Abstract

We develop a superoperator coupled cluster method for nonequilibrium open many-body quantum systems described by the Lindblad master equation. The method is universal and applicable to systems of interacting fermions, bosons or their mixtures. We present a general theory and consider its application to the problem of quantum transport through the system with electron-phonon correlations. The results are assessed against the perturbation theory and nonequilibrium configuration interaction theory calculations.
