摘要
根据Pegg和Barnett相位理论研究了与双原子相互作用的双模SU(1,1)相干场的相位特性 ,证明了光场每个模的相位及两个模的相位差均保持随机分布 ,给出了光场两个模的相位和方差的表达式 ,揭示了在适当的初始条件下 ,系统呈现原子的相干捕获现象。
The phase properties of two mode SU (1,1) coherent field interacting with two atoms are investingated by means of the phase formalism given by Pegg and Barnett. It is found that single mode phase and the difference of the two mode phase are all randomly distributed. The expressions of variance of the phase sum are presented. It is verified that the atomic coherent trapping will take place in a appropriate initial state of the system.
