非线性囚禁离子模型中振幅平方压缩效应
Amplitude-squared squeezing effects in nonlinear trapped ion model
摘要
Abstract
Based on the nonlinear Jaynes-Cummings model,the amplitude squared squeezing effect of the center-of-mass motion of the ion driven by a single of standing wave field was studied.The results show that the nonlinear parameter η has a great influence on the compression time,namely,when the parameter η increases,the duration time of squeezing grows and the squeezing degree is deeper; But when η reaches a critical value,the maximum amount of squeezing decreases,the compression time becomes relatively shorter.In addition,the phase of the standing wave field also shows a significant influence on the squeezing effect.关键词
