Abstract:

The relaxation of the specific heat and the entropy to their equilibrium values is investigated numerically for the three-dimensional Coulomb glass at very low temperatures. The long time relaxation follows a stretched exponential function, f (t) = f 0exp - (t/τ)β , with the exponent β increasing with the temperature. The relaxation time diverges as an Arrhenius law when T→ 0.
