Collapse and revival phenomena in the many-atom-jaynes-cummings model in the presence on initial fock- and coherent-state fields

Abstract

New aspects of cooperative radiation inhibition effects appearing in the interaction of many two-level atoms with a resonant single-mode radiation field inside a lossless cavity are examined. It is shown that collapses and revivals of the envelopes of Rabi oscillations of atomic energy expectation value occur in the presence of initial strong Fock-state fields. In the case of initial coherent fields, a cooperative energy shift of the quasi-stationary energy expectation value is pointed out. Further it is found that all cooperative radiation effects are caused by strong atom-atom correlations.
