  The dynamics of the 2D Coulomb glass model is investigated by kinetic Monte
Carlo simulation. An exponential divergence of the relaxation time signals a
zero-temperature freezing transition. At low temperatures the dynamics of the
system is glassy. The local charge correlations and the response to
perturbations of the local potential show aging. The dynamics of formation of
the Coulomb gap is slow and the density of states at the Fermi level decays in
time as a power law. The relevance of these findings for recent transport
experiments in Anderson-insulating films is pointed out.
