Nesting Mechanism for d-symmetry Superconductors
arXiv:cond-mat/9403013 · doi:10.1103/PhysRevB.51.3797
Abstract
A nested Fermi surface with nearly parallel orbit segments is found to yield a singlet d-wave superconducting state at high temperatures for a restricted range of the on-site Coulomb repulsion that avoids the competing spin density wave instability. The computed superconducting transition temperature drops dramatically as the nesting vector is decreased, in accord with recent photo-emission data on the Bi2212 and Bi2201 cuprates.
