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 ...
متن کاملVortex structure in d-wave superconductors.
Vortex structure of pure d x 2 y 2 -wave superconductors is microscopically analyzed in the framework of the quasi-classical Eilenberger equations. Selfconsistent solution for the d-wave pair potential is obtained for the rst time in the case of an isolated vortex. The vortex core structure, i.e., the pair potential, the supercurrent and the magnetic eld, is found to be fourfold symmetric even ...
متن کاملVortex lattice transition in D-wave superconductors
Making use of the extended Ginzburg Landau theory, which includes the fourth order derivative term, we study the vortex state in a magnetic field parallel to the c axis. The vortex core structure is distorted due to this higher order term, which reveals the fourfold symmetry. Further, this distortion gives rise to the core interaction energy, which favors a square lattice tilted by 45 from the ...
متن کاملOn 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 کاملNovel vortex lattice transition in d-wave superconductors
We study the vortex state in a magnetic field parallel to the c axis in the framework of the extended Ginzburg Landau equation. We find the vortex acquires a fourfold modulation proportional to cos(4φ) where φ is the angle r makes with the a-axis. This term gives rise to an attractive interaction between two vortices when they are aligned parallel to (1, 1, 0) or (1,−1, 0). We predict the first...
