Towards a complete classification of non-chiral topological phases in 2D fermion systems
Jing-Ren Zhou, Qing-Rui Wang, Zheng-Cheng Gu
In recent years, fermionic topological phases of quantum matter has attracted a lot of attention. In a pioneer work by Gu, Wang and Wen, the concept of equivalence classes of fermi…
