Block Spin Density Matrix of the Inhomogeneous AKLT Model
Ying Xu, Hosho Katsura, Takaaki Hirano +1
We study the inhomogeneous generalization of a 1-dimensional AKLT spin chain model. Spins at each lattice site could be different. Under certain conditions, the ground state of thi…

Entanglement and Density Matrix of a Block of Spins in AKLT Model
Ying Xu, Hosho Katsura, Takaaki Hirano +1
We study a 1-dimensional AKLT spin chain, consisting of spins in the bulk and at both ends. The unique ground state of this AKLT model is described by the Valence-Bond-So…

Entanglement in an SU(n) Valence-Bond-Solid State
Hosho Katsura, Takaaki Hirano, Vladimir E. Korepin
We investigate entanglement properties in the ground state of the open/periodic SU() generalized valence-bond-solid state consisting of representations of SU(). We obtain exa…
