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…

Detection of photon-level signals embedded in sunlight with an atomic photodetector
Laura Zarraoa, Tomas Lamich, Sondos Elsehimy +2
The detection of few-photon signals in a broadband background is an extreme challenge for photon counting, requiring filtering that accepts a narrow range of optical frequencies wh…
