Charge Ordering and Spin gap in NaV_2O_5
Hitoshi Seo, Hidetoshi Fukuyama
A possible ground state of NaV_2O_5 is proposed based on the Hartree approximation for both on-site and intersite Coulomb interactions. The results indicate that the intersite Coul…

Frustrated Spin System in theta-(BEDT-TTF)_2RbZn(SCN)_4
Hitoshi Seo, Hidetoshi Fukuyama
The origin of the spin gap behavior in the low-temperature dimerized phase of theta-(BEDT-TTF)_2RbZn(SCN)_4 has been theoretically studied based on the Hartree-Fock approximation f…

On the Spin Gap Phase in lambda-(BETS)_2GaX_zY_{4-z}
Hitoshi Seo, Hidetoshi Fukuyama
The nature of the insulating ground state in quasi-two-dimensional organic conductor lambda-(BETS)_2GaX_zY_{4-z}, where the existence of a spin gap is suggested by susceptibility m…
