NSR strong-coupling corrections δΩNSR to the thermodynamic potential Ω in asymmetric nuclear matter at nonzero temperatures. The solid and dashed lines denote the nucleon Green’s function Gi and the bare nucleon-nucleon interaction Vα(k, k′), respectively. k, k′, and k″ are relative momenta of nucleons and q is the center-of-mass momentum of each pair.
