Viscous Flow and Jump Dynamics in Molecular Supercooled Liquids: II Rotations
Cristiano De Michele, Dino Leporini
Abstract
The rotational dynamics of a supercooled molecular liquid is investigated by a molecular-dynamics numerical study. We detect rotational jumps with a waiting-time distribution which is well fitted by a truncated power law. At lower temperatures the rotational correlation times are decoupled from the viscosity.
