The Wilhelm and Else Heraeus Foundation has generously approved a workshop on quantum electron optics, which we are organizing together with Profs. Ady Arie (Tel Aviv) and Nahid Talebi (Kiel). This workshop will thus become the 770th WE Heraeus seminar to be held in Israel in June 2022. Application ...

Ang Li has received the Best Student Paper Award at the 22th International Conference on Ultrafast Phenomena, which took place as a virtual event from November 16th to 19th 2020. The talk was about our new data on quantum path interference of photoemission from metal nanotips in two-color laser fiel...

In dielectric laser acceleration, nanostructures etched into silicon are used to convert free-space ultrashort laser pulses to accelerate particles. This current approach, namely, illuminating the structure with a laser directed nearly horizontally to the substrate, is experimentally challenging and...

A defense under very special circumstances, via Zoom -- everything went well, in terms of content anyway, and technically there were only two minimal hiccups. Constanze Gerner defended her dissertation with great success in a very lively defense despite the purely virtual meeting. The Zoom reception...

Our early student Tamara Pröbster was awarded 1st prize in the field of physics in the Bavarian state competition Jugend forscht. In her research project at our chair, Tamara investigated how ultrafast light-induced electron emission from graphene can be decoupled into different processes - accordin...

When two-color femtosecond laser pulses interact with matter, electrons can be emitted through various excitation pathways involving different combinations of photons from the individual colors. Quantum interference between these pathways gives rise to a strong oscillation of the photoemitted electr...

In our most recent publication in Applied Physics Letters we demonstrate the splitting of an electron beam in the energy range from 200 to 1700eV using auto-ponderomotive electron optics (see also preceding news flash here). The ponderomotive potential is shaped in such a way that the minimum at th...

The control of electron and ion beams are of great importance for many areas of research and technology. Both are used, for example, in electron microscopes but also in medical patient treatment. In our latest publication in Nature Communications, we report on the development of auto- ponderomotive ...

Strict anti-virus propagation measures have again forced an apparently rather boring defense, but in terms of content this has not detracted from the matter: Norbert Schönenberger has defended his dissertation with great success. Congratulations!

Our long-time partner and frequent and especially welcome guest in Erlangen Mark Stockman PhD DSc, Regents Professor of Physics and Director of the Center for Nano Optics at Georgia State University, died on November 11th at the age of 73 years. Professor Stockman left his mark on entire fields of p...
