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…

Precise, super-resolving intensity measurement by quantum jump spectroscopy of a single neutral atom
Lorena C. Bianchet, Natalia Alves, Laura Zarraoa +3
We present precise, sub-wavelength optical intensity measurement using a single trapped Rb atom as a sensor. The intensity is measured by the scalar ac Stark shift it produc…
