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…
A linear algebra-based approach to understanding the relation between the winding number and zero-energy edge states
Chen-Shen Lee
The one-to-one relation between the winding number and the number of robust zero-energy edge states, known as bulk-boundary correspondence, is a celebrated feature of 1d systems wi…
Winding number and Zak phase in multi-band SSH models
Chen-Shen Lee, Iao-Fai Io, Hsien-chung Kao
We use multi-band SSH models to demonstrate a prescription for calculating the correct Zak phase and winding number of multi-band systems. We verify our prescription by comparing t…
