Nonlinear response of a Kondo system: Perturbation approach to the time-dependent Anderson impurity model

Nonlinear tunneling current through a quantum dot (an Anderson impurity system) subject to both constant and alternating electric fields is studied in the Kondo regime. A systematic diagram technique is developed for perturbation study of the current in physical systems out of equilibrium governed by time-dependent Hamiltonians of the Anderson …
