Exceptional Points in a Non-Hermitian Topological Pump
Wenchao Hu, Hailong Wang, Perry Ping Shum +1
We investigate the effects of non-Hermiticity on topological pumping, and uncover a connection between a topological edge invariant based on topological pumping and the winding num…

Measurement of a topological edge invariant in a microwave network
Wenchao Hu, Jason Cornelius Pillay, Kan Wu +3
We report on the measurement of topological invariants in an electromagnetic topological insulator analog formed by a microwave network, consisting of the winding numbers of scatte…
