Multicomponent Fermi systems at low densities
C. J. Pethick, A. Schwenk
We calculate, to second order in the scattering length between two fermions, the Landau quasiparticle interaction for a low-density mixture of two fermion species with unequal dens…

Neutron star matter as a dilute solution of protons in neutrons
J. Keller, K. Hebeler, C. J. Pethick +1
Neutron stars contain neutron-rich matter with around 5% protons at nuclear saturation density. In this Letter, we consider equilibrium between bulk phases of matter based on asymm…
