Pomeranchuk instability in doped graphene
Belen Valenzuela, Maria A. H Vozmediano
The density of states of graphene has Van Hove singularities that can be reached by chemical doping and have already been explored in photoemission experiments. We show that in the…
Energy Scales in the Raman spectrum of electrons and hole doped cuprates within competing scenarios
B. Valenzuela, E. Bascones
Recent experiments in underdoped hole-doped cuprates have shown the presence of two energy scales in the Raman spectrum in the superconducting state. This feature has a natural exp…
Phenomenological description of the two energy scales in underdoped superconducting cuprates
B. Valenzuela, E. Bascones
Raman and ARPES experiments have demonstrated that in superconducting underdoped cuprates nodal and antinodal regions are characterized by two energy scales instead of the one expe…
Non-resonant Raman response of inhomogeneous structures in the electron doped Hubbard model
Belén Valenzuela
We calculate the non-resonant Raman response, the single particle spectra and the charge-spin configuration for the electron doped Hubbard model using unrestricted Hartree-F…
Anisotropic transport in the overdoped High-Tc superconductors within the Van Hove scenario
Belen Valenzuela, Maria A. H. Vozmediano
Recent Raman experiments [F. Venturini et al., Phys. Rev. Lett. {\bf 89}, 107003-1,(2002)] done in have found that antinodal quasiparticles become insulatin…
Incipient quantum melting of the one-dimensional Wigner lattice
S. Fratini, B. Valenzuela, D. Baeriswyl
A one--dimensional tight--binding model of electrons with long--range Coulomb interactions is studied in the limit where double site occupancy is forbidden and the Coulomb coupling…
