Nonclassical Properties in Non-degenerate Two-photon Jaynes-Cummings Model

Abstract

Abstract: The nonclassical properties (such as antibunching effect, violation of Cauchy-Schwarz inequality and two-mode squeezing) of the pair coherent states based on a non-degenerate two-photon Jaynes-Cummings model were investigated. It is shown that these nonclassical properties can be enhanced in the case that the coefficients are chosen appropriately or that the atom is selectively detected. In addition, it seems that all kinds of the nonclassical properties (including antibunching effect and violation of Cauchy-Schwarz inequality)by using -type three-level atom are more effective than that using -type three-level atom.

Key words: quantum optics, nonclassical properties, non-degenerate two-photon Jaynes-Cummings model, pair coherent states
