Objective
In this project, we will investigate the many-body physics of interacting ultracold atoms in presence of strong gauge fields. The practical implementation will use Ytterbium atoms in optical lattices. We will use two atoms in two internal states- the ground state and a long-lived excited state- trapped in suitably designed state-dependent lattice potentials. Coherent coupling between the two states will be used to ``write'' a spatially-dependent phase on the atomic wavefunction, which under suitable conditions will mimic the Aharonov-Bohm phase accumulated by charged particles moving in a gauge field. Using this technique, we will study the behavior of interacting bosonic and fermionic quantum gases in such artificial gauge potentials for different lattice geometries. We will look for strongly correlated states analogous to those observed for 2D electrons experiencing the fractional quantum Hall effect, and study the unusual behavior of their elementary excitations (``anyons''). These novel quantum phases will be primarily characterized using high-sensitivity imaging with single-site resolution, enabling spatially-resolved measurements of the spatial distribution and of its correlation functions. The project will first investigate the simpler case of an Abelian gauge potentials for bosons and fermions, then move to the more complex case of a non-Abelian $SU(2)$ gauge field using two-component fermions. The resulting system can be seen as a laboratory playground to study interacting quantum matter (bosonic or fermionic) coupled to well-defined gauge fields, a situation encountered in many domains of Physics, from high-energies to condensed matter.
