The relaxation dynamics of a simple glass former confined in a pore

We use molecular dynamics computer simulations to investigate the relaxation dynamics of a binary Lennard-Jones liquid confined in a narrow pore. We find that this dynamics is strongly influenced by the confinement in that time correlation functions are much more stretched than in the bulk. By investigating the motion of the particles as a function of their distance from the wall, we can show that this stretching is due to a spatial heterogeneity in the dynamics in that the relaxation time depends strongly on this distance.
