A single atom emitting resonance fluorescence into a coherent beam, and its use for non-destructive atom thermometry
Tomáš Lamich, TomᚠLamich, Laura Zarraoa +3
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…

Magnetotactic bacterial populations studied with a Pound-Drever-Hall atomic magnetometer
MarÃa 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…
