The Fritz Haber Institute (FHI) in Berlin-Dahlem is one of the oldest and most renowned research institutes within the Max Planck Society (MPG), Germany's most successful scientific organization. At the FHI, researchers from all over the world are engaged in basic research in the field of chemical physics at interfaces and surfaces, catalysis research and molecular physics.


The Structural & Electronic Surface Dynamics group at the Fritz Haber Institute is offering a

Postdoc Position: Probing ultrafast dynamical topology in 2D materials using multidimensional photoemission spectroscopy

The Structural & Electronic Surface Dynamics group at the Fritz Haber Institute (https://pc.fhi-berlin.mpg.de/sesd/) is offering a postdoctoral position in experimental condensed matter physics. The group is investigating the electronic and atomic structure of solids and heterostructures in out-of-equilibrium conditions. We develop and use ultrafast techniques providing movies of the electronic and atomic structure in solids and nanostructures. From these time-resolved measurements, we infer information on coupling and correlation effects of electrons and atomic motion. The Fritz Haber Institute and the Department of Physical Chemistry offer an excellent and interdisciplinary environment for top-of-the-line research. The group operates a world-leading high-repetition rate extreme ultraviolet (XUV) time- and angle-resolved photoelectron spectroscopy (trARPES) setup including a momentum microscope.

Topics of the research:

The scope of the offered position is the investigation of the dynamical topological properties of photoexcited 2D materials and their heterostructures. The successful applicant will operate the in-house high-repetition rate XUV trARPES setup to perform state-of-the-art experiments to investigate how ultrashort laser pulses can be used to tailor the topological properties of matter on ultrafast timescales. In order to achieve this goal, the successful applicant will also participate to the installation of a new high-repetition rate optical parametric amplifier in order to produce intense mid-infrared pump pulses, that will be coupled to the existing trARPES setup. The research is part of the EU-funded project OPTOlogic (https://cordis.europa.eu/project/id/899794).

The PostDoc position is initially limited to 2 years.
