Topological dynamics and excitations in lasers and condensates with saturable gain or loss
Simon Malzard, Emiliano Cancellieri, Henning Schomerus
We classify symmetry-protected and symmetry-breaking dynamical solutions for nonlinear saturable bosonic systems that display a non-hermitian charge-conjugation symmetry, as realiz…

Topologically protected defect states in open photonic systems with non-hermitian charge-conjugation and parity-time symmetry
Simon Malzard, Charles Poli, Henning Schomerus
We show that topologically protected defect states can exist in open (leaky or lossy) systems even when these systems are topologically trivial in the closed limit. The states appe…
