A He-Ne Ramsey Comagnetometer with sub-nHz frequency resolution
Shaobo Zhang, Jingyao Wang, George Sun +2
Nuclear spin comagnetometers offer exceptional precision in measurements of spin energy levels and exhibit long-term stability, making them powerful tools for probing spin-dependen…
Pulsed Dual-axis Alkali-metal-noble-gas Comagnetometer
Jingyao Wang, Junyi Lee, Hudson Loughlin +2
Alkali-metal-noble-gas comagnetometers are precision probes well-suited for tests of fundamental physics and inertial rotation sensing, combining high sensitivity of the spin-excha…
Long spin-1/2 noble gas coherence times in mm-sized anodically bonded batch-fabricated He-Xe-Rb cells
M. E. Limes, N. Dural, M. V. Romalis +4
As the only stable spin-1/2 noble gas isotopes, He and Xe are promising systems for inertial rotation sensing and searches for exotic spin couplings. Spin-1/2 noble g…
Vapor cell Rydberg atom electrometry with time-separated fields
Michael V. Romalis, Joe Wiedemann, Shaobo Zhang +1
Rydberg atoms have large transition electric dipole moments and high sensitivity to electric fields. We describe a new method for microwave field sensing in a vapor cell consisting…
Large-scale, Multi-pass, Two-chamber RF Atomic Magnetometer
D. J. Heilman, K. L. Sauer, D. W. Prescott +4
We describe one of the largest radio-frequency RF atomic magnetometers presently operating. A total atomic volume of 128 , with correspondingly large number of $^{87…
Femtotesla nearly quantum-noise-limited pulsed gradiometer at Earth-scale fields
V. G. Lucivero, W. Lee, M. V. Romalis +3
We describe a finite fields magnetic gradiometer using an intense pulsed laser to polarize a Rb atomic ensemble and a compact VCSEL probe laser to detect paramagnetic Farada…
