THE INTERACTION REPRESENTATION AND NONADIABATIC CORRECTIONS TO ADIABATIC EVOLUTION OPERATORS .2. NONLINEAR QUANTUM SYSTEMS

摘要

This paper reports further applications of the recently developed interaction representation form of infinite order operator corrections to adiabatic evolution operators. Previous work derived the form of the correction, and applied the methodology to a bilinearly coupled system bath model. In this paper we present results on coupled quantum systems in which the coupling is highly nonlinear. The method is both easy to implement and numerically accurate.
