Mixtures of ultracold fermionic atoms in low dimensions — •Armin Ridinger, Thomas Salez, Saptarishi Chaudhuri, Ulrich Eismann, David Wilkowski, Frédéric Chevy, and Christophe Salomon — Laboratoire Kastler Brossel, Ecole Normale Supérieure, Université Pierre et Marie-Curie-Paris 6, 24 rue Lhomond, CNRS, F-75231 Paris Cedex 05, France

We present the design of our new apparatus for creating cold mixtures of 40K and 6Li fermions with which we intend to study condensed matter physics phenomena. Our apparatus will allow us to simulate several Hamiltonians describing intereracting many-body fermionic systems in one, two and three dimensions. We report on the initial performances of our subsystems including a 2D MOT source of Potassium atoms, a Zeeman slowed Lithium beam, and a dual species magneto-optical trap. We are now working on the magnetic transport towards the science chamber where we intend to evaporate the mixture to quantum degeneracy in an optically plugged quadrupole trap. In this chamber with large optical access periodic potentials will be realized using optical lattices and a high resolution imaging system will be installed. We further report on the constuction of a solid-state laser source for Lithium in the one Watt power range suitable for laser cooling of Lithium.
