The Kondo Lattice Model (KLM) is one of the canonical models used to study strongly correlated electron systems. In this talk I will describe our ideas on how to implement the KLM with ultra cold atoms. Two different implementations will be discussed. One specific for alkaline-earth atoms which uses two long-lived electronic levels and the other, more suitable for alkali atoms, which uses the control of multi-band superlattices. Using a mean field formulation I will discuss a possible fermionic KLM phase diagram which includes magnetic, heavy fermion and Kondo insulator phases as well the generalization of this phase diagram to bosonic systems. Keeping in mind the harmonic trapping potential present in cold atom experiments, I will discuss ways of probing and detecting the various phases.

Superfluidity and Dimerization in a Multilayered System of Fermionic Polar Molecules
Abstract: Ultra-cold gases of polar molecules offer a promising new
palette for realizing exotic many-body states and for engineering
interactions for quantum information processing applications. Recent
experimental progress towards trapping and cooling polar molecules
have brought these exciting possibilities closer to realization. A
common difficulty facing future experiments, is that unstructured
clouds of polar molecules are unstable towards few-body losses.
However, one can avoid this instability by confining dipoles into
two-dimensional layers. Motivated by these considerations, I will
discuss recent progress towards understanding superfluidity and
phase-transitions in a layered system of fermionic polar molecules.
Ana Maria Rey received her Ph.D. from University of Maryland in 2004.
Her research on ultra-cold bosonic atoms in optical lattices was done in a combined program between the University of Maryland and NIST, Gaithersburg. For this work, she received the 2005 DAMOP Thesis Prize. She followed her Ph.D. studies with a postdoctoral fellowship at the Institute for Theoretical Atomic, Molecular, and Optical Physics at the Harvard-Smithsonian Center for Astrophysics. In the fall of 2008 she became an associate fellow of JILA and a research assistant professor in the Physics department at the University of Colorado at Boulder.
