Ultracold atoms in optical lattices have proven to be a powerful tool for investigating quantum many body systems. Recent experiments have demonstrated the power of single-site resolved detection in optical lattices for the study of strongly correlated bosonic many body systems. In our experiment we plan to apply similar techniques to fermionic systems.

We are using mixtures of Li-6 and Li-7 atoms to achieve a degenerate bosonic or fermionic many body system trapped in a 3D optical lattice. With a high resolution imaging system, we will be able to resolve single sites in a 2D plane of the lattice and image single atoms. Superimposing an additional small-scale pinning lattice onto the larger-scale physics lattice in order to freeze out the distribution of atoms during imaging, we separate the detector from the physical system under study. This will allow for the investigation of different lattice geometries with single atom sensitivity.

We present the current status of our experimental realization and a method for in-situ thermometry in magnetic traps.
