Classification of symmetry-enriched topological quantum spin liquids
Weicheng Ye, Liujun Zou
We present a systematic framework to classify symmetry-enriched topological quantum spin liquids in two spatial dimensions. This framework can deal with all topological quantum spi…
Anomaly of -Dimensional Symmetry-Enriched Topological Order from -Dimensional Topological Quantum Field Theory
Weicheng Ye, Liujun Zou
Symmetry acting on a (2+1) topological order can be anomalous in the sense that they possess an obstruction to being realized as a purely (2+1) on-site symmetry. In this pape…
Topological characterization of Lieb-Schultz-Mattis constraints and applications to symmetry-enriched quantum criticality
Weicheng Ye, Meng Guo, Yin-Chen He +2
Lieb-Schultz-Mattis (LSM) theorems provide powerful constraints on the emergibility problem, i.e. whether a quantum phase or phase transition can emerge in a many-body system. We d…
Ultraviolet-Infrared Mixing in Marginal Fermi Liquids
Weicheng Ye, Sung-Sik Lee, Liujun Zou
When Fermi surfaces (FSs) are subject to long-range interactions that are marginal in the renormalization-group sense, Landau Fermi liquids are destroyed, but only barely. With the…
