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…
Recent advances in Ultralong-range Rydberg molecules
Jingxu Bai, Yuechun Jiao, Xiao-Qiang Shao +2
Rydberg molecule, formed by one or more Rydberg atoms, exhibits remarkable properties, including an exceptionally large spatial extent, rich rovibrational level structures, permane…
Thermal resonance-enhanced transparency in room temperature Rydberg gases
Jinlian Hu, Yuechun Jiao, Yuwen Yin +6
We report the enhanced optical transmission in the coherent, off-resonant excitation of Rydberg atom gases at room temperature via a two-photon process. Here thermal resonance-enha…
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…
Measurements of the hyperfine structure of Rydberg states by microwave spectroscopy in Cs atoms
Rong Song, Jingxu Bai, Zhenhua Li +3
We present measurements of hyperfine structure (HFS) of the Rydberg states for large principal quantum number range () employing the microwave spectroscopy in a…
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…
