GENERATION OF HIGHER-ORDER ATOMIC-DIPOLE SQUEEZING IN A 2-PHOTON JAYNES-CUMMINGS MODE

In this paper, the concept of higher-order atomic-dipole squeezing (HO ADS) has been introduced, and we have, as an example, studied ii; in a two-photon Jaynes-Cummings model which could generate second-order at omic-dipole squeezing (SOADS). Theoretical studies have shown that HOA DS could also be achieved in this model when it is restricted to the f ollowing initial condition: the field in a thermal state and the atom in a proper coherent superposition of states. In details, we have disc ussed the influence of initial atomic coherence or thermal photons on HOADS, and the important connection of HOADS with second-order squeezi ng effects.
