Optical tuning of the scattering length of cold alkaline-earth-metal atoms
Optical tuning of the scattering length of cold alkaline-earth-metal atoms
It is possible to tune the scattering length for the collision of ultracold ground-state alkaline-earth-metal atoms using an optical Feshbach resonance. This is achieved with a laser far detuned from an excited molecular level near the frequency of the atomic intercombination transition. Simple resonant-scattering theory, illustrated by the example of …
