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 ${}^{87}$Rb atom in a weak, atom-resonant coherent beam, while also strongly illuminating it from an orthogon…
