Time-dependent renormalization was employed to derive a nonlinear quantum master equation (QME), in which the dynamics of a non-equilibrium fluctuation in an irrelevant system are fed back into that of a relevant one. In terms of application, the nonlinear QME was formulated from the viewpoint of the conventional theory for weak electronic coupling and analyzed numerically. In the case of a large energy gap between sites in the relevant system and the reorganization energy, the new equation reproduced the results obtained through numerically exact calculations; this behavior is in contrast with that of the conventional theory.
