The fluctuation–dissipation theorem tells us that is a function of the thermal fluctuations of the dipole moment of the system. We calculate X numerically for three–dimensional Coulomb glasses as a function of temperature and frequency. %K Física Aplicada %K Cristales Coulomb %K Susceptibilidad electrica %~ GOEDOC, SUB GOETTINGEN
