Quasiparticle Excitation Spectrum of an Isolated Vortex in a High–Temperature Superconductor
نویسندگان
چکیده
The quasiparticle energy spectrum of an isolated vortex in a clean layered d-wave superconductor is calculated. The Bogoliubov–de Gennes equations are solved perturbatively, within the model of step-variation of the gap function, adjusting the Caroli, de Gennes and Matricon approach for low-lying excitations in cuprates. A large peak in the density of states in a ”pancake” vortex is found, as a consequence of two-dimensionality and strong coupling. PACS numbers: 74.60.-w, 74.20.Fg

Quasiparticle Spectrum of Vortices in Cuprates
The quasiparticle excitation spectrum of an isolated vortex in a clean layered d-wave superconductor is calculated, using both the Bogoliubov–de Gennes and the quasiclassical Eilenberger equations. Analytical solutions are obtained within the model of step-variation of the gap function, adjusting the Caroli, de Gennes and Matricon approach for low-lying excitations in cuprates. A large peak in ...
متن کاملHot-electron Instability in Superconductors
High flux velocities in a superconductor can distort the quasiparticle distribution function and elevate the electronic temperature. Close to Tc, a non-thermal distribution function shrinks the vortex core producing the well-known Larkin-Ovchinnikov flux instability. In the present work we consider the opposite limit of low temperatures, where electron-electron scattering is more rapid than ele...
متن کاملMixed-state penetration depths in s-wave and d-wave superconductors
We report on a microscopic calculation of the current and magnetic field distribution in the mixed state of model s-wave and d-wave superconductors. For the d-wave case, we find that corrections to London theory are important at fields small compared to Hc2. The field distribution is influenced by both superfluid-velocity dependence and non-locality in the current response function of the mixed...
متن کاملMixed-state quasiparticle spectrum for d-wave superconductors.
Controversy concerning the pairing symmetry of high-Tc materials has motivated an interest in those measureable properties of superconductors for which qualitative differences exist between the s-wave and d-wave cases. We report on a comparison between the microscopic electronic properties of dwave and s-wave superconductors in the mixed state. Our study is based on self-consistent numerical so...
متن کاملWiedemann-Franz violation in the vortex state of a d-wave superconductor
We show that the Wiedemann-Franz law is violated in the vortex state of a d-wave superconductor at zero temperature. We use a semiclassical approach, which includes the Doppler shift on the quasiparticles as well as the Andreev scattering from a random distribution of vortices. We also show that the vertex corrections to the electrical conductivity due to the anisotropy of impurity scattering b...
