Welcome to the research group Reiter

Our research group studies the theoretical modelling of dynamics on ultra short time and length scales. An introduction to our research can be found here. My CV and further information can be found in the research portal of the WWU Münster.

We have several collaborations within the WWU Münster, in particular with the AG Kuhn and the AG Bratschitsch, and with other theoretical and experimental groups from all over the world, e.g., with Martin Axt from Bayreuth, Germany, Ortwin Hess from London, UK, Jacek Kasprzak from Grenoble, France and Pawel Machnikowski from Wroclaw, Poland.

We are always happy to talk about our work. If you are interested in a bachelor or master thesis in our group, please contact us via E-Mail and make an appointment.

New publication in 'Physical Review B' discusses the sensitivity of four wave mixing signals with respect to the pulse area

© Daniel Wigger

Four wave mixing spectroscopy it a sophisticated method to explore quantum systems with a focus on couplings and coherences. We have been studying the four wave mixing signals of a single quantum dots (see also: https://doi.org/10.1364/OPTICA.3.000377). In this publication we now show that the four wave mixing signals depend sensibly on the properties of the exciting laser pulses. We conclude that is important to know precisely the strength of the exciting pulses, because the shape of the signals may differ significantly for different pulse strengths.

This work is a collaboration with the experimental group of Jacek Kasprzak from Grenoble.

New publication in 'Acta Physica Polonica A' about the optical signals of carrier capture processes

© Frank Lengers

When electrons in a semiconductor impinge on a localized potential, carrier can be captured into the potential mediated by the interaction with phonons. We were able to show that such a capture process happens locally, i.e., only carriers in the vicinity of the potential can be captured (read more about this here). In this publication we now show that the local nature of the capture process is also reflected in optical signals by looking at time resolved pump probe signals.

Andreas Völker finishes his Bachelor thesis

© Andreas Völker

During the past month Andreas Völker worked on his Bachelor thesis in our group. Now he has handed in his theses about Theoretical analysis of bound states in 2D materials and presented his work in a talk. In his thesis he showed by numerically solving the Schrödinger equation, that in potential wells, which might appear in monolayers, there are numerous bound states. He further analysed the corresponding optical transitions. Congratulations to Andreas and we wish him all the best for his Master studies!
