Edge Ferromagnetism from Majorana Flat Bands: Application to Split Tunneling-Conductance Peaks in High-T[subscript c] Cuprate Superconductors
In mean-field descriptions of nodal d-wave superconductors, generic edges exhibit dispersionless Majorana fermion bands at zero energy. These states give rise to an extensive ground-state degeneracy, and are protected by time-reversal symmetry. We argue that the infinite density of states of these f...
