d-wave superconductivity in a generalized Hubbard model

Liliana Arrachea, A. A. Aligia

We consider an extended Hubbard model with nearest-neighbor correlated hopping and next nearest-neighbor hopping t' obtained as an effective model for cuprate superconductors. Usin…

Does long-range antiferromagnetism help or inhibit superconductivity?

Liliana Arrachea, A. A. Aligia

We analyze the possible existence of a superconducting state in a background with long-range antiferromagnetism. We consider a generalized Hubbard model with nearest-neighbor corre…
