COULOMB GLASS SIMULATIONS - CREATION OF A SET OF LOW-ENERGY MANY-PARTICLE STATES, NONERGODIC EFFECTS IN THE SPECIFIC-HEAT

We have implemented a new numerical method to obtain the low-energy ma ny-particle states of the Coulomb glass. First, this method creates an initial set of low-energy states by a hybrid of local search and simu lated annealing approaches. Then, systematically investigating the sur roundings of the states found. this set is completed. The transition r ates between these states ari, calculated. The connectivity of the cor responding graph is analyzed in dependence on temperature and duration of measurement. We study how the formation of clusters is reflected i n the specific heat as non-ergodic effects.
