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…
Continuous radio frequency electric-field detection through adjacent Rydberg resonance tuning
Matthew T. Simons, Alexandra B. Artusio-Glimpse, Christopher L. Holloway +5
We demonstrate the use of multiple atomic-level Rydberg-atom schemes for continuous frequency detection of radio frequency (RF) fields. Resonant detection of RF fields by electroma…
An all-optical intrinsic atomic gradiometer with sub-20 fT/cm/ sensitivity in a 22 T earth-scale magnetic field
A. R. Perry, M. D. Bulatowicz, M. Larsen +2
In this work we demonstrate a high sensitivity atomic gradiometer capable of operation in earth-field level environments. We apply a light-pulse sequence at four times the Larmor f…
Nonlinear looped band structure of Bose-Einstein condensates in an optical lattice
Silvio B. Koller, Elizabeth A. Goldschmidt, Roger C. Brown +4
We study experimentally the stability of excited, interacting states of bosons in a double-well optical lattice in regimes where the nonlinear interactions are expected to induce "…
Magic wavelengths for the transition in rubidium
E. A. Goldschmidt, D. G. Norris, S. B. Koller +5
Magic wavelengths, for which there is no differential ac Stark shift for the ground and excited state of the atom, allow trapping of excited Rydberg atoms without broadening the op…
Pneumatically actuated and kinematically positioned optical mounts compatible with laser-cooling experiments
R. C. Brown, S. Olmschenk, S. Wu +3
We present two complementary designs of pneumatically actuated and kinematically positioned optics mounts: one designed for vertical mounting and translation, the other designed fo…
2D Superexchange mediated magnetization dynamics in an optical lattice
R. C. Brown, R. Wyllie, S. B. Koller +3
The competition of magnetic exchange interactions and tunneling underlies many complex quantum phenomena observed in real materials. We study non-equilibrium magnetization dynamics…
Suppression of Spin-Exchange Relaxation Using Pulsed Parametric Resonance
A. Korver, R. Wyllie, B. Lancor +1
We demonstrate that spin-exchange dephasing of Larmor precession at near-earth-scale fields is effectively eliminated by dressing the alkali-metal atom spins in a sequence of AC-co…
Diffusive Suppression of AC-Stark Shifts in Atomic Magnetometers
I. A. Sulai, R. Wyllie, M. Kauer +3
In atomic magnetometers, the vector AC-Stark shift associated with circularly polarized light generates spatially varying effective magnetic fields which limit the magnetometer res…
Optical Magnetometer Array for Fetal Magnetocardiography
Robert Wyllie, Matthew Kauer, Ronald T. Wakai +1
We describe an array of spin-exchange relaxation free optical magnetometers designed for detection of fetal magnetocardiography (fMCG) signals. The individual magnetometers are con…
Magnetocardiography with a modular spin-exchange relaxation free atomic magnetometer array
R Wyllie, M Kauer, G Smetana +2
We present a portable four-channel atomic magnetometer array operating in the spin exchange relaxation-free regime. The magnetometer array has several design features intended to m…
Circular Dichroism of RbHe and RbN Molecules
B. Lancor, E. Babcock, R. Wyllie +1
We present measurements of the circular dichroism of optically pumped Rb vapor near the D1 resonance line. Collisions with the buffer gases He and N reduce the transparency…
Breakdown of Angular Momentum Selection Rules in High Pressure Optical Pumping Experiments
B. Lancor, E. Babcock, R. Wyllie +1
We present measurements, using two complementary methods, of the breakdown of atomic angular momentum selection rules in He-broadened Rb vapor. Atomic dark states are rendered weak…
