Profiling a Rydberg-Atom Electric Field Sensor for Off-Resonant Detection of Sub-100 MHz RF Signals
Michael A. Viray, Abby Halasi-Kun, Baran N. Kayim +3
We present a Rydberg-Atom electric field sensor optimized to detect signals at sub-100 MHz carrier frequencies. The sensing setup employs a sapphire vapor cell that allows for dete…
Calibration of electric fields in low-frequency off-resonant Rydberg receivers
Baran Kayim, Michael A. Viray, David S. La Mantia +5
We present results on Rydberg atom-based electric field sensing in the range of 1 kHz - 300 MHz, using a three-photon Rydberg excitation scheme and a transverse electromagnetic (TE…
Rydberg state engineering: A comparison of tuning schemes for continuous frequency sensing
Samuel Berweger, Nikunjkumar Prajapati, Alexandra B. Artusio-Glimpse +11
On-resonance Rydberg atom-based radio-frequency (RF) electric field sensing methods remain limited by the narrow frequency signal detection bands available by resonant transitions.…
Modeling Line Broadening and Distortion Due to Spatially Non-Uniform Fields in Rydberg Electrometry
Andrew P. Rotunno, Amy K. Robinson, Samuel Berweger +4
We present a model for calculating broadened Autler-Townes spectra when probing ac electric field magnitudes by use of Rydberg atom electromagnetically-induced transparency. This m…
Very-high- and ultrahigh- frequency electric field detection using high angular momentum Rydberg states
Roger C. Brown, Baran Kayim, Michael A. Viray +3
We demonstrate resonant detection of rf electric fields from 240 MHz to 900 MHz (very-high-frequency (VHF) to ultra-high-frequency (UHF)) using electromagnetically induced transpar…
Measurement of DC and AC electric fields inside an atomic vapor cell with wall-integrated electrodes
Lu Ma, Michael A. Viray, David A. Anderson +1
We present and characterize an atomic vapor cell with silicon ring electrodes directly embedded between borosilicate glass tubes. The cell is assembled with an anodic bonding metho…
Photoionization of and Rydberg atoms of Rb and Cs from the near-infrared to the ultraviolet spectral region
Michael A. Viray, Eric Paradis, Georg Raithel
We present calculations of the photoionization (PI) cross sections of rubidium and cesium Rydberg atoms for light with wavelengths ranging from the infrared to the ultraviolet, usi…
Long-range Rydberg-atom-ion molecules of Rb and Cs
A. Duspayev, X. Han, M. A. Viray +3
We propose a novel type of Rydberg dimer, consisting of a Rydberg-state atom bound to a distant positive ion. The molecule is formed through long-range electric-multipole interacti…
A magneto-optical trap with millimeter ball lenses
Cainan S. Nichols, Leo M. Nofs, Michael A. Viray +3
We present a magneto-optical trap (MOT) design based on millimeter ball lenses, contained within a metal cube of 0.75 side length. We present evidence of trapping…
Coulomb Expansion of Cold Non-Neutral Rubidium Plasma
Michael A. Viray, Stephanie A. Miller, Georg Raithel
We study the expansion of a cold, non-neutral ion plasma into the vacuum. The plasma is made from cold rubidium atoms in a magneto-optical trap (MOT) and is formed via ultraviolet…
Expansion Dynamics of Cold Non-Neutral Plasma
Michael A. Viray, Stephanie A. Miller, Georg Raithel
We study the expansion of a strongly coupled, non-neutral, and cylindrically arranged ion plasma into the vacuum. The plasma is made from cold rubidium atoms in a magneto-optical t…
