Motivated by recent cold atom experiments exploring the phase structure of Bose-Fermi mixtures, we propose novel emergent bound states. Cold atoms embedded in a degenerate Fermi system interact via a fermionic analog of the Casimir force, which is an attraction of a −1/r form at distances shorter than the Fermi wavelength.
