摘要
Applying the method of coherent-state orthogonalization expansion, the energy spectra and the dynamical properties of the Jaynes-Cummings model with non-rotating wave approximation are calculated exactly. By comparison with the approximate analytical solutions, it is found that the approximate analytical solutions agree with our numerical exact solutions well both in weak coupling regime and in strong coupling regime, but not so well in intermediate strength coupling regime.
