The interplay of local perturbations and interactions is key for understanding quantum many-body systems. We study lithium Fermi gases in time-dependent disorder, using speckle potentials with quenches or finite correlation times.
We find the pair structure along the BEC-BCS crossover to govern macroscopic quantum responses. For noninteracting gases, we find the competition of Anderson localization and Fermi acceleration to dominate the diffusion.
