Abstract:
Two fully quantized generalized Jaynes-Cummings models for the interaction of a two-level atom with radiation field are treated,
one involving intensity dependent coupling and the other involving multiphoton interaction between the field and the atom.
The unitary transformation method presented here not only solves the time dependent problem but also allows a determination
of the eigensolutions of the interacting Hamiltonian at the same time.
