Breakdown of the Stokes-Einstein relation in two, three, and four dimensions
Breakdown of the Stokes-Einstein relation in two, three, and four dimensions
The breakdown of the Stokes-Einstein (SE) relation between diffusivity and viscosity at low temperatures is considered to be one of the hallmarks of glassy dynamics in liquids. Theoretical analyses relate this breakdown with the presence of heterogeneous dynamics, and by extension, with the fragility of glass formers. We perform an …
