SUMMARY:RTG Colloquium: Accurate theoretical methods for structural characterization of complex materials
DESCRIPTION:Spectroscopy is crucial for establishing structure-property relationships as it provides detailed information about the molecular composition and electronic structure of materials. This data is essential for correlating specific structural features with material properties\, thereby guiding the design and optimization of new materials. I will discuss our recent advances in accurately predicting core-level and vibrational spectra of complex materials. For core-level spectroscopy\, we developed highly accurate but computationally expensive methods based on Green’s function theory in the GW approximation. Calculations for amorphous materials\, which require computational models with several hundred atoms\, were enabled by devising new efficient algorithms and combining these methods with machine-learning approaches. In addition\, I will discuss computational approaches to vibrational spectroscopy that not only allow for the structural characterization of the final layered framework materials but also enable the monitoring of synthesis progress. \n\n\n\n\n\n\n\nDr. Dorothea Golze

SUMMARY:RUN Colloquium:Plasmonic Twistronics: Ultrafast Vector Microscopy
DESCRIPTION:Location: H 51 \n\n\n\nHere 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\n\n\nHarald Gießen
