Skyrmions in scalar fields of non-Hermitian optical microcavities: spontaneous formation, nonlinear control, and optical forces
Jan Wingenbach, Roman Lebs, Xuekai Ma +5
Topological textures of light offer powerful routes for structuring optical fields, controlling wave transport, and manipulating matter. Skyrmions, long studied as topological soli…

Exceptional rings in nonlinear non-Hermitian planar optical microcavities: implementation, signal enhancement, and topology
Jan Wingenbach, Laura Ares, Xuekai Ma +4
Non-Hermitian systems hosting exceptional points (EPs) exhibit signal enhancement and unconventional mode dynamics. Going beyond isolated EPs, here we report on the existence of ex…
