Anderson Localization of Ultracold Atoms in Laser Speckle Disorder

This lecture explores the experimental observation of 1D localization of ultra-cold atoms in correlated disorder produced by laser speckle, highlighting the discovery of an effective mobility edge that aligns with theoretical calculations. Learn about the challenges faced when comparing 3D experiments to theory and discover how researchers modified their experimental approach to release atoms with well-defined energies into disorder. Examine the breakthrough results that enabled direct measurements of the mobility edge with unprecedented accuracy and observe the patterns of localized wave-functions when atoms with narrow energy distribution are released below the mobility edge. Understand how these findings open new possibilities for testing landscape theoretical descriptions through precise disorder engineering, a goal that appears achievable in the near future.
