Query: Vortex lattice in rotating neutron spin-triplet superfluid   In the Ginzburg-Landau limit, a possible texture without singular cores in a
rotating neutron spin-triplet superfluid is studied. It is constructed the
lattice of non-singular vortices with a vorticity diffusely distributed over
the entire unit cell. The upper limit of the free energy associated with this
structure is estimated, and the result shows that non-singular vortices are
more preferable in the core of rotating neutron stars than ordinary linear
singular vortices. The order parameter of the studied neutron system belongs to
the unitary class. This implies that the superfluid under consideration does
not have spin polarization and the core-less $^{3}$P$_{2}$ vortices do not have
magnetization, which makes electron scattering by vortices ineffective. For the
same reason, pinning with flux tubes is also suppressed. This can affect the
hydrodynamics of superfluid neutron stars.
