| Abstract: | I will present controlled numerical results for the ground state spectral function of the resonant Fermi polaron in three dimensions and discuss the existence of a "dark continuum" -- a region of anomalously low spectral weight between the narrow polaron peak and the broad spectral continuum maximum at positive energy. Surprisingly, the dark continuum develops when the s-wave scattering length is of the order of the inverse Fermi wavevector, i.e. in the absence of a small interaction-related parameter. |
