Millimeter Wave Imaging using Autler-Townes Splitting Induced Fluorescence from Rydberg Atoms in Rubidium Vapor
Gour Pati, Daniel Mechael, Frederik K. Fatemi +1
We demonstrate millimeter wave (mmWave) imaging using Autler-Townes (AT) splitting-induced fluorescence in rubidium vapor. By employing counter-propagating probe and coupling beams…

Dual-Frequency Absorption Spectroscopy in Laser-Cooled Rubidium Atoms: Theoretical Modeling and Experiment
Gour Pati, Mauricio Pulido, Fredrik K. Fatemi +2
We demonstrate dual-frequency absorption spectroscopy (DFAS) using laser-cooled 87Rb and 85Rb atoms. Doppler-free resonances with high-contrast are produced, which suggest the suit…

Spin-squeezed vector atomic magnetometry
Jinyang Li, Gour Pati, Renu Tripathi +1
Atomic magnetometers based on Zeeman shift measurement have the potential for high sensitivity and long-term stability. Like other atomic sensors including atomic clocks and atom i…
