| 摘 要： | 讨论了囚禁离子与两驻波场相互作用时的量子相干性.在大失谐的条件下,离子的振动能量呈现崩塌-回复的相干性特征,表明离子的振动态具有压缩效应.无量纲压缩参数G3愈大,囚禁离子的振动态压缩效应愈显著.进一步增大参数G3,所能得到的最大压缩反而减小.

| Abstract: | The quantum dynamics of a trapped ion which acts with two standing light fields with different frequency is investigated on the condition of high detuning. Evolution of the quantum mean energy of the ion with time displays the characteristic of collapse revival which implies the vibration states of the ion have squeezing effect. The higher the value of the squeezing parameter G 3 . The higher the degree of squeezing of the vibration states of the ion can be observed. If G 3 is greater than a particular value, the degree of squeezing will become smaller. |
