Some New Exact Ground States for Generalize Hubbard Models
arXiv:cond-mat/9802010 · doi:10.1209/epl/i1998-00210-x
Abstract
A set of new exact ground states of the generalized Hubbard models in arbitrary dimensions with explicitly given parameter regions is presented. This is based on a simple method for constructing exact ground states for homogeneous quantum systems.
