Mixed state Hall effect in the multiphase superconductors
Hall effect below Tc in multiphase superconductors has been studied on Bi-based superconductors. Samples with different relative content of 2212 and 2223 phase have been prepared. The phase content has been verified by X-ray diffraction. Results show that while resistance and ac susceptibility is almost insensitive to the content of 2212 phase, the qualitative behavior of the Hall resistance is...
متن کاملQuantized thermal Hall effect in the mixed state of d-wave superconductors.
We consider quasiparticles of a clean d-wave superconductor in the vortex lattice state. For vortex lattices that are inversion symmetric, the quasiparticle bands are found to have a Dirac cone dispersion at zero energy, within the linearized approximation. Upon going beyond the linearized approximation by including the effect of the smaller curvature terms, the Dirac cone dispersions acquire a...
متن کاملDirac nodes and quantized thermal Hall effect in the mixed state of d-wave superconductors
We consider the vortex state of d-wave superconductors in the clean limit. Within the linearized approximation the quasiparticle bands obtained are found to posess Dirac cone dispersions ~band touchings! at special points in the Brillouin zone. They are protected by a symmetry of the linearized Hamiltonian that we call TDirac . Moreover, for vortex lattices that possess inversion symmetry, it i...
متن کاملWeak-field thermal hall conductivity in the mixed state of d-wave superconductors.
Thermal transport in the mixed state of a d-wave superconductor is considered within the weak-field regime. We express the thermal conductivity, kappa(xx), and the thermal Hall conductivity, kappa(xy), in terms of the cross section for quasiparticle scattering from a single vortex. Solving for the cross section (neglecting the Berry phase contribution and the anisotropy of the gap nodes), we ob...
متن کاملSpin quantum Hall effect in unconventional superconductors
We study the properties of the ‘‘spin quantum Hall fluid’’—a spin phase with quantized spin Hall conductance that is potentially realizable in superconducting systems with unconventional pairing symmetry. A simple realization is provided by a dx22y21idxy superconductor which we argue has a dimensionless spin Hall conductance equal to 2. A theory of the edge states of the dx22y21idxy superconduc...
