Towards Ultracold Fermions in Optical Kagome Lattices
POSTER
Abstract
We report our progress towards incorporating 40K, a fermionic isotope of potassium, into our optical kagome lattice experiment. Due to the highly frustrated nature of the kagome lattice, there is a macroscopic degeneracy in the s-orbital manifold, which results in strong enhancement of interaction effect. This platform is therefore ideal for studying strongly interacting manybody phenomena, such as superfluidity and flat band ferromagnetism. We describe the necessary instrument upgrades on the previous 87Rb machine, as well as several additional capabilities planned for the new experiment.
