摘要
本文利用Pegs-Barnett位相理论,通过考察一“V”型三能级原子与光场相互作用系统中,光场位相随时间演化的规律,证明了在一定的初始状态下,原子会出现相干捕获现象。
In this paper, we have investigated the time evolution of the phase operatorsof the radiation field in the system containing a 'V' type three-level atom inter-acting with a two-mode field by means of the new formlism describing the phaseproperties given by Pegg and Barnett. It has been verified that the atomic coherenttrapping will happen in an appropriate initial state of the system.
