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…
Understanding the puzzle of angular momentum conservation in beta decay and related processes
Gordon Baym, Jen-Chieh Peng, C. J. Pethick
We ask the question of how angular momentum is conserved in electroweak interaction processes. To introduce the problem with a minimum of mathematics, we first raise the same issue…
Superfluid density in disordered pasta phases in neutron star crusts
Zhao-Wen Zhang, C. J. Pethick
We calculate the superfluid density of nucleons in disordered pasta phases in the inner crust of neutron stars using an effective medium approach which parallels that previously us…
Proton superconductivity in pasta phases in neutron star crusts
Zhao-Wen Zhang, C. J. Pethick
In the so-called pasta phases predicted to occur in neutron star crusts, protons are able to move easily over large distances because the nuclear matter regions are extended in spa…
Equation of state constraints from nuclear physics, neutron star masses, and future moment of inertia measurements
S. K. Greif, K. Hebeler, J. M. Lattimer +2
We explore constraints on the equation of state (EOS) of neutron-rich matter based on microscopic calculations up to nuclear densities and observations of neutron stars. In a previ…
Elastic properties of phases with nonspherical nuclei in dense matter
C. J. Pethick, Zhaowen Zhang, D. N. Kobyakov
We consider the elastic constants of phases with nonspherical nuclei, so-called pasta phases, predicted to occur in the inner crust of a neutron star. First, we treat perfectly ord…
