From CIQC PI David Weld’s research group:
By throwing atoms and watching them come back to the starting point, experimentalists have now observed for the first time a dynamical feature of disordered quantum matter called the “quantum boomerang effect.” More than 60 years ago Phil Anderson pointed out that quantum mechanical effects of disorder in a material can localize electrons– that is, prevent them from leaving a small neighborhood, thereby turning a metal into an insulator. Only recently, theorists predicted that if a particle is launched in any direction in an Anderson...
