Non-Hermitian Topology and Directional Amplification in Driven-Dissipative Cavity Arrays
… we first develop a unifying framework based on non-Hermitian topology to understand non-reciprocity and directional amplification in driven-dissipative cavity arrays. Specifically, we unveil a one-to-one correspondence between a non-zero topological invariant defined on the spectrum of the …

Topological Insulating States in Photonics and Acoustics
… (PT) symmetric interfaces formed between non-Hermitian amplifying (“gainy”) and lossy topological crystals exhibit PT phase transitions separating phases of lossless and decaying/amplifying topological edge transport. <em>Exceptional points </em>(EPs) are found in these complex-valued …
