Focus of work
The main goal of our group is to control the magnetic and electronic properities of solids on the shortest possible timescale. In particular, we use femtosecond laser pulses to achieve ultrafast control of the spin and charge degrees of freedom without energy dissipation i.e. by exploiting coherent effects. The main experimental methods are:
- time-resolved optical and magneto-optical spectroscopy
- spin- and time-resolved photoelectron spectroscopy
The main material systems under study are:
- Spin-textured and magnetically ordered two-dimensional electronic systems: 2D semiconductors, 2D antiferromagnets, topological insulators, quantum wells, ...
- Hybrid molecular interfaces with non-trivial spin properties (molecular spinterfaces).
Our research is funded by the Deutsche Forschungsgemeinschaft (DFG) and by the European Research Council (ERC).

Thuesday, 08.00 a.m. – 12.00 a.m.: Einführung in die Festkörperphysik
My scientific education started at Università degli Studi di Pavia (Italy) and National University of Ireland Maynooth (Ireland) in the field of quantum information and quantum computation theory, exploring the use of spin as a quantum mechanical two-level system to store and manipulate quantum information. I then moved into the field of experimental solid-state physics and started a PhD at the Johannes Gutenberg University in Mainz (Germany), under the guidance of one of the world-leading experts in photoemission electron microscopy: Prof. Gerd Schönhense. During the PhD I established photoemission electron microscopy as a tool for the investigation of optical near fields, opening the way for the implementation of this experimental method in the field of plasmonics. In 2004, after my PhD, I moved to University od Kaiserslautern (Germany) for a Postdoctoral position in the group of Prof. Martin Aeschlimann, a world-leading expert in time-resolved photoemission methods with femtosecond time-resolution. Combining my previous experience on photoemission with the knowledge on time-resolved methods I moved in the novel field of femto-magnetism. In 2008 I received a permanent position (as an assistant professor, in German “akademischer Rat”) at the University of Kaiserslautern, where I also obtained my Habilitation in Experimental Physics in 2012.
During my Habilitation I have opened a new research direction in femtosecond magnetism - femtosecond molecular spintronics, and secured funding in different German and European funding schemes. In 2015 I was elected as German representative (MC member) for the COST Action CA15128: Molecular Spintronics (MOLSPIN). In October 2016 I was appointed as full professor (W3) at TU Dortmund University.

Location & approach
The campus of TU Dortmund University is located close to interstate junction Dortmund West, where the Sauerlandlinie A 45 (Frankfurt-Dortmund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is "Dortmund-Eichlinghofen" (closer to Campus Süd), and from B 1 / A 40 "Dortmund-Dorstfeld" (closer to Campus Nord). Signs for the university are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dortmund.
To get from Campus Nord to Campus Süd by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at Campus Nord and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.
TU Dortmund University has its own train station ("Dortmund Universität"). From there, suburban trains (S-Bahn) leave for Dortmund main station ("Dortmund Hauptbahnhof") and Düsseldorf main station via the "Düsseldorf Airport Train Station" (take S-Bahn number 1, which leaves every 20 or 30 minutes). The university is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.
You can also take the bus or subway train from Dortmund city to the university: From Dortmund main station, you can take any train bound for the Station "Stadtgarten", usually lines U41, U45, U 47 and U49. At "Stadtgarten" you switch trains and get on line U42 towards "Hombruch". Look out for the Station "An der Palmweide". From the bus stop just across the road, busses bound for TU Dortmund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dortmund main station to the stop "Dortmund Kampstraße". From there, take U43 or U44 to the stop "Dortmund Wittener Straße". Switch to bus line 447 and get off at "Dortmund Universität S".
The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.
The H-Bahn is one of the hallmarks of TU Dortmund University. There are two stations on Campus Nord. One ("Dortmund Universität S") is directly located at the suburban train stop, which connects the university directly with the city of Dortmund and the rest of the Ruhr Area. Also from this station, there are connections to the "Technologiepark" and (via Campus Süd) Eichlinghofen. The other station is located at the dining hall at Campus Nord and offers a direct connection to Campus Süd every five minutes.
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
