Charge instabilities near a Van Hove singularity
J. Gonzalez
The charge instabilities of electron systems in the square lattice are analyzed near the Van Hove singularity by means of a wilsonian renormalization group approach. We show that t…

Microscopic description of d-wave superconductivity by Van Hove nesting in the Hubbard model
J. Gonzalez
We devise a computational approach to the Hubbard model that captures the strong coupling dynamics arising when the Fermi level is at a Van Hove singularity in the density of state…

Charge-density-wave formation by Van Hove nesting in the α-phase of Sn/Ge(111)
J. Gonzalez
We study the role of electron correlations in the formation of the surface charge-density-wave state in the Sn/Ge(111) interface. The Fermi energy of the overlayer is treated as a…
