal, fit-parameter-free theory for relaxation in thermal molecular liquids over 14 orders of magnitude in time.
Journal ArticleDOI
Unified Theory of Activated Relaxation in Liquids over 14 Decades in Time
TL;DR: In this paper, the authors 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.
