Angle-of-Arrival Determination of Radio-Frequency Fields Using Stark-Shifted Rydberg-EIT Spectra
Rajavardhan Talashila, Zoya Popovic, Nikunjkumar Prajapati +2
We demonstrate a method for determining the magnitude of the angle of arrival (AoA) of a linearly polarized radio-frequency (RF) field using the angle-dependent spectral amplitudes…
Floquet Interpretation of Avoided Crossings in AC Stark-Shifted Rydberg-EIT Spectra
Rajavardhan Talashila, Nikunjkumar Prajapati, Noah Schlossberger +1
We present a combined experimental and Floquet-theoretical study of avoided crossings in the AC Stark-shifted electromagnetically induced transparency (EIT) spectra of Rydberg atom…
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…
MHz to sub-kHz field detection with an all-dielectric potassium Rydberg-atom sensor
Daniel Hammerland, Rajavardhan Talashila, Dixith Manchaiah +8
Rydberg sensors have significant promise as an alternative to the antenna systems used for sub-MHz frequency communications, where the scale of high-efficiency antennas is often im…
Uniqueness Theorem: With Normal Components Specified on External Spherical Surface
Rajavardhan Talashila
A uniqueness theorem for time-harmonic electromagnetic fields which requires the normal components of electromagnetic fields specified on a spherical surface is proposed and proved…
Sensitivity Comparison of Rydberg Atom-Based Radio-Frequency Electric Field Detection: Ionization Current Versus Optical Readout
Dangka Shylla, Rajavardhan Talashila, Alexandra Artusio-Glimpse +7
We investigate a technique for detecting radio-frequency (RF) electric fields in a Cesium (Cs) vapor cell at room temperature by collecting charge from ionized Rydberg atoms and co…
Angle-of-arrival detection of radio-frequency waves via Rydberg atom fluorescence imaging of standing waves in a glass vapor cell
Noah Schlossberger, Rajavardhan Talashila, Nikunjkumar Prajapati +1
We present a method for measuring the angle-of-arrival of 40 GHz radio-frequency (RF) radiation by mapping the standing waves generated in a rectangular glass vapor cell. These sta…
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…
Imaging of induced surface charge distribution effects in glass vapor cells used for Rydberg atom-based sensors

We demonstrate the imaging of localized surface electric (E) field effects on the atomic spectrum in a vapor cell used in Rydberg atom-based sensors. These surface E-fields can res…
Two-dimensional imaging of electromagnetic fields via light sheet fluorescence imaging with Rydberg atoms
Noah Schlossberger, Tate McDonald, Kevin Su +9
The ability to image electromagnetic fields holds key scientific and industrial applications, including electromagnetic compatibility, diagnostics of high-frequency devices, and ex…
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…
