Query: Rotational Isotropy Breaking as Proof for Spin-polarized Cooper Pairs in
  the Topological Superconductor CuxBi2Se3   In a promising candidate of topological superconductors, CuxBi2Se3, we
propose a way to exclusively determine the pairing symmetry. The proposal
suggests that the angle dependence of the thermal conductivity in the basal
ab-plane shows a distinct strong anisotropy only when the pairing symmetry is
an odd-parity spin-polarized triplet below the superconducting transition
temperature (Tc). Such striking isotropy breaking below Tc is explicitly
involved in Dirac formalism for superconductors, in which the spin-orbit
coupling is essential. We classify possible gap functions based on the Dirac
formalism and clarify an origin of the isotropy breaking.
