摘要
运用量子信息熵理论,研究了双模压缩真空态与运动原子相互作用中,运动原子的信息熵压缩。讨论了运动原子初态处于任意态时,原子运动速度、场模结构和场压缩参量对原子信息熵压缩的影响。结果表明,通过选择原子初态,原子运动速度、场模结构,场压缩因子和场压缩相位角可以分别控制原子信息熵压缩的偶极矩分量值、压缩频率、压缩幅度和压缩方向。选择适当的系统参量,运动原子可呈现长时间的持续熵压缩。原子初态的混合度对运动原子的信息熵压缩几乎没有影响。
Abstract
The information entropy squeezing properties of the atom in motion interacting with the two-mode squeezing vacuum field via two-photon transition are studied by means of quantum theory. The influences of the velocity of atomic motion,the field structure and the parameter of squeezing field on the information entropy squeezing properties of the atom are investigated as the initial atom is in any state. The results indicate that the value of squeezed component of the atomic dipole,squeezed frequency,amplitude and squeezed direction of the atomic information entropy can be controlled by choosing the atomic initial state,the velocity of atomic motion,the field structure and the squeezing factor of field and the squeezing phase angle of the field,respectively. In the longer time,squeezing effects of the atom in motion can be obtained by choosing the system parameters. The mixing degree of atomic initial state has no influence on the entropy squeezing of the atom in motion.
