Resonant Spin Excitation in an Overdoped High Temperature Superconductor

Quasiparticle Excitation Spectrum of an Isolated Vortex in a High–Temperature Superconductor

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...

Strength of the spin-fluctuation-mediated pairing interaction in a high-temperature superconductor

Theories based on the coupling between spin fluctuations and fermionic quasiparticles are among the leading contenders to explain the origin of high-temperature superconductivity, but estimates of the strength of this interaction differ widely1. Here, we analyse the chargeand spin-excitation spectra determined by angle-resolved photoemission and inelastic neutron scattering, respectively, on th...
