Electric field diagnostics in a continuous rf plasma using Rydberg-EIT
Bineet Dash, Xinyan Xiang, Dingkun Feng +2
We present a non-invasive spectroscopic technique to measure electric fields in plasma, leveraging large polarizabilities and Stark shifts of Rydberg atoms. Rydberg Stark shifts ar…

Effects of inert background gases and photo-illumination on three-color electromagnetically induced transparency of rubidium vapor
Alisher Duspayev, Bineet Dash, Georg Raithel
Three-color Rydberg electromagnetically induced transparency (EIT) of room-temperature Rb vapor in the presence of inert gases (Ar, Ne, and N) at 50~mTorr and 500~mTorr is inve…

Filter circuit for suppression of electric-field noise in Rydberg-atom experiments
Xinyan Xiang, Shuaijie Li, Alisher Duspayev +6
Rydberg atoms are widely employed in precision spectroscopy and quantum information science. To minimize atomic decoherence caused by dc Stark effect, the electric field noise at t…
