Coulomb parameters and photoemission for the molecular metal TTF-TCNQ
Laura Cano-Cortés, Andreas Dolfen, Jaime Merino +4
We employ density-functional theory to calculate realistic parameters for an extended Hubbard model of the molecular metal TTF-TCNQ. Considering both intra- and intermolecular scre…
Charge Fluctuations in Geometrically Frustrated Charge Ordering System
Hitoshi Seo, Kenji Tsutui, Masao Ogata +1
Effects of geometrical frustration in low-dimensional charge ordering systems are theoretically studied, mainly focusing on dynamical properties. We treat extended Hubbard models a…
Theoretical Aspects of Charge Ordering in Molecular Conductors
Hitoshi Seo, Jaime Merino, Hideo Yoshioka +1
Theoretical studies on charge ordering phenomena in quarter-filled molecular (organic) conductors are reviewed. Extended Hubbard models including not only the on-site but also the…
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…
