Orbital Order Effect of Two-Dimensional Spin Gap System for CaV4O9
Nobuyuki Katoh, Masatoshi Imada
Effects of possible orbital order in magnetic properties of two-dimensional spin gap system for CaVO are investigated theoretically. After analyzing experimental data, we s…

Impurity Effect on Spin Ladder System
Yukitoshi Motome, Nobuyuki Katoh, Nobuo Furukawa +1
Effects of nonmagnetic impurity doping in a spin ladder system with a spin gap are investigated by the exact diagonalization as well as by the variational Monte Carlo calculations.…

Spin Gap in Two-Dimensional Heisenberg Model for CaVO
Nobuyuki Katoh, Masatoshi Imada
We investigate the mechanism of spin gap formation in a two-dimensional model relevant to Mott insulators such as CaVO. From the perturbation expansion and quantum Monte Ca…
