Query: Surface Bound States and Spontaneous Current in Cyclic d-Wave
  Superconductors   On the basis of Eilenberger theory, surface bound states and spontaneous
current are studied in cyclic d-wave superconductors as a broken time-reversal
symmetry of superconductivity in cubic lattice symmetry. We discuss how the
spontaneous current and the electronic states depend on the orientation of the
surface relative to the symmetry of superconductivity. The condition for
topological Fermi arcs of zero-energy surface bound states to appear is
identified in the complex pairing function of the cyclic d-wave.
