WebMay 31, 2014 · Chiral d-wave superconductivity in doped graphene. A highly unconventional superconducting state with a spin-singlet -wave, or chiral d-wave, symmetry has recently been proposed to emerge from electron-electron interactions in doped graphene. Especially graphene doped to the van Hove singularity at 1/4 doping, … WebThe appearance of chiral d-wave superconductivity is intimately linked to the hexagonal crystal lattice and we also offer a brief overview of other materials which have also been …
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. WebApr 20, 2024 · Employing the recently proposed TRILEX method, we find an unconventional superconducting phase of chiral d-wave symmetry in hole-doped systems. Contrary to usual scenarios where charge and spin fluctuations are seen to compete, here the superconductivity is driven simultaneously by both charge and spin fluctuations and …
WebNov 24, 2016 · There are rather few materials showing signature of spin-triplet pairing superconductivity. One notable example is Sr 2 RuO 4, for which the superconducting order parameter (OP) was suggested to have chiral p-wave symmetry [1, 2].Mixed spin-singlet and spin-triplet pairing was observed in non-centrosymmetric heavy fermion …
