Pairing in low-density Fermi gases. Papenbrock, T. & Bertsch, G. F. Physical Review C - Nuclear Physics, 59(4):2052–2055, 1999. doi abstract bibtex We consider pairing in a dilute system of fermions with a short-range interaction. While the theory is ill-defined for a contact interaction, the BCS equations can be solved in the leading order of low-energy effective field theory. The integrals are evaluated with the dimensional regularization technique, giving analytic formulas relating the pairing gap, the density, and the energy density to the two-particle scattering length. \textcopyright 1999 The American Physical Society.
