Optical Realization of Relativistic Non-Hermitian Quantum Mechanics
Light propagation in distributed-feedback optical structures with gain or loss regions is shown to provide an accessible laboratory tool to visualize in optics the spectral properties of the one-dimensional Dirac equation with non-Hermitian interactions. Spectral singularities and $\mathcal{P}\mathcal{T}$ symmetry breaking of the Dirac Hamiltonian are shown to correspond to simple …
