摘要:

本文从理论上研究了腔QED系统中的三光子阻塞现象。在同相辐射的情况下,我们表明,三光子封锁与聚束的两个光子可以实现在一个小的制度的驱动场拉比频率。而在异相辐射情况下,由于相消干涉的存在,单光子激发被抑制,在较宽的驱动场拉比频率范围内可以实现三光子阻断。此外,三光子阻断现象可以得到显著改善。结果表明,这种双原子方案是实现反聚束光子对的一个很好的候选方案。

英文摘要:

We theoretically investigate the three-photon blockade phenomenon in a two atoms cavity QED system, where two atoms are driven by a coherent field. In the case of in-phase radiations, we show that the three-photon blockade with bunched two photons can be realized in a small regime of the driving field Rabi frequency. However, in the case of out-of-phase radiations, the one-photon excitations are prohibited due to the destructive interference, and three-photon blockade can be realized in a wide regime of driving field Rabi frequency. In addition, the three-photon blockade phenomenon can be significantly improved. The results presented here show that this two-atom scheme is a good candidate to achieve anti-bunched photon pairs.
