We report on the first direct observation of fast spin-exchange coherent oscillations between different long-lived electronic orbitals of ultracold 173 Yb fermions. We measure, in a model-independent way, the strength of the exchange interaction driving this coherent process. This observation allows us to retrieve important information on the interorbital collisional properties of 173 Yb atoms and paves the way to novel quantum simulations of paradigmatic models of two-orbital quantum magnetism.

Abstract

We report on the first direct observation of fast spin-exchange coherent oscillations between different long-lived electronic orbitals of ultracold 173 Yb fermions. We measure, in a model-independent way, the strength of the exchange interaction driving this coherent process. This observation allows us to retrieve important information on the interorbital collisional properties of 173 Yb atoms and paves the way to novel quantum simulations of paradigmatic models of two-orbital quantum magnetism.
