Chiral p wave
WebThis has important consequences for possible chiral superconducting states: While square-lattice symmetry as found in Sr 2 RuO 4 generically triggers a chiral p-wave triplet order parameter due to the degeneracy of p x - and p y-wave at the instability level, hexagonal symmetry implies degeneracy in the d x 2 − y 2 - and d x y-wave channel, too. Webbend up for a large k. Therefore, a chiral (f þif)-wave superconducting pairing is obtained when only the lowest HH band is occupied with holes. A chiral (f þif)-wave superconductor should have a full pairing gap in the 2D bulk, and C ¼ 3 gapless chiral Majorana fermions at the edge [16], where C ¼ 1 2 P E n<0 R d2k n z is the first Chern ...
