Surface chiral Abelian topological order on multilayer cluster Mott insulators
Xu-Ping Yao, Chao-Kai Li, Gang v. Chen
The surface states of a symmetry protected topological state can have many possibilities. Here we propose a chiral Abelian topological order on a distinct surface of a multilayer-s…

Nematic correlations and nematic Berezinskii-Kosterlitz-Thouless transition in spin-1 kagome lattice antiferromagnets
Chun-Jiong Huang, Xu-Ping Yao, Gang v. Chen
Nematicity plays an important role in strongly correlated electron systems. We explore the spin nematicity of a spin-1 kagome lattice antiferromagnet with the bilinear-biquadratic…
