Single particle dynamics of a confined Lennard–Jones mixture in the supercooled regime

Dynamical properties of a supercooled Lennard–Jones binary mixture in a disordered array of soft spheres are studied by computer simulation close to the Mode Coupling Theory crossover temperature Tc. Predictions of the MCT are satisfied by the confined liquid. The b exponent of the von Schweidler law, the γ exponent and Tc are evaluated for both species. The range of validity of the theory shrinks and a substantial enhancement of hopping processes are observed above Tc with respect to the bulk.
