GENERATION OF EVEN AND ODD COHERENT STATES IN THE INTENSITY-DEPENDENTJAYNES-CUMMINGS MODEL

We study the evolution of the wavefunction in the intensity dependent Jaynes-Cummings model. It is shown that apart from the periodic reviva ls indicated by the dynamics of inversion, half-time revivals of the w avefunction take place in the limit of ($) over bar n much greater tha n 1. The decoupled atomic state is a superposition of the upper and lo wer levels and is independent of the initial atomic condition. The dec oupled field state is an even or odd coherent state with a spiked dist ribution function, depending on the initial atomic state.
