Breaking of PT Symmetry in Bounded and Unbounded Scattering Systems

Breaking of PT Symmetry in Bounded and Unbounded Scattering Systems

PT-symmetric scattering systems with balanced gain and loss can undergo a symmetry-breaking transition in which the eigenvalues of the nonunitary scattering matrix change their phase shifts from real to complex values. We relate the PT-symmetry-breaking points of such an unbounded scattering system...
