Orbital Feshbach Resonance in Alkali-Earth Atoms
Orbital Feshbach Resonance in Alkali-Earth Atoms
For a mixture of alkali-earth atomic gas in the long-lived excited state ^{3}P_{0} and the ground state ^{1}S_{0}, in addition to nuclear spin, another "orbital" index is introduced to distinguish these two internal states. In this Letter we propose a mechanism to induce Feshbach resonance between two atoms with different …
