SU(3) quantum critical model emerging from a spin-1 topological phase
Wen-Jia Rao, Guo-Yi Zhu, Guang-Ming Zhang
Different from the spin-1 Haldane gapped phase, we propose a novel SO(3) spin-1 matrix product state (MPS), whose parent Hamiltonian includes three-site spin interactions. From the…
Quantum antiferromagnetic Heisenberg half-odd integer spin model as the entanglement Hamiltonian of the integer spin Affleck-Kennedy-Lieb-Tasaki states
Wen-Jia Rao, Guang-Ming Zhang, Kun Yang
Applying a symmetric bulk bipartition to one-dimensional Affleck-Kennedy-Lieb-Tasaki valence bond solid (VBS) states for the integer spin-S Haldane gapped phase, we can create an a…
Emergent infinite-randomness fixed points from the extensive random bipartitions of the spin-1 Affleck-Kennedy-Lieb-Tasaki topological state
Min Lu, Wen-Jia Rao, Rajesh Narayanan +2
Quantum entanglement under an extensive bipartition can reveal the critical boundary theory of a topological phase in the parameter space. In this study we demonstrate that the inf…
Critical entanglement spectrum of one-dimensional symmetry protected topological phases
Wen-Jia Rao, Xin Wan, Guang-Ming Zhang
Under an appropriate symmetric extensive bipartition in a one-dimensional symmetry protected topological (SPT) phase, a bulk critical entanglement spectrum can be obtained, resembl…
Disentangling topological degeneracy in the entanglement spectrum of one-dimensional symmetry protected topological phases
Wen-Jia Rao, Guang-Ming Zhang, Kun Yang
One-dimensional valence bond solid (VBS) states represent the simplest symmetry protected topological phases. We show that their ground state entanglement spectrum contains both to…
