Non-Hermitian degeneracy of two unbound states
E. Hernandez, A. Jauregui, A. Mondragon
We solved numerically the implicit, trascendental equation that defines the eigenenergy surface of a degenerating isolated doublet of unbound states in the simple but illustrative…

Unfolding a degeneracy point of two unbound states: Crossings and anticrossings of energies and widths
E. Hernandez, A. Jauregui, A. Mondragon +1
We show that when an isolated doublet of unbound states of a physical system becomes degenerate for some values of the control parameters of the system, the energy hypersurfaces re…
