Topological and hyperbolic dielectric materials from chirality-induced charge-parity symmetry

Parity-time (\mathcal{PT})symmetry, originally conceived for non-Hermitian open quantum systems, has opened an exciting avenue towards coherent control of light for significant applications. Here we propose a paradigm towards non-Hermitian photonics based on the charge-parity (\mathcal{CP})symmetry, in which the charge conjugation and parity symmetries are broken individually but preserved jointly. Such a symmetry-breaking scheme induces a...
