Vapor-Cell-Induced Uncertainty in Rydberg Atom Measurements via the Electric-Field Volume-Integral-Equation Method

Martin Stumpf, William J. Watterson, Rajavardhan Talashila +5

Electromagnetic scattering effects of a vapor cell on electric-field measurements using Rydberg atom-based sensors are analyzed with the aid of the volume integral equation method.…

Resolving magnetic-sublevel structure in Rydberg Autler-Townes spectra with arbitrary RF polarization

Noah Schlossberger, Rajavardhan Talashila, Stone B. Oliver +3

We investigate the role of magnetic sublevels in Autler-Townes spectra of Rydberg atoms driven by radio-frequency (RF) fields with arbitrary polarization. While conventional treatm…

Frequency Comb Behavior of Time Crystals in an RF-Driven Dissipative Rydberg System

Dixith Manchaiah, William J. Watterson, Christopher L. Holloway

Driven nonlinear oscillators constitute a universal paradigm for understanding synchronization, frequency pulling, and frequency comb formation in nonequilibrium systems. Here, we…

An Imaging Radar Using a Rydberg Atom Receiver

William J. Watterson, Nikunjkumar Prajapati, Rodrigo Castillo-Garza +5

Rydberg atoms in a gas form are highly sensitive electric field probes capable of detecting and measuring the amplitude, phase, and polarization of broadband time-varying signals.…

Determining angle of arrival of radio frequency fields using subwavelength, amplitude-only measurements of standing waves in a Rydberg atom sensor

Rajavardhan Talashila, William J. Watterson, Benjamin L. Moser +6

Deep subwavelength RF imaging with atomic Rydberg sensors has overcome fundamental limitations of traditional antennas and enabled ultra-wideband detection of omni-directional time…

Primary quantum thermometry of mm-wave blackbody radiation via induced state transfer in Rydberg states of cold atoms

Noah Schlossberger, Andrew P. Rotunno, Stephen P. Eckel +14

Rydberg states of alkali atoms are highly sensitive to electromagnetic radiation in the GHz-to-THz regime because their transitions have large electric dipole moments. Consequently…
