In February 2015, I started a research group at the University of Luxembourg as an Associate Professor of Physics. My position is funded by the ATTRACT program of the Fonds National de la Recherche. Within this project about modern mesoscopic systems, my group investigates topological insulators, one-dimensional quantum systems, as well as nanomechanical systems in the quantum regime.
Major research collaborations
I started studying physics in the fall term of 1999 at the University of Freiburg (Germany)
my diploma in 2004, specializing in mathematics and the physics of complex systems. I wrote my
thesis in the department of theoretical condensed matter physics of Prof. Dr. H Grabert
at the University of Freiburg under supervision of Prof. Dr. Andrei Komnik.
Afterwards, I remained in the same group and started working on my PhD thesis. During the PhD phase, I spent six months at the Imperial College London (UK) in the group of the late Prof. A. Gogolin. After returning to Freiburg, I finished my PhD thesis in November 2007.
Then, I started a postdoc position at the University of Basel in the group of Prof. Dr. C. Bruder. My primary focus shifted to the investigation of the properties of nanoelectromechanical systems. This work is done in collaboration with Prof. Dr. B. Trauzettel from the University of Würzburg.
In May 2009, I started a postdoc position at Yale University in New Haven (CT), USA in the group of Prof. L. Glazman. This research was sponsored by the Swiss National Science Foundation and involved the investation of strongly correlated one-dimensional systems. We extended the Luttinger liquid theory by taking into account the band curvature. In particular, we focused on spinful fermionic systems and the fate of the spin-charge separation. More recently, in collaboration with L. Glazman and A. Imambekov, we reviewed to physics of interacting 1D systems beyond the limits of the Luttinger liquid theory in an article in Reviews of Modern Physics.
In February 2012, I returned to the University of Basel as a junior research group leader in the ambizione program, funded by the Swiss National Science Foundation. Within this project, we investigated quantum effects in nanomechanical and optomechamical systems. In addition, research on 1D systems continued, especially on helical liquids which are the edge states of two-dimensional topological insulators. We also investigated properties of Majorana bound states in solid-state systems.
