We have studied single electron charge relaxation and dephasing rates in laterally coupled GaAs double quantum dot due to electron-phonon interaction. We first calculate the single electron wavefunctions in the double dot using a basis formed by the Fock-Darwin states. For the electron-phonon interaction we include both deformation potential and piezoelectric coupling. Our results show strong dependence of the relaxation and dephasing rates on interdot distance, confinement strength, and interdot bias.
