Radio-Frequency plane-wave angle of arrival determination from Stark-shifted EIT spectra

Author(s)

Rajavardhan Talashila, Zoya Popovic, Nikunjkumar Prajapati, Noah Schlossberger, Chris Holloway

This work demonstrates a novel method for determining the Angle of Arrival (AoA) of RF fields using AC Stark shifting characteristics. Unlike conventional AoA techniques, this method does not require

Floquet Interpretation of Avoided Crossings in AC Stark-Shifted Rydberg-EIT Spectra

Author(s)

Rajavardahn Talashila, Nikunjkumar Prajapati, Noah Schlossberger, Chris Holloway

We present a combined experimental and Floquet-theoretical study of avoided crossings in the AC Stark-shifted electromagnetically induced transparency (EIT) spectra of Rydberg atoms. Using the Shirley

Characteristics of VHF and UHF band detection using Stark shifting in Rydberg-atom sensors

Author(s)

Rajavardhan Talashila, Noah Schlossberger, Nikunjkumar Prajapati, Christopher Holloway

We present a characterization of the sensitivity of broadband field measurements in VHF and UHF bands using AC stark shifting of the Rydberg states. The dependence of the sensitivity and dynamic range
