Strongly interacting Fermi gases at the single atom level

The Lithium III Lab aims at exploring the behavior of strongly interacting Fermi gases using Lithium 6. This new generation experiment is designed to allow for high resolution shaping of arbitrary potentials and detection of single atoms. These tools offer a microscopic perspective for the study of the BEC-BCS crossover in 3D, 2D as well as topological states of matter.
