On Distinguishing d-wave from Highly Anisotropic s-wave Superconductors
Systematic impurity doping in the Cu-O plane of the hole-doped cuprate superconductors may allow one to decide between unconventional (”d-wave”) and anisotropic conventional (”s-wave”) states as possible candidates for the order parameter in these materials. We show that potential scattering of any strength always increases the gap minima of such s-wave states, leading to activated behavior in ...
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 کاملOff-Diagonal Nonmagnetic Disorder in s- and d-Wave Superconductors
The previously developed approach to study off-diagonal disorder has been extended and applied to both sand d-wave superconductors. The derived equations allow the self-consistent solution of the problem. For a special case of negative U centres embedded in non-superconducting host we have calculated their critical concentration for the appearance of superconductivity and found it equal to ≈ 0....
متن کاملTilt Grain - Boundary Effects in S − and D − Wave Superconductors
We calculate the s− and d−wave superconductor order parameter in the vicinity of a tilt grain boundary. We do this self-consistently within the Bogoliubov de Gennes equations, using a realistic microscopic model of the grain boundary. We present the first self-consistent calculations of supercurrent flows in such boundaries, obtaining the current-phase characteristics of grain boundaries in bot...
متن کاملNonlinear magneto-optical response of s- and d-wave superconductors.
The nonlinear magneto-optical response of sand d-wave superconductors is discussed. We carry out the symmetry analysis of the nonlinear magneto-optical susceptibility in the superconducting state. Due to the surface sensitivity of the nonlinear optical response for systems with bulk inversion symmetry , we perform a group theoretical classification of the superconducting order parameter close t...
