Short bio

Since the end of January 2020, I am a Lecturer in Mathematical Physics in the School of Mathematics at Cardiff University. Before that I was a postdoc working on the GAPS project of David Pérez García. Even earlier I was a Marie Skłodowska-Curie fellow funded by the European Union. This allowed me two work two years at UC Davis in the group of Bruno Nachtergaele, after which I returned to Germany to work on the final year of this project in the group of Barbara Terhal (now also at TU Delft). You can find my full CV here.

  • Two papers accepted

    Two of my papers have been accepted for publication in Commun. Math. Phys. and J. Phys. A., respectively. »

  • Moved to Madrid

    On November 5 I started my new position at the Universidad Complutense de Madrid. I will be working in a senior postdoc role in the GAPS of David Pérez García. See the updated contact page on how to find me there! »

  • Stability of superselection sectors

    Our paper On the stability of charges in infinite quantum spin systems has just appeared on the arXiv. In it we prove that the superselection structure describing the anyons in abelian versions of Kitaev's quantum double model is stable against perturbations of the dynamics. »

  • AHP Prize 2016 for our paper

    Our paper on Haag-Ruelle scattering in quantum spin systems has been awarded the AHP Prize 2016 for the most remarkable paper in the journal! Many thanks in particular to my co-authors Sven Bachmann and Wojciech Dybalski for working together on this interesting project. »

  • Book on quantum spin systems published

    LNP book cover My book, based on lecture notes for a course I taught at Leibniz University Hannover, has been published in Springer's Lecture Notes in Physics series. It gives an introduction to the mathematics of quantum spins with infinitely many sites, accessible to students with a basic background in mathematics or theoretical physics. »

  • Jones index, data hiding and total quantum dimension

    My paper with Leander Fiedler and Tobias Osborne on the total quantum dimension is available on the arXiv. »

  • Ground states of abelian quantum double models

    We have uploaded a new paper, where we classify all ground states of Kitaev's quantum double model for abelian groups. »

  • Haag duality in Kitaev's quantum double models

    Our paper on Haag duality in quantum double models has been published in Reviews in Mathematical Physics. Read on for a summary of our main results. »

  • New website uploaded

    The website has been updated and redesigned, to reflect my move to UC Davis. »

  • Marie Sklodowska-Curie project started

    I have started working on the `Operator-algebraic Approach to Topological Phases’ (OATP) project funded by the European Union. This project will run for three years. See here for more details. »
