Chiral d wave superconductivity
WebNov 19, 2013 · We investigate this possibility via functional renormalization group and find a chiral -wave order parameter favored by the multiband fermiology and hexagonal symmetry of SrPtAs. This -wave state exhibits significant gap anisotropies as well as gap differences on the different bands, but only has point nodes on one of the bands at the Brillouin ... WebWe investigate the combined effect of Hund's and spin-orbit (SO) coupling on superconductivity in multi-orbital systems. Hund's interaction leads to orbital-singlet spin-triplet superconductivity, where the Cooper pair wave function is antisymmetric under the exchange of two orbitals. We identify three d-vectors describing even-parity orbital …

WebApr 7, 2014 · Near this doping level, superconductivity is a universal phenomenon, arising from any choice of bare repulsive interactions. The strongest pairing instability is into a chiral d -wave state ( d+id ). At a truly weak coupling, the strongest competitor is a spin-density-wave instability, however, d -wave superconductivity still wins.

WebJun 23, 2024 · Surprisingly, the chiral d-wave superconductivity is strongly suppressed by a weak nearest-neighbor exchange coupling in our calculations. We argue that this suppression might be one of the reasons why the chiral superconductivity proposed for doped graphene has not yet been observed experimentally.
Webxy-wave, or chiral d-wave symmetry has recently been suggested to emerge from electron–electron interactions in doped graphene.
