Skyrmion topology of scalar waves in real and momentum space

Nai H. Kwong, Ewan M. Wright, Jan Wingenbach +4

Generalizations of magnetic skyrmions to the context of other areas of physics, such as plasmonics, optics (including microcavity polaritons) and even water waves have become an im…

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…

Polarization- and wave-vector selective optical metasurface with near-field coupling

Helene Wetter, Jan Wingenbach, Falk Rehberg +3

Metasurfaces are a powerful tool for manipulating light using small structures on the nanoscale. In most meta-surfaces, near-field couplings are treated as unfavorable perturbation…

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…

Universal Topology of Exceptional Points in Nonlinear Non-Hermitian Systems

N. H. Kwong, Jan Wingenbach, Laura Ares +4

Exceptional points (EPs) are non-Hermitian degeneracies where eigenvalues and eigenvectors coalesce, giving rise to unusual physical effects across scientific disciplines. The conc…

Optically and remotely controlling localization of exciton polariton condensates in a potential lattice

Qiang Ai, Jan Wingenbach, Xinmiao Yang +6

Exciton polaritons are inherently tunable systems with adjustable potential landscape. In this work we show that exciton polariton condensates can be selectively localized in a fix…

Dynamics of phase defects trapped in optically imprinted orbits in dissipative binary polariton condensate

Jan Wingenbach, Matthias Pukrop, Stefan Schumacher +1

We study the dynamics of phase defects trapped in a finite optically imprinted ring lattice in binary polariton condensates, under the influence of the cross-interaction (CI) betwe…
