Dissipation in Open Two-Level Systems: Perturbation Theory and Polaron Transformation
arXiv:cond-mat/0207256 · doi:10.1142/9789812777843_0054
Abstract
We compare standard perturbation theory with the polaron transformation for non-linear transport of electrons through a two-level system. For weak electron-phonon coupling and large bias, there is good agreement between both approaches. This regime has recently been explored in experiments in double quantum dots.
