Query: In-medium bound-state formation and inhomogeneous condensation in Fermi
  gases in a hard-wall box   The formation of bosonic bound states underlies the formation of a superfluid
ground state in the many-body phase diagram of ultracold Fermi gases. We study
bound-state formation in a spin- and mass-imbalanced ultracold Fermi gas
confined in a box with hard-wall boundary conditions. Because of the presence
of finite Fermi spheres, the center-of-mass momentum of the potentially formed
bound states can be finite, depending on the parameters controlling mass and
spin imbalance as well as the coupling strength. We exploit this observation to
estimate the potential location of inhomogeneous phases in the many-body phase
diagram as a function of spin- and mass imbalance as well as the box size. Our
results suggest that a hard-wall box does not alter substantially the many-body
phase diagram calculated in the thermodynamic limit. Therefore, such a box may
serve as an ideal trap potential to bring experiment and theory closely
together and facilitate the search for exotic inhomogeneous ground states.
