Description
I discuss the existence of long-lived repulsive as well as
attractive polarons in a strongly interacting Fermi gas. The
energy, lifetime, and quasiparticle residue of the polarons
are calculated, and I show show how they accurately
describe experimental data. Finally, I discuss possible
consequences of these results regarding observing itinerant
ferromagnetism in atomic gases
