Role of Van Hove Singularities and Momentum Space Structure in High-Temperature Superconductivity
R. J. Radtke, K. Levin, H. -B. Schuttler +1
There is a great deal of interest in attributing the high critical temperatures of the cuprates to either the proximity of the Fermi level to a van Hove singularity or to structure…

Predictions for Impurity-Induced Tc Suppression in the High-Temperature Superconductors
R. J. Radtke, K. Levin, H. -B. Schuttler +1
We address the question of whether anisotropic superconductivity is compatible with the evidently weak sensitivity of the critical temperature Tc to sample quality in the high-Tc c…
