Ground-State Properties of the Two-Band Model for Halogen-Bridged Metal Complexes
arXiv:cond-mat/9810111
Abstract
Based on a symmetry argument, we systematically reveal Hartree-Fock broken-symmetry solutions of the one-dimensional two-band extended Peierls-Hubbard model. Performing numerical investigations as well, the possibility of novel density-wave states appearing is argued.
