| 摘 要： | 研究了双模压缩真空场与V型三能级运动原子的相互作用,得到光场二阶相干度和模间相干度的解析表达式;通过数值计算分析了原子运动速度、场模结构参数和平均光子数对光场二阶相干度和模间相干度的影响.结果表明:平均光子数的增加使得二阶相干度和模间相干度显著增大;而原子运动速度、模场结构参数的增加虽然对光子聚束效应和反聚束效应的强度影响不大,却使其演化周期大大减小.

| Abstract: | two-mode squeezed vacuum field interacting with a V-type three-level moving atom is investigated. We can get analytic expressions of second-order correlation function and two-mode correlation function. The influence of atomic motion, the field structure and intensity of photons on second-order correlation function and two-mode correlation function are obtained by numerical calculation. The results indicate that correlation function and photon bunching increase obviously when intensity of photons increase; photon bunching and antibunching don't change when atomic motion and the field structure increase, but the period of photon bunching and antibunching reduce greatly. |
