Building a Shaken Lattice of Ultracold Lithium Atoms

ORAL

Abstract

The shaken lattice technique has provided new ways of controlling tunneling coefficients, manipulating band structures, enhancing interactions, exhibiting non-trivial topology, and to the discovery of interesting symmetry breaking phases. For ultracold fermions in particular, this offers the possibility of quantum simulation for a wide range of Hamiltonians relevant to solid state and materials physics. We are currently building an optical lattice that can be shaken by acousto-optical modulation and loaded with ultracold lithium gas. We shall introduce lattice setup and initial tests, as well as the efforts on acquiring a precise control on its modulation. We will also discuss planned experiments involving tunable Fermi surface shape.
