Fermi acceleration of Anderson-localized atoms

This paper experimentally studies the expansion of a quantum gas of ultracold fermionic lithium atoms inside a disordered potential that changes over time. By tuning the disorder strength and rate of change, the authors observe different regimes of anomalous diffusion, from localization to superdiffusion. A key finding is the suppression of acceleration for sufficiently slow disorder dynamics, attributed to localization from matter-wave interference. Overall, this connects the phenomena of Anderson localization and Fermi acceleration in a tunable quantum system.
