Linearization of the multiphoton single-atom Dicke Hamiltonian
Avia Rosenhouse, Jacob Katriel · Physical Review A · 1990
The multiphoton single-atom Dicke Hamiltonian in the dipole and the rotating-wave approximations is shown to reduce to the one-photon single-atom Dicke Hamiltonian via an approximate linearization process. For the special case of the Jaynes-Cummings Hamiltonian, it is shown that it is possible to derive a linearized form that is exactly equal to the original Hamiltonian.
