SUMMARY:RTG Colloquium: Zhiyang Zeng
DESCRIPTION:Condensed Matter Dynamics DepartmentMPI for the Structure and Dynamics of Matter\, Hamburg \n\n\n\n\n\nDynamical control of structural orderCoherent excitation of lattice vibrations has emerged as a powerful approach to dynamicallycontrol functional material properties. In this talk\, I will present our recent work on using nonlinearphononics—a mechanism that enables the selective displacement of specific lattice vibrations—tomanipulate structural functionalities with light [1\,2]. In particular\, I will discuss how this approachenables the ultrafast control of chirality [3] and ferroaxial order [4]\, offering new pathways to tailorsymmetry and drive phase transitions in solids on demand. \n\n\n\n[1] Först\, et al.

SUMMARY:RTG Seminar: Yiqi Fang
DESCRIPTION:Shaping electron dynamics with structured light\n\n\n\nFAU Erlangen\, Institute of Laser Physics \n\n\n\n \n\n\n\nLaser-excited electron motions allow the investigation of fundamental physical phenomena with unprecedented resolution in time\, space and energy. Structured light offers new opportunities to tailor and control the optical response of materials\, far beyond the ability of conventional linearly or circularly polarized light. In this talk\, I will show the physics and application of structured light when it interacts with bound electrons in atoms as well as when it interacts with electron pulses in free space. \n\n\n\n \n\n\n\n \n\n\n\n \n\n\n\nVenue: RUN.0.35

SUMMARY:RTG Colloquium: Thomas Taubner
DESCRIPTION:Infrared near-field spectroscopy of few-layer graphene\n\n\n\nRWTH Aachen\, Germany \n\n\n\nInfrared scattering-type scanning-near-field optical microscopy (s-SNOM) enables the imaging of nanostructures with sub-diffraction resolution by elastic light scattering at a sharp tip. s-SNOM also boosted the field of 2D materials by enabling real-space imaging of plasmon- or phonon polaritons\, e.g.\, in graphene and hexagonal Boron Nitride (hBN)\, respectively. Polariton imaging with s-SNOM has allowed for indirectly mapping (grain) boundaries and (stacking) defects in fewlayer Graphene (FLG) via polariton reflection.Here\, I will present how spectroscopic IR s-SNOM is able to determine the local stacking order at nanoscale resolution not only of bare few-layer graphene\, but also when it is encapsulated below hBN layers. I will explain the contrast mechanisms\, mainly based on the characteristic and stacking-dependent interband transitions of FLG\, for bilayer graphene\, trilayer (TLG) graphene and tetralayer graphene (4LG). We retrieve and reconstruct these characteristic complex optical conductivity resonances from the amplitude and phase of the scattered light\, which e.g. allow for the unambiguous assignment of previously undetected ABCB domains in 4LG.Coupling the (stacking-dependent) FLG with phonon polaritons in a hBN TLG heterostructure also leads to coupled polaritons (hyperbolic phonon plasmon polaritons). We explore how they allow for super-resolution imaging of subdiffraction-sized defects in graphene through the hBN cover layer via the so-called hyperlensing effect. Furthermore\, we show how resonators for polaritons in 2D materials like hBN can be easily fabricated and optically reconfigured using Phase-Change Materials. \n\n\n\n \n\n\n\n \n\n\n\nVenue: RUN Auditorium

SUMMARY:RTG Colloquium: Gabriele Kaminski Schierle & Clemens Kaminski
DESCRIPTION:Biological imaging at the nanoscale\n\n\n\nClemens F. Kaminski\, University of Cambridge \n\n\n\nThe advent of optical super‑resolution imaging together with the ability to label specific cellular components with fluorescent markers has ushered in a revolution in our mechanistic understanding of biological processes. In this presentation\, I will provide an overview of current methods used to obtain nanoscale insights into the molecular machinery that supports life at the subcellular level. I will present approaches for tracking protein interactions\, using single‑molecule localisation microscopy as well as indirect techniques such as fluorescence lifetime imaging microscopy. I will then discuss methods based on structured illumination microscopy\, which enable dynamic interrogation of cellular machinery including lysosomes and the endoplasmic reticulum. Finally\, I will offer an outlook on emerging trends and how machine learning is transforming our field. \n\n\n\nCoffee break & discussion \n\n\n\nBeyond Alzheimer’s: conserved lysosomal dyshomeostasis as a driver of synaptic dysfunction across neurodegenerative proteopathies\n\n\n\nGabriele S. Kaminski Schierle\, University of Cambridge \n\n\n\nWhile scientists know that in Alzheimer’s disease\, lysosomes (the cell’s “trash cans”) clump together and lose their acidity\, they didn’t know if this happens in all neurodegenerative diseases.This study found that this “trash can” breakdown actually happens across many diseases\, including ALS\, Parkinson’s\, and Frontotemporal Dementia. Instead of being spread out normally to clean the whole cell\, the lysosomes clump tightly around the cell’s centre.By tracking cell electricity and layout\, the researchers discovered that this clumping severely damages brain signalling. Because the lysosomes are stuck in the centre\, they can’t reach the distant outer branches of the brain cells to clear out old\, broken proteins. This causes waste to build up and shorts out communication between neurons.Ultimately\, this suggests that fixing where lysosomes sit and restoring their acidity could act as a single\, powerful treatment for multiple brain diseases. \n\n\n\nVenue: RUN Auditorium

SUMMARY:RTG Colloquium: Alice Kunin
DESCRIPTION:High-performance time-resolved photoemission experiments of quantum materials\n\n\n\nPrinceton University \n\n\n\nI will discuss our work coupling MHz\, kW light sources with momentum microscopy to enable efficient time- and angle-resolved photoemission (tr-ARPES) studies. I will first examine the dynamics of intra- and interlayer excitons in twisted van der Waals heterobilayers. I will then discuss our current work on a new spectrometer to probe ultrafast surface photochemistry in situ with the extension of tr-ARPES beyond ultrahigh vacuum towards more realistic chemical environments. \n\n\n\nVenue: RUN Auditorium
