Topological Phases Protected By Reflection Symmetry and Cross-cap States
Gil Young Cho, Chang-Tse Hsieh, Takahiro Morimoto +1
Twisting symmetries provides an efficient method to diagnose symmetry-protected topological (SPT) phases. In this paper, edge theories of (2+1)-dimensional topological phases prote…
CPT theorem and classification of topological insulators and superconductors
Chang-Tse Hsieh, Takahiro Morimoto, Shinsei Ryu
We present a systematic topological classification of fermionic and bosonic topological phases protected by time-reversal, particle-hole, parity, and combination of these symmetrie…
Symmetry-protected Topological Phases, Generalized Laughlin Argument and Orientifolds
Chang-Tse Hsieh, Olabode Mayodele Sule, Gil Young Cho +2
We generalize Laughlin's flux insertion argument, originally discussed in the context of the quantum Hall effect, to topological phases protected by non-on-site unitary symmetries,…
