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,
, with the exponent β
increasing with the temperature. The relaxation time diverges as an Arrhenius
law when
