Abstract
Self-consistent solutions to a generalized Su-Schrieffer-Heeger model on a 2-dimensional square lattice are investigated. Away from half-filling, spatially inhomogeneous phases are found. Those phases may have topological structures on the flux order, large unit cell bond order, localized bipolarons, or they are simply short-range ordered and glassy. They have an universal feature of always possessing a gap at the Fermi level.
