• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas ; Experimental Condensed Matter Physics ; Theoretical Condensed Matter Physics
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 277625399

This research project concerns the physics of non-linear optical cavities placed into a small array. By placing single or few trapped atoms with a strong coupling to the cavity mode into one or both halves of the cavity, we will realize a two-site Bose-Hubbard model for light and we aim for studying interaction-controlled tunnelling of single photons and the generation of entanglement between atoms and/or photons under the influence of dissipation. Furthermore, will extend the studies of cavity-induced backaction of the emission characteristics of a single atom in a cavity to the more complex case of two-dimensional material and tailor the retardation of the backaction of the cavity field onto excitons.
