Stretched Exponential Relaxation for Brownian Particles
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.

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.
