Localized Magnetic Moments with Tunable Spin Exchange in a Gas of Ultracold Fermions
Localized Magnetic Moments with Tunable Spin Exchange in a Gas of Ultracold Fermions
We report on the experimental realization of a state-dependent lattice for a two-orbital fermionic quantum gas with strong interorbital spin exchange. In our state-dependent lattice, the ground and metastable excited electronic states of $^{173}\mathrm{Yb}$ take the roles of itinerant and localized magnetic moments, respectively. Repulsive on-site interactions in conjunction with …
