A theory of the dephasing rate of quasi-2D free excitons due to acoustic phonon interaction at low exciton densities is presented. Both deformation potential and piezoelectric couplings are considered for the exciton-phonon interaction in quantum wells. Using the derived interaction Hamiltonian obta
