    "abstract": "We study the neutron-proton pairing in nuclear matter as a function of\nisospin asymmetry at finite temperatures and the saturation density using\nrealistic nuclear forces and Brueckner-renormalized single particle spectra.\nOur computation of the thermodynamic quantities shows that while the difference\nof the entropies of the superconducting and normal phases anomalously changes\nits sign as a function of temperature for arbitrary asymmetry, the grand\ncanonical potential does not; the superconducting state is found to be stable\nin the whole temperature-asymmetry plane. The pairing gap completely disappears\nfor density-asymmetries exceeding $\\alpha_c= (n_n-n_p)/n \\simeq 0.11$.",
