Degeneracy of Ground State in Two-dimensional Electron-Lattice System
Tetsuya Hamano, Yoshiyuki Ono
We discuss the ground state of a two dimensional electron-lattice system described by a Su-Schrieffer-Heeger type Hamiltonian with a half-filled electronic band, for which it has b…

Peierls Distortion in Two-Dimensional Tight-Binding Model
Yoshiyuki Ono, Tetsuya Hamano
The Peierls distortions in a two-dimensional electron-lattice system described by a Su-Schrieffer-Heeger type model extended to two-dimensions are numerically studied for a square…
