Nonlocal Stabilization of Nonlinear Beams in a Self-focusing Atomic Vapor

Skupin, Stephan; Saffman, Mark; Krolikowski, Wieslaw


We show that ballistic transport of optically excited atoms in an atomic vapor provides a nonlocal nonlinearity which stabilizes the propagation of vortex beams and higher order modes in the presence of a self-focusing nonlinearity. Numerical experiments
