Abstract

We consider Brownian particles diffusing in an external potential which grows at long distance as x^\alpha, 0<\alpha<1.  We show that the relaxation to the Gibbs steady-state is anomalous, with stretched exponential relaxation.  We calculate the spatial dependence of this slowly relaxing distribution characterizing the approach to equilibrium.
