PT-symmetric waveguide
Broken PT-symmetry in a waveguide with non-Hermitian boundary conditions.
The emergence of real eigenvalues (blue and green balls) and complex conjugated pairs of eigenvalues (red and cyan balls) from the continuous spectrum (thick white line) and their trajectories (with apparent collisions) in the complex plane as a boundary coupling parameter increases.
