Critical Temperature for α-Condensation in Asymmetric Nuclear Matter: The Astrophysical Context

Abstract : The critical temperature for α-particle condensation in nuclear matter with Fermi surface imbalance between protons and neutrons is determined. The in-medium four-body Schrödinger equation, generalizing the Thouless criterion of the BCS transition, is applied using a Hartree-Fock wave function for the quartet projected onto zero total momentum in matter with different chemical potentials for protons and neutrons.
