混合態 型3能級原子與單模光場相互作用時原子的偶極壓縮效應
摘要：本文采用全量子理論，運用時間演化算符方法先求出所求系統任意時刻的.密度算符，和原子的約化密度矩陣，以及原子偶極壓縮的條件，數值計算地研究了混合態 型3能級與單模相干光場相互作用時原子的偶極壓縮效應。最後討論了原子初始的混合程度﹑相干光場的初始位相﹑光場的平均光子數﹑原子-場失諧量和偶合係數等對原子的偶極壓縮的影響。

Atomic dipole squeezing about mixed state -type atom of three-level and single-mode optical field coherent interaction
Abstract : In this paper, quantum theory, the use of time evolution operator obtained by the first method for the system density operator of any time, and atomic reduced density matrix, and the atomic dipole squeezing conditions, numerical study of the mixed state -type atom of the three-level with single-mode optical field coherent interaction of atomic dipole squeezing effect. Finally, the atomic initial mixing , Coherent Light Field , the initial phase of the light field average photon number , atom-field detuning and the amount of coupling coefficient of the atomic dipole compression effects were told.
Keywords : -type three-level atom; atom dipole squeezing; single-mode field; Density operator; reduced density matrix
