High-angular-momentum Rydberg states in a room-temperature vapor cell for DC electric-field sensing

Alisher Duspayev, Ryan Cardman, David A. Anderson +1

We prepare and analyze Rydberg states with orbital quantum numbers using three-optical-photon electromagnetically-induced transparency (EIT) and radio-frequency (RF) d…

Rydberg-EIT of Rb vapor in a cell with Ne buffer gas

Nithiwadee Thaicharoen, Ryan Cardman, Georg Raithel

We investigate Rydberg electromagnetically induced transparency (EIT) of Rb atomic vapor in a glass cell that contains a 5-Torr neon buffer gas. At low probe power, EIT line…

Dynamic polarizability of the Rb -state in 1064 nm light

Alisher Duspayev, Ryan Cardman, Georg Raithel

We report a measurement of the dynamic (ac) scalar polarizability of the state in Rb atoms at a laser wavelength of 1064~nm. Contrary to a recent measurement in P…

Photoionization of Rydberg Atoms in Optical Lattices

Ryan Cardman, Jamie MacLennan, Sarah E. Anderson +2

We develop a formalism for photoionization (PI) and potential energy curves (PECs) of Rydberg atoms in ponderomotive optical lattices and apply it to examples covering several regi…

Atom radio-frequency interferometry

David A. Anderson, Rachel E. Sapiro, Luís F. Gonçalves +2

We realize and model a Rydberg-state atom interferometer for measurement of phase and intensity of radio-frequency (RF) electromagnetic waves. A phase reference is supplied to the…

Measurement of the hyperfine coupling constant for Rydberg states of Rb

Andira Ramos, Ryan Cardman, Georg Raithel

We present measurements of the hyperfine structure splittings of Rydberg states of Rb for = 43, 44, 45 and 46. From the splittings, the hyperfine coupling cons…
