Abstract

We show that stable Skyrmions exist in two-component atomic Bose-Einstein condensates, in the regime of phase separation. Using full three-dimensional simulations we find the stable Skyrmions with topological charges Q = 1 and 2, and compute their properties. With reference to these computations we suggest the salient features of an experimental setup in which they might realized.
