Non-Hermitian topological light steering
TLDR
By strategically interfacing non-Hermitian and topological physics, this approach provides a route to controlling topologically protected light paths in an integrated optical platform and demonstrates arbitrary, robust light steering in reconfigurable non- hermitian junctions.Abstract:
By strategically interfacing non-Hermitian and topological physics, we demonstrate arbitrary, robust light steering in reconfigurable non-Hermitian junctions, in which chiral topological states can propagate at an interface of the gain and loss domains.read more

Highlighting photonics: looking into the next decade
TL;DR: In this paper, the authors highlight a few emerging trends in photonics that they think are likely to have major impact at least in the upcoming decade, spanning from integrated quantum photonics and quantum computing, through topological/non-Hermitian photonics, to AI-empowered nanophotonics and photonic machine learning.

Higher-order non-Hermitian skin effect
TL;DR: In this paper, higher-order versions of the non-Hermitian skin effect have been discovered in two-dimensional systems with the system size L×L, where the conventional (first-order) skin effect accompanies O(L2) skin modes, while the second-order skin effect accompanied O (L) corner skin modes.
