Quantum Simulation with Cold Atoms and Trapped Photons

Ariel Sommer

Post-Doctoral Fellow
University of Chicago

The complexity of quantum many-body problems has inspired experiments on artificial quantum materials that realize simple and well characterized models of condensed matter. Measurements of phase transitions and dynamics in cold atomic gases in particular have yielded valuable benchmarks on the physics underlying diverse materials, ranging from superfluids and superconductors to neutron stars. Recently, artificial quantum systems built from photons rather than atoms have revealed new possibilities in quantum simulation. I will describe our implementation of an effective magnetic field for photons trapped in an optical resonator, resulting in photonic Landau levels. Surprisingly, the optical resonator also enables us to impose a singularity of spatial curvature, allowing us to make the first observations of effects predicted for quantum Hall systems in curved space. We have implemented effective photon-photon interactions mediated by Rydberg atoms, which, in combination with effective magnetic fields, will enable future work on photonic fractional quantum Hall states and anyon excitations.
