Classification of matrix product ground states corresponding to one dimensional chains of two state sites of nearest neighbor interactions

By Amir H. Fatollahi, Mohammad Khorrami, Ahmad Shariati and Amir Aghamohammadi


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.Comment: 17 pages, LaTeX2
