Query: Effect of Fermi surface evolution on superconducting gap in
  superconducting topological insulator   We study bulk electronic states of superconducting topological insulator,
which is the promising candidate for topological superconductor. Recent
experiments suggest that the three-dimensional Fermi surface evolves into
two-dimensional one. We show that the superconducting energy gap structure on
the Fermi surface systematically changes with this evolution. It is clarified
that the bulk electronic properties such as spin-lattice relaxation rate and
specific heat depend on the shape of the Fermi surface and the type of the
energy gap function. These results serve as a guide to determine the pairing
symmetry of Cu$_x$Bi$_2$Se$_3$.
