Generalized Bloch equations for a strongly driven tunneling system
arXiv:cond-mat/9605092 · doi:10.1103/PhysRevE.55.2195
Abstract
Using the Robertson projection operator formalism, we derive generalized Bloch equations which describe the dynamics of a biased two-level tunneling system strongly driven by an external field and weakly coupled to a super-Ohmic heat bath. The generalized Bloch equations constitute a set of coupled nonlinear integro-differential equations. With their help we investigate the influence of phonons on the phenomenon of dynamical localization.
