Topological phases and quantum criticality from Chern-Simons-matter theories
Yunchao Hao, Yingcheng Li, Kangle Li +1
Motivated by recent numerical studies where various Chern-Simons-matter theories emerge, we analytically study topological phases and quantum criticality in two-dimensional…

Microscopic universal theory of symmetry-enriched topological quantum spin liquids
Yingcheng Li, Liujun Zou
An ultimate theory of a phase of matter should describe all its universal properties via quantities that are measurable numerically and experimentally. In this work, we present a m…

Non-Abelian Particle-Loop, Fracton, and Planon Condensation in Cage-Net Models
Yifei Wang, Yu Zhao, Yingcheng Li +2
We present a framework for non-Abelian p-loop, fracton, and planon condensation in 3+1 dimensions by constructing extended cage-net fracton models using decoupled layers of the Hu-…
