Strong antibunching photons/photon pairs emission in two atoms cavity QED system with the Van der Waals interaction
Zhouyang Yu, Jinping Xu, Chengjie Zhu +2
Weinvestigate the generation of antibunching photons and photon pairs in a two-atom cavity QED system leveraging interatomic van der Waals (vdW) interaction. We show that the vdW i…
Ergodicity breaking from Rydberg clusters in a driven-dissipative many-body system
Dong-Sheng Ding, Zhengyang Bai, Zong-Kai Liu +4
It is challenging to probe ergodicity breaking trends of a quantum many-body system when dissipation inevitably damages quantum coherence originated from coherent coupling and disp…
Dephasing of ultracold cesium -Rydberg Electromagnetically Induced Transparency
Yuechun Jiao, Liping Hao, Jingxu Bai +5
We study Rydberg electromagnetically induced transparency (EIT) of a cascade three-level atom involving 80 state in a strong interaction regime employing a cesium ultracol…
Accessing and Manipulating Dispersive Shock Waves in a Nonlinear and Nonlocal Rydberg Medium
Chao Hang, Zhengyang Bai, Weibin Li +2
Dispersive shock waves (DSWs) are fascinating wave phenomena occurring in media when nonlinearity overwhelms dispersion (or diffraction). Creating DSWs with low generation power an…
