We present a full microscopic many-body calculation of a recently-proposednonlinear two-dimensional spectroscopy for Fermi polarons, and show that thequantum coherence between the attractive and repulsive polarons, which hasnever been experimentally examined, can be unambiguously revealed via quantumbeats at the two off-diagonal crosspeaks in the two-dimensional spectrum. Wepredict that particle-hole excitations make the two crosspeaks asymmetric andlead to an additional side peak near the diagonal repulsive polaron peak. Oursimulated spectra can be readily examined in future cold-atom experiments,where the two-dimensional spectroscopy is to be implemented by using a Ramseyinterference sequence of rf pulses in the time domain. Our results also providea first-principle understanding of the recent two-dimensional coherentspectroscopy of interacting excitons and trions in doped monolayer transitionmetal dichalcogenides.
