Our work introduces the advantages of Floquet PT-symmetry in a practical integrated photonic setting, enabling a powerful platform to observe PT-symmetric phenomena and leverage their extreme features, with applications in nanophotonics, coherent control of nanoscale light amplification and routing....
Here, by demonstrating a parity–time-symmetric topological insulator, we show that topological transport exists beyond these constraints. Implemented on a photonic platform, our non-Hermitian topological system harnesses the complex interplay between a discrete coupling protocol and judiciously placed losses...
Dynamic encircling of an anti-parity-time (anti-PT) symmetric exceptional point (EP) leads to chiral transfer of symmetry-broken modes, which has been explored in various systems except acoustics. In this work, acoustic counterpart of this behavior is numerically demonstrated in coupled waveguide sy...
