GENERATION OF HIGHER-ORDER ATOMIC DIPOLE SQUEEZING IN HIGH-Q MICROMASER-CAVITY

In this paper, we have introduced the concept of higher-order atomic d ipole squeezing (HOADS) and have, as an example, applied it to a quant um optical model known as Jaynes-Cummings model (JCM) which could gene rate second-order atomic dipole squeezing (SOADS). We have shown that the JCM could also generate HOADS when it is restricted to the followi ng initial condition: the field in a thermal state and the atom in an appropriate coherent state. We have studied in detail the influence of initial atomic coherence or thermal photons on HOADS, the important c onnection of HOADS with SOADS and second-order field squeezing (SOFS), and the possibility of realization of HOADS in micromaser experiments with Rydberg atoms in a high-Q cavity.
