WebAug 14, 2024 · We study a tight-binding model on the honeycomb lattice of chiral d-wave superconductivity that breaks time-reversal symmetry. Because of its nontrivial sublattice structure, we show that it is possible to construct a gauge-invariant time-reversal-odd bilinear of the pairing potential. The existence of this bilinear reflects the sublattice ... Webxy-wave, or chiral d-wave symmetry has recently been suggested to emerge from electron–electron interactions in doped graphene. It has been argued that graphene doped to the van Hove singularity at 1/4 doping, where the density of states diverge, is particularly likely to be a chiral d-wave superconductor. In this review we summarize the ...
WebDec 15, 2024 · Chiral -wave superconductivity has been proposed in a number of different materials, but characteristic experimental fingerprints have been largely lacking.

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. WebFor chiral d-wave pairing the zeroing angle is β ¼ π=4 etc. The vanishing of the Josephson tunneling current at a specific zeroing angle is a clear signature for chiral superconductivity and allows for unambiguous deter-mination of the pairing channel.
