Preparation and characterization of cold fermionic gases in optical lattices — •Daniel Greif, Thomas Uehlinger, Leticia Tarruell, Gregor Jotzu, and Tilman Esslinger — Institute for Quantum Electronics, ETH Zurich, Switzerland

Ultracold atoms in optical lattices are an almost ideal realization of the celebrated Hubbard Hamiltonian, which is a central model in strongly correlated condensed matter systems. The recent advance in control of fermionic quantum gases makes these systems a promising candidate to study the low temperature regime. This requires both development of sensitive probes on magnetic correlations and novel schemes for preparation of low entropy states in the lattice. We report on measurements of nearest-neighbor correlations, which can be used to detect local spin ordering, and recent progress on preparation of cold fermionic gases in the lattice.
