Skyrmions in a ferromagnetic Bose-Einstein condensate
U. Al Khawaja, H. T. C. Stoof
The recently realized multicomponent Bose-Einstein condensates provide opportunities to explore the rich physics brought about by the spin degrees of freedom. For instance, we can…

Skyrmions in spinor Bose-Einstein condensates
H. T. C. Stoof
We show that spinor Bose-Einstein condensates not only have line-like vortex excitations, but in general also allow for point-like topological excitations, i.e., skyrmions. We disc…
