Exact Solution of Jaynes–Cummings Model Without Rotating Wave Approximation

Abstract

In coherent-state representation, the Jaynes–Cummings (JC) model in the absence of rotating wave approximation (RWA), i.e., in detuning case, is treated by the solution of some differential equations with constant coefficients and can be exactly solved. This approach can be easily extended to deal with the JC model without RWA in more complicated cases.
