Landau parameters of nuclear matter in the spin and spin-isospin channels

Abstract

The equation of state of spin and isospin polarized nuclear matter is determined in the framework of the Brueckner theory including three-body forces. The Landau parameters in the spin and spin-isospin sectors are derived as a function of the baryonic density. The results are compared with the Gamow-Teller collective modes. The relevance of $G_0$ and $G_0^{\prime }$ for neutron stars is shortly discussed, including the magnetic susceptibility and the neutron star cooling.
