We report on the first direct observation of fast spin-exchange coherent oscillations between different long-lived electronic orbitals of ultracold Yb-173 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 Yb-173 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 Yb-173 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 Yb-173 atoms and paves the way to novel quantum simulations of paradigmatic models of two-orbital quantum magnetism.File in questo prodotto:
