Ultracold Fermi and Bose gases in exotic optical lattices. — •Mikhail Baranov1, Hans-Ulrich Everts1, Henning Fehrmann1, Luis Santos1, Ignacio Cirac2,3, and Maciek Lewenstein1,3 — 1Institüt für Theoretische Physik, Universität Hannover, 30167 Hannover, Germany — 2Max Plank Institüt für Quantenoptic, 85748 Garching, Germany — 3Institut de Ciéncies Fotóniques, Barcelona 08034, Spain
We study the phase diagram of ultracold quantum degenerate Fermi and Bose gases and thier mixtures in frustrated optical lattices, i.e. Kagome lattice and its trimerized modification. Placed in such a lattice, quantum gases demonstrate very reach phase diagrams, and can be used as a tool for modelling the behaviour of quantum fructrated antiferromagnets.
