An Experiment on Quantum-Degenerate Fermi-Bose Mixtures in 3D Optical Lattices — •Silke Ospelkaus-Schwarzer, Christian Ospelkaus, Ralf Dinter, Jürgen Fuchs, Marlon Nakat, Klaus Sengstock, and Kai Bongs — Institut für Laser-Physik, Universität Hamburg

We present an experiment on a quantum-degenerate mixture of Fermionic ⁴⁰K and Bosonic ⁸⁷Rb atoms which is currently being set up in Hamburg. The apparatus is based on a two-species 2D-/3D-MOT setup and an optimized Ioffe-type magnetic trap. Our setup is designed for experiments in deep three-dimensional optical lattices and promise to be a versatile model system for solid state theories. Projected experiments cover single-particle and collective excitations, fermion correlations and investigations on the possibility of observing a BCS-type phase transition in a 3D-optical lattice. We present first experimental results and discuss the planned experiments.
