Abstract
The rotating wave approximation (RWA) plays a central role in the quantum dynamics of two-level systems. We derive corrections to the RWA using the renormalization group approach to asymptotic analysis. We study both the Rabi and Jaynes-Cummings models and compare our analytical results with numerical calculations.
