Degeneracies and symmetry breaking in pseudo-Hermitian matrices
Real eigenvalues of pseudo-Hermitian matrices, such as real matrices and PT−symmetric matrices, frequently split into complex conjugate pairs. This is accompanied by the breaking of certain symmetries of the eigenvectors and, typically, also a drastic change in the behavior of the system. In this pa...
