Critical theory of the topological quantum phase transition in a spin-2 chain

Hong-Chen Jiang, Stephan Rachel, Zheng-Yu Weng +2

We systematically study the phase diagram of S=2 spin chain, by means of density-matrix renormalization group and exact diagonalization methods and confirm the presence of a dimer…

Topological quantum phase transition in an S=2 spin chain

Jiadong Zang, Hong-Chen Jiang, Zheng-Yu Weng +1

We construct a model Hamiltonian for S = 2 spin chain, where a variable parameter $α$ is introduced. The edge spin is S = 1 for $α = 0$ , and S = 3/2 for $α = 1$ . Due to the topologic…
