| 摘 要： | 通过求解系统的Milburn方程,研究了两能级原子与双模SU(1,1)相干态光场相互作用系统的量子统计性质,分析了内禀退相干、双模光子数差和平均光子数对量子统计性质的影响.结果表明,内禀退相干增强了光场两模的聚束效应和模间相关程度,并使第一模始终处于亚泊松分布;存在内禀退相干时,场的二阶相干度仍具有明显的崩塌-回复现象,随着时间的演化,光场第一模处于亚泊松分布,光子呈现反聚束效应,光场两模间呈正相关,且为非经典相关,而在大部分时间区域,光场第二模处于泊松分布,光子呈现聚束效应.

| Abstract: | The quantum statistical properties in the system of a two-mode SU(1,1)coherent field interacting with a two-level atom are investigated by solving Milburn equation.The effects on the quantum statistical properties induced by the intrinsic decoherence,the two-mode photon number and the mean photon number are analyzed.The results show that the intrinsic decoherence strengthens the anti-bunching effect of the two-mode and the correlation intensity between the two modes and makes the first mode of the field alw... |
