"Time-resolved optical spectroscopy enables the study of the dynamical properties of charge carrier and spin states in solids on very short femtosecond time scales. This includes, for example, the quantum mechanical evolution of optically excited electron states, as well as their decoherence and relaxation processes. Of particular interest are the interactions between different fundamental quasiparticles in the solid state, such as excitons, magnons, plasmons, and phonons. To this end, we are investigating novel hybrid structures that combine different materials: Semiconductors with excellent optical properties, ferromagnetic materials with strong exchange interaction, and metallic nanostructures for localized confinement of electromagnetic fields. To experimentally investigate these phenomena, we use various high-precision optical measurement methods such as ultrafast excitation-interrogation experiments (pump-probe), or time-dependent four-wave mixing in combination with magnetic fields and polarization-dependent excitation and detection. In particular, we are working on the following topics and their further development:
- Photon echoes in semiconductor nanostructures.
- Spin interaction in hybrid ferromagnet-semiconductor nanostructures
- Plasmonic systems in combination with magnetic materials
- Excitation and control of spin waves in ferromagnetic structures by fs laser pulses".

Location & approach
The campus of the Technical University of Dortmund is located near the freeway junction Dortmund West, where the Sauerland line A45 crosses the Ruhr expressway B1/A40. The Dortmund-Eichlinghofen exit on the A45 leads to the South Campus, the Dortmund-Dorstfeld exit on the A40 leads to the North Campus. The university is signposted at both exits.
The "Dortmund Universität" S-Bahn station is located directly on the North Campus. From there, the S-Bahn line S1 runs every 20 or 30 minutes to Dortmund main station and in the opposite direction to Düsseldorf main station via Bochum, Essen and Duisburg. In addition, the university can be reached by bus lines 445, 447 and 462. Timetable information can be found on the homepage of the Rhine-Ruhr transport association, and DSW21 also offer an interactive route network map.
One of the landmarks of the TU Dortmund is the H-Bahn. Line 1 runs every 10 minutes between Dortmund Eichlinghofen and the Technology Center via Campus South and Dortmund University S, while Line 2 commutes every 5 minutes between Campus North and Campus South. It covers this distance in two minutes.
From Dortmund Airport, it takes just over 20 minutes to get to Dortmund Central Station by AirportExpress and from there to the university by S-Bahn. A wider range of international flight connections is offered by Düsseldorf Airport, about 60 kilometers away, which can be reached directly by S-Bahn from the university's train station.
The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent "Technologiepark".Zum Lageplan
