Multi-dimensional parameter space of higher-order exceptional points induced by Brillouin optoacoustics
Grigorii Slinkov, Anton Montag, Julius T. Gohsrich +4
Exceptional points (EPs) are degeneracies in the spectrum of non-Hermitian systems, where both the eigenvalues and eigenvectors coalesce. In the vicinity of an n-th order EP, the e…

Higher-order exceptional points in a multimode continuum optoacoustic system
Anton Montag, Julius T. Gohsrich, Quentin Levoy +2
Exceptional points appear in non-Hermitian systems as degeneracies, where not only eigenvalues but also eigenvectors coalesce. They are of great theoretical and experimental intere…
