Continuous quantum phase transition between two topologically distinct valence bond solid states associated with the same spin value

Dong Zheng, Guang-Ming Zhang, Tao Xiang +1

We propose a simple one-dimensional spin-2 Hamiltonian, which exhibits two topologically distinct valence bond solid states in different exactly solvable limits. We then construct…
