Abstract

Using the Non-linear Schrôdinger Equation, we have found a new mechanism for the generation of vortices in a superfluid. This mechanism could be relevant for explaining the experimental creation of vortices by vibrations. This follows from the break-up of dark solitons in more than 1D, which are linearly unstable, as shown by Kusnetsov and Turitsyn, Z. Èksp. Teor. Fit., 94 (1988) 119 (Sov Phys. JETP, 67 (1988) 1583).
