Vortices in neutron 3P2 superfluids in neutron stars

量子物理学・ナノサイエンス第432回セミナー

概要

The interior of a neutron star is expected to be occupied by neutron superfluids. While the outer region should be filled by¹S₀ superfluids consisting of a conventional singlet pairs of neutrons, the inner core may be ³P₂ superfluids consisting of a condensate of spin-triplet p-wave Cooper pairs of neutrons with total angular momentum J=2. This has rich topological structures in both momentum and real spaces: it is a topological superfluid and admits various topological defects such as half-quantum non-Abelian vortices, domain walls, surface topological defects, boojums, and so on. I will give a review of the current status of ³P₂ superfluids with a particular attention to vortices and possible applications to pulsar glitches.
