Abstract:

In this talk, I will firstly review the recent advance of the degenerate alkaline-earth atoms. Then I show the scheme of orbital Feshbach resonance whichcan be used to tune the interaction strength between alkaline-earth atoms. Since the existence of spin-exchange interaction, alkaline-earth atomic gas becomes the ideal platform to simulation Kondo model in cold atom physics. I will show that we can use confinement induced resonance in mixed dimension to enhance the spin-exchange interaction, which may make the Kondo temperature to be achievable in current experiment.
