Possible Ordered States in the 2D Extended Hubbard Model
Masakazu Murakami
Possible ordered states in the 2D extended Hubbard model with on-site (U>0) and nearest-neighbor (V) interaction are examined near half filling, with emphasis on the effect of fini…
Backward Scattering and Coexistent State in Two-Dimensional Electron System
Masakazu Murakami, Hidetoshi Fukuyama
The results of the mean field studies on the effects of the backward scattering with large momentum transfer in a two-dimensional electron system are extended to the case with vari…
Effects of the Backward Scattering in Two-Dimensional Electron System
Masakazu Murakami, Hidetoshi Fukuyama
Effects of the backward scattering with large momentum transfer are examined in two-dimensional electron system with a special emphasis on electrons around (,0), (0,). The ph…
Effects of Umklapp Scattering on Electronic States in One Dimension
Masakazu Murakami, Hidetoshi Fukuyama
The effects of Umklapp scattering on electronic states are studied in one spatial dimension at absolute zero. The model is basically the Hubbard model, where parameters characteriz…
