  Rotating wave approximation example other than Jaynes Cumming model

+ 3 like - 0 dislike
917 views

Is the rotating wave approximation only valid in the interaction picture?

In the Jaynes-Cumming model, the interaction Hamiltonian is simplified in the rotating wave approximation. Is the rotating wave approximation needed in deriving a master equation which does not involve the Jaynes-Cumming interaction Hamiltonian?

The rotating wave approximation is used not only in the(original) Jaynes–Cummings model - which is just one of the simplest models where it applies - but whenever a particular influential frequency must be cancelled analytically. Thus it is always used in combination with the interaction picture.
