  In disordered vortices in p-wave superconductors the two new random-matrix
ensembles may be realized: B and DIII-odd (of so(2N+1) and so(4N+2)/u(2N+1)
matrices respectively). We predict these ensembles from an explicit analysis of
the symmetries of Bogoliubov-deGennes equations in three examples of vortices
with different p-wave order parameters. A characteristic feature of the novel
symmetry classes is a quasiparticle level at zero energy. Class B is realized
when the time-reversal symmetry is broken, and class DIII-odd when the
time-reversal symmetry is preserved. We also suggest that the main contribution
to disordering the vortex spectrum comes from the distortion of the order
parameter around impurities.
