Orbital ordering of ultracold alkaline-earth atoms in optical lattices
Orbital ordering of ultracold alkaline-earth atoms in optical lattices
We report on a dynamical mean-field theoretical analysis of emerging low-temperature phases in multicomponent gases of fermionic alkaline-earth(-like) atoms in state-dependent optical lattices. Using the example of $^{173}$Yb atoms, we show that a two-orbital mixture with two nuclear spin components is a promising candidate for studies of not only magnetic …
