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 ...

Quasi-Particle Spectrum around a Single Vortex in Superconductors s-Wave Case

Making use of the Bogoliubov-de Gennes equation, we study the quasi-particle spectrum and the vortex core structure of a single vortex in quasi 2D s-wave superconductors for small pF ξ0, where pF is the Fermi momentum and ξ0 = vF /∆0 is the coherence length (h̄ = 1). During our numerical calculation the particle number is conserved for each pF ξ0. In particular, we find that there are only 1 or ...

Superconducting properties of the s ±-wave state: Fe-based superconductors.

Although the pairing mechanism of Fe-based superconductors (FeSCs) has not yet been settled with consensus with regard to the pairing symmetry and the superconducting (SC) gap function, the vast majority of experiments support the existence of spin-singlet sign-changing s-wave SC gaps on multi-bands ([Formula: see text]-wave state). This multi-band [Formula: see text]-wave state is a very uniqu...

Nonlinear 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...

Quantum corrals, eigenmodes, and quantum mirages in s-wave superconductors.

We study the electronic structure of magnetic and nonmagnetic quantum corrals embedded in two-dimensional s-wave superconductors. We demonstrate that a quantum mirage of an impurity bound state is projected from the occupied into the empty focus of a nonmagnetic quantum corral via the excitation of the corral's eigenmodes. We show that quantum corrals provide a new tool for manipulating the int...
