Mode coupling behavior of a Lennard Jones binary mixture: a comparison between bulk and confined phases
arXiv:cond-mat/0510148 · doi:10.1063/1.2102869
Abstract
We present a quantitative comparison at equivalent thermodynamical conditions of bulk and confined dynamical properties of a Lennard Jones binary mixture upon supercooling. Both systems had been previously found to display a behavior in agreement with the Mode Coupling theory of the evolution of glassy dynamics. Differences and analogies of behavior are discussed focusing in particular on the role of hopping in reducing spatially correlated dynamics in the confined system with respect to the bulk.
