Charge order and phonon renormalizations: Possible implications for cobaltates
M. Bejas, A. Greco, A. Foussats
Several experimental and theoretical studies in cobaltates suggest the proximity of the system to charge ordering (CO). We show, qualitatively, in the frame of a model couple…

Electron-phonon interaction dressed by electronic correlations near charge ordering as the origin for superconductivity in cobaltates
A. Foussats, A. Greco, M. Bejas +1
We consider possible routes to superconductivity in hydrated cobaltates Na_xCoO_2.yH_2O on the basis of the t-J-V model plus phonons on the triangular lattice. We studied the stabi…

Non-Fermi liquid behavior in nearly charge ordered layered metals
J. Merino, A. Greco, N. Drichko +1
Non-Fermi liquid behavior is shown to occur in two-dimensional metals which are close to a charge ordering transition driven by the Coulomb repulsion. A linear temperature dependen…
