The Attractive Hubbard Model in 2D: Is it capable of describing a pseudogap and preformed pairs?
M. Letz
Deviations from Fermi liquid behavior are well documented in the normal state of the cuprate superconductors, and some of these differences seem to be related to pre-transitional f…
Spectral Properties of the Attractive Hubbard Model
M. Letz, R. J. Gooding
Deviations from Fermi liquid behavior are well documented in the normal state of the cuprate superconductors, and some of these differences are possibly related to pre-formed pairs…
Quasiparticle lifetime behaviour in a simplified self-consistent T-matrix treatment of the attractive Hubbard model in 2D
M. Letz, R. J. Gooding
The attractive Hubbard model on a 2-D square lattice is studied at low electronic densities using the ladder approximation for the pair susceptibility. This model includes (i) the…
A self-consistent, conserving theory of the attractive Hubbard model in two dimensions
M. Letz, R. J. Gooding
We have investigated the attractive Hubbard model in the low density limit for the 2D square lattice using the ladder approximation for the vertex function in a self-consistent, co…
