Degenerate mixtures of ultracold 40K-6Li Fermions in low dimensions — •Franz Sievers, Norman Kretzschmar, Diogo Fernandes, Frederic Chevy, and Christophe Salomon — Laboratoire Kastler Brossel, Paris
We present the design of our new apparatus for creating cold mixtures of 6Li and 40K Fermions with which we intend to study condensed matter physics phenomena. Our experimental setup will allow us to simulate several Hamiltonians describing interacting 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, a dual species magnetooptical trap and a magnetic transport from the MOT- to the science chamber. We are now working on the evaporative cooling of the mixture in an optically plugged quadrupole trap. In the science chamber with large optical access periodic potentials will be realized using optical lattices and a high resolution imaging system will be installed.
