• amorphous semiconductors
• Coulomb glasses
• Numerical simulations
• Many-particle density of states

In this paper, we investigate some many-particle equilibrium properties of the Coulomb glass model to deepen into the thermal behavior of glassy chalcogenides. Concretely, we focus on the dependence of the energy on the temperature, the many-particle density of states and the absorbed and emitted power. The results show an interesting conclusion: at very low temperatures, the effect of soft transitions, called soft dipoles, is dominant, which gives the material its characteristic glassy behavior, characterized by slow dynamical rates.
