Feedback effects and the self-consistent Thouless criterion of the attractive Hubbard model
K. S. D. Beach, R. J. Gooding, F. Marsiglio
We propose a fully microscopic theory of the anomalous normal state of the attractive Hubbard model in the low-density limit that accounts for propagator renormalization. Our analy…
Anisotropic penetration depth and optical sum rule violation in La_(2-x)Sr_xCuO_4
F. Marsiglio, J. E. Hirsch
We calculate the doping dependence of the penetration depths and optical sum rule violation in La_(2-x)Sr_xCuO_4 within the model of hole superconductivity. In the clean limit the…
Optical sum rule violation, superfluid weight and condensation energy in the cuprates
J. E. Hirsch, F. Marsiglio
The model of hole superconductivity predicts that the superfluid weight in the zero-frequency -function in the optical conductivity has an anomalous contribution from high frequ…
The Anderson prescription for surfaces and impurities
K. Tanaka, F. Marsiglio
We test the Anderson prescription [1], a BCS formalism for describing superconductivity in inhomogeneous systems, and compare results with those obtained from the Bogoliubov-de Gen…
Anderson's "Theorem" and Bogoliubov-de Gennes Equations for Surfaces and Impurities
K. Tanaka, F. Marsiglio
In order to incorporate spatial inhomogeneity due to nonmagnetic impurities, Anderson [1] proposed a BCS-type theory in which single-particle states in such an inhomogeneous system…
