Phase Fluctuations in High Temperature Superconductors
Wonkee Kim, Yan Chen, C. S. Ting
Within the phase fluctuation picture for the pseudogap state of a high- superconductor, we incorporate the phase fluctuations generated by the classical XY model with the Bo…
Microwave Conductivity of a High Purity d-wave Superconductor
Wonkee Kim, F. Marsiglio, J. P. Carbotte
The cusp-like behavior of the microwave conductivity observed in clean ortho-II YBCuO at low temperature and low frequency is shown to be related directly to a…
Low Temperature Thermal Conductivity of High Purity YBaCuO in the Vortex State
Wonkee Kim, F. Marsiglio, J. P. Carbotte
The low temperature thermal conductivity of a d-wave superconductor is considered for arbitrary strength of the impurity potential. A random distribution of vortices is included wi…
Wiedemann-Franz violation in the vortex state of a d-wave superconductor
Wonkee Kim, F. Marsiglio, J. P. Carbotte
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 shi…
