Projected sensitivity of a spinor Bose-Einstein condensate comagnetometer to proton monopole-dipole interactions
Wenjing Zhou, Diego Blas, Morgan W. Mitchell
Light spin-zero bosons with scalar and pseudoscalar couplings mediate a parity- and time-reversal-violating monopole-dipole interaction between unpolarized matter and polarized spi…
Systematic errors from scalar slowing-down models in transient SERF magnetometry
Marek Kopciuch, M. Kopciuch, Harini Raghavan +3
Reduced Bloch models of spin-exchange-relaxation-free (SERF) magnetometers commonly describe the coupled electron--nuclear spin dynamics using a single nuclear slowing-down factor.…
Sensitivity Scaling and Limits of Cavity Enhancement in Miniaturized Optically Pumped Magnetometers
Christopher H. Kiehl, María Hernández Ruiz, Cristina Sastre Jachimska +1
The sensitivity of miniaturized optically pumped magnetometers (OPMs) is limited by weak atom-light coupling, which an optical cavity can enhance. In this work, we model the photon…
A single atom emitting resonance fluorescence into a coherent beam, and its use for non-destructive atom thermometry
Tomáš Lamich, Laura Zarraoa, Sondos Elsehimy +2
Using a far-off-resonance optical dipole trap, we place a single neutral Rb atom in a weak, atom-resonant coherent beam, while also strongly illuminating it from an orthogon…
Dynamics of hyperpolarized nuclear spins at Zeeman-insensitive points
James Eills, Anushka Singh, Amir-Mahyar Teimoori +3
Avoided crossing (LAC) transitions are central to spin-based precision measurements since they provide strong observability and field-perturbation insensitivity, but while observed…
Magnetotactic bacterial populations studied with a Pound-Drever-Hall atomic magnetometer
María Hernández Ruiz, Christopher Kiehl, Vito Giovanni Lucivero +1
We demonstrate an optically pumped magnetometer that monitors spin polarization using Pound Drever Hall (PDH) technique. The instrument exhibits a noise floor of 22.2 pT/sqrt(Hz) l…
Functionalized mm-scale vapor cells for alkali-metal spectroscopy and magnetometry
Harini Raghavan, Michael C. D. Tayler, Kostas Mouloudakis +9
We describe micro-fabricated rubidium vapor cells with integrated temperature-control functionality and demonstrate their suitability for use in miniaturized ultra-sensitive magnet…
Laser-written micro-channel atomic magnetometer
Andrea Zanoni, Kostas Mouloudakis, Michael C. D. Tayler +4
We demonstrate a sensitive optically-pumped magnetometer using rubidium vapor and 0.75 amg of nitrogen buffer gas in a sub-mm-width sensing channel excavated by femtosecond laser w…
Quantum jump photodetector for narrowband photon counting with a single atom
Laura Zarraoa, Romain Veyron, Tomas Lamich +2
Using a single neutral 87Rb atom held in an optical trap, and "quantum jump" detection of single-photon-initiated state changes, we demonstrate a single-photon quantum jump photode…
Live magnetic observation of parahydrogen hyperpolarization dynamics
James Eills, Morgan W. Mitchell, Irene Marco Rius +1
Hyperpolarized nuclear spins in molecules exhibit high magnetization that is unachievable by classical polarization techniques, making them widely used as sensors in physics, chemi…
