Topological phase transitions driven by non-Hermiticity in quantum spin Hall insulators
Topological phase transitions driven by non-Hermiticity in quantum spin Hall insulators
The interplay between non-Hermiticity and topology opens an exciting avenue for engineering novel topological matter with unprecedented properties. While previous studies have mainly focused on one-dimensional systems or Chern insulators, here we investigate topological phase transitions to/from quantum spin Hall (QSH) insulators driven by non-Hermiticity. We show that a trivial …
