Dual topological nonlinear sigma models of theory by dimensional reduction and monopole operators
Zhengzhi Wu, Linhao Li
Nonlinear models (NLSM) with topological terms, i.e., Wess-Zumino-Witten (WZW) terms, or topological NLSM, are potent descriptions of many critical points and phases beyond the…
Duality viewpoint of criticality
Linhao Li, Yuan Yao
In this work, we study quantum many-body systems which are self-dual under duality transformation connecting different symmetry protected topological (SPT) phases. We provide a geo…
Boundary conditions and anomalies of conformal field theories in 1+1 dimensions
Linhao Li, Chang-Tse Hsieh, Yuan Yao +1
We study a relationship between conformally invariant boundary conditions and anomalies of conformal field theories (CFTs) in 1+1 dimensions. For a given CFT with a global symmetry…
Decorated Defect Construction of Gapless-SPT States
Linhao Li, Masaki Oshikawa, Yunqin Zheng
Symmetry protected topological (SPT) phases are one of the simplest, yet nontrivial, gapped systems that go beyond the Landau paradigm. In this work, we study an extension of the n…
Duality, Criticality, Anomaly, and Topology in Quantum Spin-1 Chains
Hong Yang, Linhao Li, Kouichi Okunishi +1
In quantum spin-1 chains, there is a nonlocal unitary transformation known as the Kennedy-Tasaki transformation , which defines a duality between the Haldane phase a…
