    "abstract": "We show that ballistic transport of optically excited atoms in an atomic\nvapor provides a nonlocal nonlinearity which stabilizes the propagation of\nvortex beams and higher order modes in the presence of a self-focusing\nnonlinearity. Numerical experiments demonstrate stable propagation of lowest\nand higher order vortices over a hundred diffraction lengths, before\ndissipation leads to decay of these structures.",
