| Abstract: |
Despite the absence of viscous drag, the neutron superfluid permeating the inner crust of a neutron star can still be
strongly coupled to nuclei due to non-dissipative entrainment effects. Neutron superfluidity and entrainment have been
systematically studied in all regions of the inner crust of a cold non-accreting neutron star in the framework of the
band theory of solids. It is shown that in the intermediate layers of the inner crust a large fraction of “free” neutrons
are actually entrained by the crust. The results suggest that a revision of the interpretation of many observable astrophysical
phenomena might be necessary. |
