Description
I will report on new directions for quantum simulation with ultracold Fermi gases of two-electron $^{173}$Yb atoms. Manipulation of their electronic state on the ultranarrow clock transition allowed us to engineer a new kind of magnetic interaction [1] and to produce strongly interacting Fermi gases with orbital degree of freedom at a newly discovered orbital Feshbach resonance [2]. By manipulating their nuclear spin we realized systems of fermions with tunable SU(N) symmetry [3] and demonstrated a new concept for atomic physics experiments based on the realization of a “synthetic dimension”, that we have used to produce gauge fields and directly observe the propagation of chiral edge states in a quantum Hall system [4].
