Description
We simulate the preparation of a superposition of vortex states in a Bose-Einstein condensate trapped in a ring geometry. It has been proposed that a vortex-antivortex superposition can be used as an inertial sensor, e.g. to measure rotations, or as a magnetic field sensors [1,2]. In both cases, the external influence causes a precession of the BEC standing wave, which can be measured experimentally. In this talk I will show how computer-generated holography [3] can be used for the efficient preparation of these states, and I will demonstrate their stability by simulating their subsequent evolution.
