The effective action for a generalized Jaynes--Cummings model
The effective action for a generalized Jaynes--Cummings model
We describe an effective field theory for atomic lasers which reduces to the Jaynes-Cummings model in the non-relativistic, single mode limit. Our action describes a multi-mode system, with general polarizations and Lorentz invariance and can therefore be used in all contexts from the astrophysical to the laboratory. We show how …
