(pdf)
Tian Lan, Liang Kong, Xiao-Gang Wen
arXiv:1602.05946
Classified 2+1D gapped phases for bosons/fermions with any finite symmetry,
using three braided fusion categories E < C < M.

Xie Chen, Zheng-Cheng Gu, Zheng-Xin Liu, and Xiao-Gang Wen
arXiv:1106.4772
Introduced group cohomology theory into condensed matter physics to describe
short-range entangled phases with symmetry for interacting bosons.
