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, … Web3 hours ago · Schematic representation of the superconducting diode, where a two-dimensional (2D) S/F structure is placed on the surface of a three-dimensional (3D) topological insulator.
