Quantum calculation of vortices in the inner crust of neutron stars / P. Avogadro, F. Barranco, R. A. Broglia, E. Vigezzi. - In: PHYSICAL REVIEW. C, NUCLEAR PHYSICS. - ISSN 0556-2813. - 75:1(2007), pp. 012805.012805.1-012805.012805.5.
Abstract:
The self-consistent mean-field quantum mechanical solution of a vortex and a nucleus immersed in a sea of free
neutrons, a scenario representative of the inner crust of neutron stars, is presented for the first time. Because of
quantal size effects the phase space for vortices inside the nucleus is essentially zero, so that the vortex core opens
up and surrounds the nucleus. As a consequence, pinned configurations (in which a vortex becomes anchored to
the nucleus) are favored at low and high densities in the inner crust. This result is qualitatively different from that
obtained in all previous models, which predict pinning at intermediate densities.
