Since 1 July 2016, the DFG collaborative research center OSCAR, Open System Control of Atomic and photonic matter with Reservoirs, is up and running. Groups from U Bonn and TU Kaiserslautern are collaborating within this CRC. Our group contributes two projects.
Research area B: Control of quantum many-body systems by environments.
Our group contributes to this area by developing the theory for understanding the dynamics of Bose-Einstein condensates with complex interactions, like photon condensates investigated experimentally in Martin Weitz' group. The main theoretical tool is non-equilibrium Keldysh quantum field theory.
Research area C: Topological states in atomic and photonic systems.
The main focus lies on the development of basic tools and methods to create topological order in atomic and photonic matter as an alternative approach to control and protect quantum states. We investigate the topological stabilization of transport in Floquet-topological systems, where topological order is induced by time-periodic driving. Floquet-topological states are investigated experimentally in Dieter Meschede's group, using quantum walk techniques.
