Abstract

Symmetry plays a pivotal role in physics as has been demonstrated in high energy physics, classical physics, and condensed matter physics. In this talk, I will show via several interesting examples that glide symmetry, an intriguing type of crystalline symmetry can greatly enrich topological and non-Hermitian effects. I illustrate first that glide symmetry naturally induces synthetic gauge phases in lattice systems and show how they can affect the interface boundary to induce novel topological Wannier cycles. On the other aspect, I show that glide symmetry can greatly enrich the properties of non-Hermitian systems, leading to unexpected dynamic phases and phase transitions.
