Mechanism of High Temperature Superconductivity in a striped Hubbard Model
E. Arrigoni, E. Fradkin, S. A. Kivelson
It is shown, using asymptotically exact methods, that the two dimensional repulsive Hubbard model with strongly modulated interactions exhibits ``high temperature superconductivity…
Incipient order in the t-J model at high temperatures
Leonid P. Pryadko, Steven A. Kivelson, Oron Zachar
We analyze the high-temperature behavior of the susceptibilities towards a number of possible ordered states in the t-J-V model using the high-temperature series expansion. From al…
Quasi-1D dynamics and nematic phases in the 2D Emery model
Steven A. Kivelson, Eduardo Fradkin, Theodore Geballe
We consider the Emery model of a Cu-O plane of the high temperature superconductors. We show that in a strong-coupling limit, with strong Coulomb repulsions between electrons on ne…
