The TRR 227 kindly invites you to the Physics Colloquium of the PGzB* at the Magnus-Haus.
Speaker: Prof. Dr. Peter Baum, Universität Konstanz
Title: Seeing atoms and electrons in space and time
The fundamental reason behind almost any light-matter interaction are atomic and electronic motion in space and time. In order to provide a movie-like access to such dynamics, we unify electron microscopy with attosecond and femtosecond laser technology. In this way, we combine the awesome spatial resolution of modern electron beams with the spectacular time resolution that is offered by the cycle period of light.
Selected results will be reported on the electric fields within metamaterials, the Einstein-de-Haas effect on atomic dimensions, the reaction path of phase transitions and the formation of free-electron qubit states. Many breakthroughs in science and technology have been achieved by disruptive imaging techniques, and our 4D electron microscopy may play this role for light-matter interaction on atomic dimensions.

About Berlin Physics Colloquium
The Berlin Physics Colloquium in the Magnus House was initiated in 1998 by the Physical Society of Berlin. The colloquium is organised jointly by the Freie Universität Berlin, the Humboldt University of Berlin, the Technical University of Berlin and the University of Potsdam with the support of the Wilhelm and Else Heraeus Foundation. It takes place on the first or second Thursday of every month, except in March, August and September.
