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…
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…
Optically controlled orbital angular momentum generation in a polaritonic quantum fluid
Samuel M. H. Luk, Nai-Hang Kwong, Przemyslaw Lewandowski +2
Applications of the orbital angular momentum (OAM) of light range from the next generation of optical communication systems to optical imaging and optical manipulation of particles…
