Observation of Coherent Multiorbital Polarons in a Two-Dimensional Fermi Gas
We report on the experimental observation of multiorbital polarons in a two-dimensional Fermi gas of $^{173}\mathrm{Yb}$ atoms formed by mobile impurities in the metastable $^{3}{P}_{0}$ orbital and a Fermi sea in the ground-state $^{1}{S}_{0}$ orbital. We spectroscopically probe the energies of attractive and repulsive polarons close to an orbital Feshbach …
