Effect of Electron-Phonon Interaction Range for a Half-Filled Band in One Dimension. Hohenadler, M., Assaad, F. F., & Fehske, H. Physical Review Letters, 109(11):116407, September, 2012. ![Effect of Electron-Phonon Interaction Range for a Half-Filled Band in One Dimension [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex We demonstrate that fermion-boson models with nonlocal interactions can be simulated at finite band filling with the continuous-time quantum Monte Carlo method. We apply this method to explore the influence of the electron-phonon interaction range for a half-filled band in one dimension, covering the full range from the Holstein to the Fröhlich regime. The phase diagram contains metallic, Peierls, and phase-separated regions. Nonlocal interactions suppress the Peierls instability, and thereby lead to almost degenerate power-law exponents for charge and pairing correlations.
