Mott insulating state in a quarter-filled two-orbital Hubbard chain with different bandwidths
S. Miyashita, Y. Yamashita, K. Yonemitsu +2
We investigate the ground-state properties of the one-dimensional two-band Hubbard model with different bandwidths. The density-matrix renormalization group method is applied to ca…

Spin and Charge Fluctuations and Lattice Effects on Charge Orders in α-(BEDT-TTF)_2I_3
Satoshi Miyashita, Kenji Yonemitsu
The effects of spin and charge fluctuations and electron-phonon couplings on charge ordering in α-(BEDT-TTF)_2I_3 (BEDT-TTF=bis(ethylenedithio)-tetrathiafulvalence) are investigate…
