Parity-Time Symmetry Breaking beyond One Dimension: The Role of Degeneracy
We consider the role of degeneracy in parity-time (PT) symmetry breaking for non-Hermitian wave equations beyond one dimension. We show that if the spectrum is degenerate in the absence of T breaking, and T is broken in a generic manner (without preserving other discrete symmetries), then the standa...
