Quasiparticle interaction in neutron matter for application in neutron stars

A model for the quasiparticle interaction in neutron matter is presented which includes, both, particle-particle (pp) and particle-hole (ph) correlations. The pp correlations are treated in a semi-empirical way, while ph correlations are incorporated by solving coupled two-body equations for the ph interaction and the scattering amplitude on the Fermi sphere. Antisymmetry is kept at all stages and hence the forward scattering sum rules for the scattering amplitude are obeyed. Results for Landau parameters and transport coefficients in a density regime representing the crust of a neutron star are presented. The 1S0 gap parameter for neutron superfluidity is estimated and we comment briefly on neutron star implications. ((orig.))
