Rydberg-Mediated Nonlinear Quantum Optics
Yun-Hui He, Chang-Cheng Li, Xu Shen +5
Rydberg atoms have emerged as a versatile platform for quantum optics due to their exaggerated properties, particularly their strong long-range interactions, which enable a new reg…
Doppler-enhanced superheterodyne Rydberg microwave receiver
Yuwen Yin, Ruimin Chen, Shibing Ji +7
We report the enhanced sensitivity of the Rydberg microwave (MW) receiver by exploiting the Doppler effect in a vapor cell. A two-photon Rydberg ladder scheme is implemented via th…
Reciprocal Floquet thermalization in one-dimensional Rydberg atom array
Yunhui He, Yuechun Jiao, Jianming Zhao +1
Periodically driven Floquet quantum systems hold great promise for engineering exotic quantum phases and matter, but are often limited by rapid thermalization. In this work, we pro…
Arbitrary Instantaneous Bandwidth Microwave Receiver via Scalable Rydberg Vapor Cell Array with Stark Comb
Yuechun Jiao, Yuwen Yin, Yunhui He +7
Rydberg atoms have great potential for microwave (MW) measurements due to their high sensitivity, broad carrier bandwidth, and traceability. However, the narrow instantaneous bandw…
Observation of electric field induced superradiance slowdown in ultracold Rydberg atomic gases
Yunhui He, Jingxu Bai, Yuechun Jiao +2
Atoms excited to electronically high-lying Rydberg states decay to low-energy states through spontaneous emission processes. We investigate the impact of a static electric field on…
