Abstract
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 T-c Predictions of the MCT are satisfied by the confined liquid. The b exponent of the von Schweidler law, the gamma exponent and T-c are evaluated for both species. The range of validity of the theory shrinks and a substantial enhancement of hopping processes are observed above T-c with respect to the bulk. (C) 2002 Elsevier Science B.V.
