Rydberg-atom based radio-frequency electrometry using frequency modulation spectroscopy in room temperature vapor cells
Santosh Kumar, Haoquan Fan, Harald Kübler +2
Rydberg atom-based electrometry enables traceable electric field measurements with high sensitivity over a large frequency range, from gigahertz to terahertz. Such measurements are…
Atom-Based Sensing of Weak Radio Frequency Electric Fields Using Homodyne Readout
Santosh Kumar, Haoquan Fan, Harald Kübler +2
We utilize a homodyne detection technique to achieve a new sensitivity limit for atom-based, absolute radio-frequency electric field sensing of .…
Collective state synthesis in an optical cavity using Rydberg atom blockade
Santosh Kumar, Jiteng Sheng, Jonathon A. Sedlacek +2
We investigate the coherent manipulation of interacting Rydberg atoms placed inside a high-finesse optical cavity for the deterministic preparation of strongly coupled light-matter…
Observation and measurement of an extra phase shift created by optically detuned light storage in metastable helium
M. -A. Maynard, T. Labidi, M. Mukhtar +4
Electromagnetically induced transparency (EIT) in metastable helium at room temperature is experimentally shown to exhibit light storage capabilities for intermediate values of the…
Interacting double dark resonances in a hot atomic vapor of helium
S. Kumar, T. Lauprêtre, R. Ghosh +2
We experimentally and theoretically study two different tripod configurations using metastable helium (He*), with the probe field polarization perpendicular and parallel to the…
