The long-lived excitations relax through correlated angular dynamics involving \"lock-step\" angular displacements along the Fermi surface occurring in collinear two-particle collisions, a surprising behavior that is unique to 2D systems. We develop a microscopic picture of the non-Brownian random walk, describing the angular dynamics as anomalous diffusion (\"superdiffusion\") on the Fermi surface.
