摘要:

对于单光子能级上的无耗散光子-光子相互作用,我们利用双光子波函数分析了三能级原子中光子对诱导的单光子跃迁和双光子跃迁。我们发现,通过调节光子对的时间相关性,可以显著增强双光子吸收。我们研究了两种典型情况:高斯波函数和矩形波函数。在后者中,我们发现在特定条件下,单光子跃迁被完全抑制,而双光子跃迁的几率仍然很高。

英文摘要:

For dissipation-free photon-photon interaction at the single photon level, we analyze one-photon transition and two-photon transition induced by photon pairs in three-level atoms using two-photon wavefunctions. We show that the two-photon absorption can be substantially enhanced by adjusting the time correlation of photon pairs. We study two typical cases: Gaussian wavefunction and rectangular wavefunction. In the latter, we find that under special conditions one-photon transition is completely suppressed while the high probability of two-photon transition is maintained.
