A modified form of the polar model of crystals
Leonid Didukh
A model for description of materials with narrow energy bands is proposed. It is shown that in narrow-band materials electron-hole symmetry is absent in contrast to the Hubbard mod…

Temperature-Induced Metal-Insulator Transition in a Narrow-Band Model with Non-Equivalent Hubbard Subbands at Half-Filling
Leonid Didukh, Vasyl Hankevych
In the previous papers (Journ. of Phys. Stud. 2, 362 (1998); cond-mat/9811213) we have studied metal-insulator transition in a generalized Hubbard model with correlated hopping at…
