Sagnac Tractor Atom Interferometer on Photonic Integrated Circuit
Lefeng Zhou, Anne Graf, Georg Raithel
We study the theory of, and propose an experimental design for, a Sagnac tractor atom interferometer based on a photonic integrated circuit (PIC). The atoms are trapped in counter-…
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…
Hyperfine structure and collisions in three-photon Rydberg electromagnetically induced transparency
Alisher Duspayev, Georg Raithel
Multi-photon electromagnetically-induced transparency (EIT) of atomic vapors involves several intermediate atomic levels. The sub-structure of these levels and their collisional in…
