TY - JOUR A1 - Díaz Sánchez, Anastasio AU - Pérez Garrido, Antonio T1 - Stretched exponential relaxation in the Coulomb glass Y1 - 2002 SN - 1434-6036 UR - http://arxiv.org/abs/cond-mat/0006396 UR - http://hdl.handle.net/10317/579 AB - 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) = f0 exp −(t/ ) , with the exponent increasing with the temperature. The relaxation time follows an Arrhenius behavior divergence when T → 0. A relation between the specific heat and the entropy in the long time regime is found.
