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…
Cavity-enhanced detection of spin polarization in a microfabricated atomic vapor cell
María Hernández Ruiz, Yintao Ma, Hana Medhat +3
We demonstrate continuous Pound-Drever-Hall (PDH) nondestructive monitoring of the electron spin polarization of an atomic vapor in a microfabricated vapor cell within an optical r…
Effects of spin-exchange collisions on the fluctuation spectra of hot alkali-metal vapors
K. Mouloudakis, G. Vasilakis, V. G. Lucivero +3
We present a first-principles analysis of the noise spectra of alkali-metal-metal vapors in and out of the spin-exchange-relaxation-free (SERF) regime, and we predict non-intuitive…
Miniature biplanar coils for alkali-metal-vapor magnetometry
Michael C. D. Tayler, Kostas Mouloudakis, Rasmus Zetter +5
Atomic spin sensors offer precision measurements using compact, microfabricated packages, placing them in a competitive position for both market and research applications. Performa…
Cavity-enhanced polarization rotation measurements for low-disturbance probing of atoms
Chiara Mazzinghi, Daniel Benedicto Orenes, Pau Gomez +4
We propose and demonstrate cavity-enhanced polarization-rotation measurement as a means to detect magnetic effects in transparent media with greater sensitivity at equal optical di…
Heading errors in all-optical alkali-vapor magnetometers in geomagnetic fields
W. Lee, V. G. Lucivero, M. V. Romalis +3
Alkali-metal atomic magnetometers suffer from heading errors in geomagnetic fields as the measured magnetic field depends on the orientation of the sensor with respect to the field…
Femtotesla direct magnetic gradiometer using a single multipass cell
V. G. Lucivero, W. Lee, N. Dural +1
We describe a direct gradiometer using optical pumping with opposite circular polarization in two Rb atomic ensembles within a single multipass cell. A far-detuned probe las…
