Abstract

By performing numerical calculations of the quasi-two-dimensional GP equation, the dynamical generation and evolution of vortex excitations under collision between a superflowing ring-shaped BEC and a centered static BEC are investigated. We study the collision between a superflowing ring-shaped BEC and a static centered BEC. Symmetrically positioned singly quantized vortices can be created and their time evolution mainly depends on the atomic interactions.
