SUMMARY:RUN Colloquium: Plasmonic Twistronics: Ultrafast Vector Microscopy
DESCRIPTION:Here we introduce a new technique\, time-resolved vector microscopy\, that enables us to compose entire movies on a sub-femtosecond time scale and a 10 nm scale of the electric field vectors of surface plasmon polaritons. Depending on the shape and geometrical phase\, in combination with the helicity of the excitation beam\, topological plasmonic quasiparticles are created: skyrmions\, merons\, as well as quasicrystalline excitations. We observe their complete field vector dynamics at subfemtosecond time resolution. We expand the concept also to plasmonic twistronics\, where we can identify skyrmion bags. \n\n\n\n\n\nProf. Dr. Harald Gießen
