Molecular Diffusion, Reaction and Self-Assembly on 2D Materials
Dr. Marco Sacchi, University of Surrey

In the last decade, the surface science community has focused much of its effort on understanding the surface property of 2D materials, in particular graphene. From the technological standpoint, 2D materials have been employed in sensors, optical and electronic devices, membranes ... more

Resonant (laser) excitation of the Thorium-229 nucleus
Prof. Thorsten Schumm, Vienna University of Technology

Among all known isotopes, Thorium-229 has the lowest nuclear excited state, only 8.4 eV above the ground state. This so-called “isomer” is accessible to VUV laser excitation and a plethora of applications at the interface of atomic and nuclear physics have been proposed, inc ... more

Remodeling Feynman diagrams with chirality flow
Malin Sjödahl, Lund University

Since some 70 years, the standard method for calculating probabilities of particle scattering in collider experiments is to use Feynman diagrams which associate factors with interaction vertices and propagators. In this talk I will explore how standard Feynman rules can be signif ... more

Probing dynamical nonlinearities in a Floquet-Hubbard chain
Dr. Denitsa R. Baykusheva, ISTA Wien

Intense ultrashort off-resonant fields can hybridize with material excitations, giving rise to interesting light-driven phenomena such as transient superconducting-like phases, charge ordering, and excitonic condensation. A particularly intriguing platform for such studies are lo ... more

Nanoscale Cross-sectional Extreme-UV imaging
Prof. Dr. Gerhard G. Paulus, FSU Jena & Helmholtz Institut

I will discuss nanoscale imaging in the extreme ultraviolet (XUV) spectral region using high-harmonics produced by femtosecond laser radiation. The imaging method to be discussed is the XUV incarnation of optical coherence tomography (OCT), which, in turn, was invented in Austri ... more

Spectrally selective metasurfaces for spatially encoded light-matter coupling
Dr. Andreas Tittl, Group Leader Functional Nanophotonics, Chair in Hybrid Nanosystems, Nanoinstitute Munich, Ludwig-Maximilians-Universität München

Photonic bound states in the continuum (BICs) have enabled a new class of spectrally selective metasurfaces supporting ultrasharp resonances, enabling breakthroughs in higher-harmonic generation, strong light-matter coupling, biodetection, and lasing. However, many implementation ... more

Optical frequency comb absorption spectroscopy for laboratory astrophysics
Lucile Rutkovski, PhD, CNRS, Institut de Physique de Rennes, France

Laboratory data is necessary to interpret observations from Earth and space telescopes, and to validate the chemical network models of the interstellar medium and planetary atmospheres. In particular, spectroscopic data about the many molecular species involved in the various ext ... more

Metaoptics for Ultrafast Light
Dr. Marcus Ossiander, Institut für Experimentalphysik - Graz University of Technology

Vorstellung des Habilitationsvorhabens: My habilitation will delineate how we track and steer electron dynamics in solid state systems on the sub-femtosecond scale using few-cycle and extreme-ultraviolet (EUV) light pulses and how metasurfaces revolutionize their creation, man ... more

Strong-interacting Quark Matter in Neutron Stars
PD Dr. Bernd-Jochen Schaefer, Justus-Liebig-Universität Giessen, Institut für Theoretische Physik

The discovery and observation of gravitational waves from a binary neutron star inspiral have ushered in a new era of multi-messenger astrophysics. With the steadily increasing number of events and rising accuracy, many properties of neutron stars can now be measured with gre ... more

Correlations and geometric frustration – a happy marriage?
Dr. Thomas Schäfer, Max Planck Institut für Festkörperforschung, Stuttgart

Quantum materials in which the interaction effects of electrons cannot be neglected exhibit fascinating examples of contemporary condensed matter physics. Thrilling instances include the celebrated cuprates, organic charge-transfer salts, and moiré transition metal dichalcogenid ... more
