Abstract

We study the effect of long-range Coulomb interaction on the dipole matrix elements in strongly disordered electron glass. The average dipole matrix element is computed numerically by a self-consistent Hartree-Fock approximation. For distances greater than the localization length the majority of dipole matrix elements decay exponentially with a dipole size. Mott states give rise to dipoles with a size much longer than the localization length.
