✦ Synopsis

We search for the phase transition and the nature of the low temperature phase for different models of the Coulomb glass and different dimensionalities. We do this with the help of several statistical parameters of the overlap between different many-particle states, first introduced to investigate the spin glass transition and related to the Edwards-Anderson order parameter. We calculate numerically these parameters in dependence on the temperature and system size for very low temperatures. Then we apply scaling analysis to these parameters.
