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…

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…

Continuous broadband Rydberg receiver using AC Stark shifts and Floquet States
Danni Song, Yuechun Jiao, Jinlian Hu +6
We demonstrate the continuous broadband microwave receivers based on AC Stark shifts and Floquet States of Rydberg levels in a cesium atomic vapor cell. The resonant transition fre…
