I spend most of my time thinking about how we can utilize cold atoms to learn about many-body physics, especially that which is relevant for condensed matter systems. Cold atom experiments have over the past few years established their ability to emulate strongly correlated models of interest from solid state physics. This has opened the door to study exotic, ill-understood states of matter (e.g., topological phases, spin liquids) and the transitions between them in a highly controlled, tunable, and clean environment. I am interested in the physics of such matter, as well as the questions of how to engineer it in cold atoms: firstly, how can one create exotic physics and secondly, how can one probe it's behavior?
I graduated as "Diplom-Physiker" from the Technical University in Munich in 2008, and received my Ph.D. from the University of Innsbruck in 2012. For my Ph.D. I worked in the groups of Peter Zoller in Innsbruck and Andrew Daley at the University of Pittsburgh. I joined Ana Maria Rey's group as PostDoc in 2013. My main interest is non-equilibrium many-body dynamics of ultracold atoms, molecules (in optical lattices) and ions. In particular the latter two interest me because of the possibility to realize novel many-body models with long-range interactions. Furthermore, I'm interested in numerical techniques with matrix product states/operators and like to adapt these to study dynamics under realistic experimental conditions, including effects of classical and quantum noise.

I received my B.S. from Nanjing University in China, and M.S. from the Institute of Theoretical Physics, Chinese Academy of Science. I joined Ana's group as a graduate student in the Fall of 2008. My research interests are the behavior of atoms in optical lattice potentials; for example, new phases and exotic fractal behavior of polarized fermions in bichromatic optical lattices. I am also interested in quantum optics issues, such as the interaction between atoms and a quantized laser field.
I am a graduate student at the University of Colorado Boulder. My current research interests involve ultracold gases of atoms and molecules, and especially the many-body physics of systems with long-range anisotropic dipole-dipole interactions; for example, the non-equilibrium dynamics of ultracold polar molecules and quantum magnetism in an optical lattice.
