Biography

Before coming to Cambridge, I worked as a Senior Scientist/Group Leader in the Quantum Optics group at the Ludwig-Maximilians Universität in Munich. Before that, I did a PhD at the Johannes-Gutenberg Universität in Mainz supervised by Prof. Immanuel Bloch and read physics at the Universität Kaiserslautern.

Research

I am interested many-body phenomena at the interface between quantum optics and solid state physics.

We study this physics using ultracold atoms, that is Bose-Einstein condensates and degenerate Fermi gases, which we load into optical lattices. These periodic optical potentials play the role of the electrostatic potential felt by electrons in a conventional solid. Thereby, we effectively build a quantum simulator for condensed matter physics, where we can study many-body physics in a very clean and precisely controlled system and have all the tools from quantum optics at our disposal.
