研究了一个二能级里德伯原子在计及原子散射的二级修正项时,与单模热光场双光子相互作用系统中光子的反聚束效应,着重讨论了非线性修正项,双光子失谐量以及热噪声对光子反聚束效应的影响.The effects of photon antibunching in the interaction system of a two-level Rydberg atom with a single-mode thermal field via two-photon processes are studied, by considering the second-order correction of atomic scattering. The influences of the nonlinear correction term, the two photon frequency detuning and the thermal noise on the photon antibunching are discussed.
