摘要
研究存在Kerr介质时,耦合双原子与单模压缩真空场双光子跃迁相互作用系统平均光子数的时间演化规律,讨论Kerr介质与光场的耦合强度和原子间偶极-偶极相互作用对平均光子数的影响.
The time evolution of the average photon number in the interaction system of two coupling atoms with squeezed vacuum field via two-photon transition in Kerr medium are studied by means of quantum theory. The influences of the Kerr medium and field coupling constant and the dipole-dipole interaction between atoms on the average photon number are discussed.
