DOI: 10.1002/adma.202300054
Abstract: Synthetic photonic materials exploiting the quantum concept of parity–time (PT) symmetry lead to an emerging photonic paradigm—non‐Hermitian photonics, which is revolutionizing the photonic sciences. The non‐Hermitian photonics dealing with the interplay between gain and loss… read more here.
