SUMMARY:RTG Colloquium: Complexity with a purpose: Long range collective vibrations steering protein conformational change
DESCRIPTION:14:00 h \n\n\n\n\n\n\n\n\n\n\n\nRUN auditorium \n\n\n\nProf. Dr. Andrea Markelz \n\n\n\nUniversity at Buffalo College of Arts and Sciences \n\n\n\n\n\n\n\nThe evolutionary advantage of the large-scale structure of proteins surrounding the biochemically active site is not readily apparent. It has been speculated that the structural dynamics provide long-range control of access to the active site. Through anisotropic terahertz micro-spectroscopy (ATM) measurements we find that the photo initiation of orange carotenoid protein’s (OCP) photocycle is accompanied with switching in the protein structural vibrations\, before long range structural change can occur. The ATM spectral changes are reversible and calculations reproduce the changes in ATM spectra\, with features red shifted from the measurements. Averaging the vibrational displacement autocorrelation matrix over the spectrally relevant region and thermally occupied starting configurations finds changes in the correlations for residues 80-113 with residues 151-164\, and for residues 280-291 with residues 265-275. These regions are those previously predicted to be involved in the structural modification necessary for a critical step in the photocycle. The results provide the first evidence that structural vibrational change can actuate conformational change for function.

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:Ultrafast electronics on chip
DESCRIPTION:Colloquium: Dr. Eryin Wang \n\n\n\n\n\nUltrafast optical control has emerged as a powerful tool for manipulating the functional properties ofquantum materials [1\,2]. These non‐equilibrium phenomena occur at femto‐ to pico‐second timescaleswhich are intrinsic to the microscopic interactions between electron\, spin and lattice\, offering thepotential for faster on‐chip electronics. A key challenge for application is “reading” the electricalresponse\, namely voltage or current signals\, of photo‐induced transient phases. Here I present twoexamples [3\,4] of using newly developed on‐chip ultrafast transport techniques [5] to detect theelectrical signals from light‐induced superconducting‐like state in K3C60 [6]. \n\n\n\n \n\n\n\n[1] Disa\, A.S. et al.\, Nat.

SUMMARY:Inaugural Symposium
DESCRIPTION:Innovation in fundamental science and in quantum-\, nano- and bio-technologies depends on a thorough understanding of the inner workings of custom-tailored materials. High-resolution microscopy has provided still images of the elementary building blocks of matter. Because the nanoworld is constantly in motion\, still images are often not enough. For instance\, tailoring functionalities of quantum materials or controlling biochemical reactions would be facilitated by direct ultraslow motion pictures visualizing the interplay of the nanoscopic building blocks of matter in space and time. \nThe bar is set high since the relevant elementary processes often evolve on time scales as short as femtoseconds (1 fs = 10-15 s) or even attoseconds (1 as = 10-18 s). Developing concepts that allow for simultaneous resolution of ultrashort time and length scales is hence one of the key scientific and technological challenges of this century. \nHosted by the brand-new Regensburg Center for Ultrafast Nanoscopy (RUN)\, the Symposium “The Nanoworld in Motion” will showcase the latest ultrafast nanoscopy principles and their applications to clarify urgent questions on dynamics of systems ranging from individual molecules to complex biomolecular and solid-state nanostructures.
