Strongly Correlated Quantum Matter in Optical Lattices

Ultracold bosonic and fermionic quantum gases in optical lattices can be used as versatile model systems for the investigation of fundamental condensed matter physics hamiltonians. We report on two novel detection techniques, which have allowed us to reveal e.g. the in trap density profile of strongly correlated bosonic quantum gases in the lattice. Thereby we have been able to observe the formation of spatial shell structures in the density of the trapped atom cloud across the superfluid to Mott insulator transition. In addition we use quantum noise correlations in expanding bosonic and fermionic atom clouds released from the lattice to observe quantum statistical Hanbury-Brown and Twiss type hunching and antibunching of the atoms and show that this can be used to reveal the ordering of the particles in the lattice.
