  Parity–time-symmetric photonic topological insulator

  The authors propose a non-Hermitian topological insulator with a real-valued energy spectrum based on a periodically driven Floquet model implemented in a photonic platform where generalized parity–time symmetry is protected against spontaneous symmetry breaking under a spatiotemporal gain and loss distribution.

  Fermionic time-reversal symmetry in a photonic topological insulator

  Counter-propagating chiral edge states are demonstrated in a photonic structure able to effectively incorporate fermionic time-reversal symmetry, thus providing the photonic implementation of an electronic topological insulator.
