Abstract:

We discuss the consequences of including both electron-phonon and electron-electron couplings multi-band models, focusing on numerical studies of a one-dimensional two-band model in the intermediate regime for both coupling strengths. Spin-Pieierls as well as long-period, frustrated ground states are identified, reminiscent of those found in antiferromagnetic next-nearest neighbor ANNNI models. We speculate on experimentally observable signatures of this rich phase diagram.... Electron-electron couplings, Multiband and multiorbital models, High-temperature superconductors
