Connection between Free-Fermion and Interacting Crystalline Symmetry-Protected Topological Phases
Chen-Shen Lee, Ken Shiozaki, Chang-Tse Hsieh
We present a framework for investigating the effects of interactions on crystalline symmetry-protected topological (SPT) phases. Within this framework, one can establish a direct c…

Crystalline-equivalent topological phases of many-body fermionic systems in one dimension
Chen-Shen Lee, Ken Shiozaki, Chang-Tse Hsieh
We explore one-dimensional fermionic symmetry-protected topological (SPT) phases related by the crystalline equivalence principle. In particular, we study charge-conserving many-bo…
