Taking focusing to the extreme: Is there something new? - An intermediate report from a long journey
Gerd Leuchs, Max-Planck-Institute for the Science of Light, Germany

Focusing light from all directions in 3D may be an unusual scenario but it is required for a range of experiments from efficiently coupling a single photon to a single atom in free space to reaching the Schwinger limit for the electric field, at which the quantum vacuum will turn ... more

LIVE ONLINE PRESENTATION: Harnessing structured light for advanced optical trapping
Prof. Dr. Cornelia Denz, WWU Münster

Since the Nobel award for optical tweezers in 2018, the paramount potential of optical trapping of micro- and nanoparticles has become obvious. Nowadays, structured light fields, customized in its amplitude, phase or polarization, containing singularities or being tightly focused ... more

Probing halide perovskites by photoelectron spectroscopy – what have we learned by now?
Selina Olthof, Universität Köln

Research on novel semiconducting materials for application in optoelectronic devices has gained increasing interest in the past years. This is especially true for halide perovskites, which show extraordinary efficiencies when used as absorber material in solar cells. However, rat ... more

Mapping Orbital Information in the TEM
Stefan Löffler, University Service Centre for Transmission Electron Microscopy, TU Wien, Austria

Electronic states shape the world around us and are typically described in terms of orbitals. These orbitals as well as their complex interactions with each other and with external fields define material properties both on the atomic and on the macroscopic scale. Be it chemical b ... more

Sensing with Structured Beams
Martin Lavery, University of Glasgow

Structured beams are optical fields that are generated to have very specific spatially patterned phase and intensity profiles. There are a wide variety of these beams that interact with media and the environments in unique ways depending on their spatial profile. In this talk we ... more
