Rydberg atom reception of a handheld UHF frequency-modulated two-way radio

February 10, 2026

Author(s)

Noah Schlossberger, Tate McDonald, Nikunjkumar Prajapati, Christopher Holloway

Rydberg atoms, due to their large polarizabilities and strong transition dipole moments, have been utilized as sensitive electric field sensors. While their...

Atomic and molecular systems for radiation thermometry

January 15, 2026

Author(s)

Stephen Eckel, Christopher Holloway, Eric Norrgard, Nikunjkumar Prajapati, Noah Schlossberger, Matthew Simons

Atoms and simple molecules are excellent candidates for new standards and sensors because they are both all identical and their properties are determined by the...

Two-dimensional imaging of electromagnetic fields via light sheet fluorescence imaging with Rydberg atoms

November 24, 2025

Author(s)

Noah Schlossberger, Tate McDonald, Kevin Su, Rajavardhan Talashila, Robert Behary, Charles L. Patrick, Eugeniy E. Mikhailov, Seth Aubin, Irena Nokivoka, Christopher Holloway, Nikunjkumar Prajapati

Imaging of electric and magnetic fields is limited by the fact that conventional field probes rely on conductive elements that perturb the fields they are meant...

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

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

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
