d-wave pairing symmetry in cuprate superconductors
Phase-sensitive tests of pairing symmetry have provided strong evidence for predominantly d-wave pairing symmetry in both the holeand electron-doped high-Tc cuprate superconductors. Temperature dependent measurements in YBa2Cu3O7−δ (YBCO) indicate that the d-wave pairing dominates, with little if any imaginary component, at all temperatures from 0.5K through Tc. In this article we review some o...

متن کاملS- and D-wave Pairing in Short Coherence Length Superconductors
Over the past three years or so the evidence has become overwhelming that the cuprate high Tc superconductors have a d-wave pairing state[1]. The measurements of Wollman et al.[2] and of Tsuei et al.[3] are especially convincing since they do not depend on the microscopic physics of the energy gap, but instead depend only on the order parameter phase. Other experiments, such as photoemission[4,...
متن کاملCorrelation between characteristic energies in non–s-wave pairing superconductors
By solution of the Bethe-Goldstone equation for the Cooper pairing problem, an approximate analytic relation is derived between coherence length ξ and the binding energy of the Cooper pair. This relation is then qualitatively confirmed by numerically solving the corresponding self-consistent gap equations, following the crossover from weak to strong coupling, in non–s-wave superconductors. The ...
متن کاملPhase diagram of the pairing symmetry in two-dimensional strong-coupling superconductors
Two-dimensional Eliashberg equations have been solved by use of a mixed interaction with sand d-channels. It is discussed what kind of pairing symmetry of the superconducting state can be realized when the channel mixing parameters and the band-filling are varied. By changing the mixing parameters and varying the chemical potential μ between zeroand half-filling, the pairing symmetry is determi...
