Correlation Effect on the Two-Dimensional Peierls Phase
Shutaro Chiba, Yoshiyuki Ono
The effect of the electron-electron (e-e) interaction on the Peierls lattice distortions due to the electron-lattice (e-l) interaction is studied in the two-dimensional Peierls-Hub…

Multi-Modes Phonon Softening in Two-Dimensional Electron-Lattice System
Shutaro Chiba, Yoshiyuki Ono
Phonon dispersion in a two-dimensional electron-lattice system described by a two-dimensional square-lattice version of Su-Schrieffer-Heeger's model and having the half-filled elec…
