Achieving a long lifetime synchronized state in a thermal vapor Rydberg time crystal
William J. Watterson, Dixith Manchaiah, Christopher L. Holloway
Time crystals are a unique and recently discovered state of matter in which time-translational symmetry is spontaneously broken. Although this state has been observed across a vari…
Frequency-Axis Calibration via Autler-Townes Splitting in an Electromagnetically Induced Transparency Feature
Stone B. Oliver, Noah Schlossberger, Tate McDonald +2
Rydberg atom-based electrometry is a pivotal technology that enables radio-frequency (rf) field measurements traceable to the International System of Units. This is typically accom…
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…
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…
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…
Fundamental linewidth limit of electromagnetically induced transparency in a thermal Rydberg ladder
Noah Schlossberger, Nikunjkumar Prajapati, Alexandra B. Artusio-Glimpse +2
Spectroscopy of Rydberg states has become a popular platform for quantum sensing, with the most common readout scheme being two-photon electromagnetically induced transparency (EIT…
Simultaneous Detection, Demodulation, and Angle-of-Arrival Determination of Communication Signals Using a Dual Ladder Rydberg Receiver
Stone B. Oliver, Samuel Berweger, Eugeniy E. Mikhailov +4
In a typical Rydberg mixer, modulated communication signals are detected using a radio frequency (RF) heterodyne technique. The mixer outputs an intermediate frequency (IF), which…
Development of a Quantum Blackbody Thermometer toward Primary On-orbit Thermometry
Peter J. Beierle, Denis Tremblay, Noah Schlossberger +3
We present a roadmap to a deployable, intrinsically calibrated thermometer with long-term accuracy of 30 mK, exceeding existing on-orbit resistance-based thermometers. Our quantum…
