| Klein spin model ground states on general lattices (2006) | |||||||||
Abstract | |||||||||
| We prove that in short range Klein spin models on general lattices, all ground states are of the dimer type- each fundamental plaquette must host at least one singlet. These ground states are known to rigorously exhibit high dimensional fractionalization. When combined with a recent theorem, this establishes that Klein spin models exhibit topological order on the pyrochlore and checkerboard lattices.. Comment: 4 pages, 3 figures | |||||||||
