Beschreibung:
We study the dynamical behavior of disordered many-particle systemswith long-range Coulomb interactions by means of damage-spreadingsimulations. In this type of Monte-Carlo simulations one investigates thetime evolution of the damage, i.e. the difference of the o ccupationnumbers of two systems, subjected to the same thermal noise. We analyzethe dependence of the damage on temperature and disorder strength. Forzero disorder the spreading transition coincides with the equilibrium phasetransition, whereas for finite disorder, we find an evidence for a dynamicalphase transition well below the transition temperature of the pure system.
