Tavis-Cummings模型系统中光场的相位特性

Phase Properties of Light in the Tavis-Cummings Model

本文应用全量子理论研究了单模强相干光场与两个全同的二能级原子相互作用的Tavis－Cummings（T－C）模型系统中光场相位的演化特性．具体计算了光场厄米相位算符的期望值、相位概率分布及相位涨落，并讨论了原子间的偶极相互作用和原子的初始相干性对光场相位性质的影响．

Based on the quantum theory, the properties of phase evolution of thelight field in the Tavis-Cummings model system of the two identical two-level atomscoupling to a single-mode strong coherent light are studied. The expectation valuesof the phase operator, the phase probability distribution and the fluctuation are cal-culated. The influence of the dipole-dipole interaction between atoms and influenceof the atomic polarization factors on the phase properties of the light are discussed.
