Exact ground states of quantum spin-2 models on the hexagonal lattice
Marc Andre Ahrens, Andreas Schadschneider, Johannes Zittartz
We construct exact non-trivial ground states of spin-2 quantum antiferromagnets on the hexagonal lattice. Using the optimum ground state approach we determine the ground state in d…

Exact ground states of spin-2 chains
M. A. Ahrens, A. Schadschneider, J. Zittartz
We use the matrix product approach to construct all optimum ground states of general anisotropic spin-2 chains with nearest neighbour interactions and common symmetries. These stat…
