SUMMARY:Colloquium: Photopharmacology Across Time and Space: Molecular Insights via X-ray Free Electron Lasers
DESCRIPTION:RUN auditorium \n\n\n\nDr. Jörg Standfuss  \n\n\n\nLab. for Biomolecular Research\, PSI Center for Life Sciences\, Switzerland \n\n\n\nStructural biology has been critical for our understanding of how proteins work on the molecular level. However\, resolving the temporal evolution of biological macromolecules in response to activating stimuli—such as the binding of small molecular ligands or drug molecules—remains a challenge. In recent years\, our research group has leveraged X-ray Free Electron Laser facilities to experimentally investigate how retinal-binding rhodopsins\, acting as pumps\, channels\, or light sensors\, are activated at the atomic level across a wide range of time scales. \n\n\n\n\n\n\n\n\n\nf \n\n\n\n\nSee announcement\n\n\n\n\n\n\nIn our latest experiments at the Swiss X-ray Free Electron Laser\, we explored how photoactive azobenzene compounds\, mimicking retinal\, can be used to trigger protein dynamics for structural studies. My presentation will focus on the dissociation dynamics of the photopharmacological drug candidate azo-combretastatin A4 from tubulin\, capturing events from the initial photochemical reaction in the femtosecond range\, through the disruption of high-affinity protein-ligand interactions in nanoseconds\, adaptation of the binding pocket in microseconds\, and the eventual release of the compound in milliseconds. I will discuss the relevance of these findings for our understanding of how anti-cancer drugs destabilize the microtubule network. Furthermore\, I will propose the use of azobenzene-based photoswitches to trigger G protein-coupled receptors and other pharmacologically relevant targets in time-resolved structural biology experiments.

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

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:RTG Colloquium: Excitations in condensed matter:From theory to real materials II
DESCRIPTION:The second lecture on excitations in condensed matter will cover electronic excitations in semiconductors and dielectrics\, where the electron-hole interaction in the electronically excited state\, the exciton\, is key. We will explain how the electron-hole interaction arises from Hartree-Fock theory and discuss the limitations of time-dependent density functional theory and Hartree-Fock for the study of excitons. The lecture will then introduce the GW+Bethe-Salpeter method\, the standard for studying excitons in condensed matter with an atomistic description. \n\n\n\n\n\n\n\nJan Wilhelm

SUMMARY:RTG Colloquium:Excitations in condensed matter: from theory to real materials I
DESCRIPTION:This lecture series on excitations in condensed matter will explore electronic excitations\, linking theoretical concepts and experimental observations. The first lecture will cover ground-state and excited-state solutions of the many-body Schrödinger equation for electrons and nuclei. We will illustrate how these solutions are linked to motion on the nanoscale with examples from ultrafast nanoscience and biochemistry. We will also discuss time-dependent density functional theory\, highlighting its success in studying plasmons\, the electronic excitations in metals. \n\n\n\n\n\n\n\nJan Wilhelm
