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