Abstract
The form and stability of quantum vortices in Bose-Einstein condensates with attractive atomic interactions is elucidated. They appear as ring bright solitons, and are a generalization of the Townes soliton to nonzero winding number m. An in?nite sequence of radially excited stationary states appear for eachvalue of m, whichare characterized byconcentric matter-wave rings separated by nodes, in contrast to repulsive condensates, where no such set of states exists. It is shown that robustly stable as well as unstable regimes may be achieved in con?ned geometries, thereby suggestingthatvortices can be observed in experiments on attractive condensates in two dimensions.Citation
