Phase Properties of the Field in Two-photon J-C Model in a Kerr-like Medium

本文运用Ｐｅｇｇ－Ｂａｒｎｅｔｔ厄米相位公式［１，２］，研究了类克尔媒质中双光子Ｊ－Ｃ模型腔场的相位特性，讨论了双光子Ｊ－Ｃ模型腔场相位几率分布、相位算符期待值和相位涨落的演变；研究了类克尔媒质与腔场的非线性作用对腔场相位特性的影响。

in this paper, the phase properties of the cavity field of the two-photon J-C model in a kerr-like medium are studied by means of the Pegg-Barnett hermitian phase formals[1,2]. The time evolution of the phase probability distribution, the phase operator expectation value and the phase fluctuation are obtained. The effect of nonlinear interaction of a kerr-like medium on the phase properties is analyzed by comparing with the two-photon J-C model.
