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. WebAug 7, 2024 · Spin-triplet superconductivity is a condensate of electron pairs with spin-1 and an odd-parity wavefunction. A particularly interesting manifestation of triplet pairing is a chiral p-wave state which is topologically non-trivial and a natural platform for realizing Majorana edge modes. Triplet pairing is however rare in solid state systems and so far, …
