Local probing of two-dimensinonal superfluid gases in the BEC-BCS crossover — •Klaus Hueck, Keno Riechers, Wolf Weimer, Kai Morgener, Jonas Siegl, Niclas Luick, Thomas Lompe, and Henning Moritz — Institut für Laserphysik, Universität Hamburg, Luruper Chaussee 149, 22761 Hamburg
In this poster we present local measurements of the superfluid fraction of a strongly interacting two-dimensional gas of diatomic Li6 molecules. Using a high resolution imaging system, we perform a local measurement of the phase fluctuations on a single layer 2D gas. From this we extract the algebraic scaling exponent of the first order correlation function g(1)(r). This exponent is directly proportional to the superfluid density.
We furthermore report on our progress towards the creation of homogeneous two-dimensional Fermi gases in the BEC-BCS crossover.
