How accurately can the Extended Thomas-Fermi method describe the inner crust of a neutron star?

Year: 2020

Type: article

Abstract: We perform a systematic comparison between the results obtained by solving fully self-consistently the Hartree-Fock-Bogoliubov equations, and those obtained using the semi-classical Extended Thomas-Fermi method, for various Wigner-Seitz cells within the inner crust of a neutron star.The lack of pairing correlations in the semi-classical approach leads to a large discrepancy between the two approaches.This discrepancy is well beyond the error of the quantum-mechanical calculation, and is related to spurious shell effects in the neutron gas.
