非线性囚禁离子振动模式互关联函数的研究
Study on cross correlation function of vibrational modes of nonlinear trapped ions
摘要
Abstract
In order to study the influence of nonlinear parameters on the cross-correlation function of two vibrational modes of the trapped ions along mutually orthogonal directions, the exact solution of the nonlinear double-photon Jaynes-Cummings model which describes the interaction between a single two-dimension three-level trapped ion and two classical standing wave lasers was obtained by theoretical analysis and numerical computation.The cross-correlation function of two vibrational modes of the trapped ion was analyzed numerically. The results show that the anticorrelation effect is strengthened at first and then weakened with the increasing of the Lamb-Dicke parameters when initial average quantum number is small.But the correlated effect is always strengthened with the increase of the Lamb-Dicke parameters.The anticorrelation effect will be weakened and then disappear with the increasing of initial average quantum number.The initial average quantum number and Lamb-Dicke parameters characterized by nonlinear effects have obvious influence on cross correlation.关键词
