Formation of rogue waves and modulational instability with zero-wavenumber gain in multicomponent systems with coherent coupling

L Liu, WR Sun, BA Malomed - Physical Review Letters, 2023 - APS
It is known that rogue waves (RWs) are generated by the modulational instability (MI) of the
baseband type. Starting with the Bers-Kaup-Reiman system for three-wave resonant …

Protection of all nondefective twofold degeneracies by antiunitary symmetries in non-Hermitian systems

S Sayyad - Physical Review Research, 2022 - APS
Non-Hermitian degeneracies are classified as defective exceptional points (EPs) and
nondefective degeneracies. While in defective EPs, both eigenvalues and eigenvectors …
