Submission summary

The study of Many-Body Localization (MBL) in a highly controlled environment is at the heart of this project. MBL is the inhibition of transport in a many-body interacting system in the presence of a strong disorder. It is the analog for interacting particles of Anderson localization in a single-particle disordered system. The project focuses on open problems for MBL, such as the nature of the MBL-delocalized transition and the expected discovery of a many-body mobility edge. We plan to use a kicked rotor with interacting ultracold Potassium atoms. This system is ideal to finely probe in situ localization effects with high-end tools such as Coherent Back/Forward Scattering processes. It also easily allows the on-demand synthesis of arbitrary dimensions and symmetry properties. To keep a constant atomic density, the ultracold gas will be trapped in a torus shape, thus realizing a kicked rotor with periodic boundary conditions.
