Classification of matrix product ground states corresponding to one dimensional chains of two state sites of nearest neighbor interactions
arXiv:1105.0994 · doi:10.1103/PhysRevA.83.042108
Abstract
A complete classification is given for one dimensional chains with nearest neighbor interactions having two states in each site, for which a matrix product ground state exists. The Hamiltonians and their corresponding matrix product ground states are explicitly obtained.
