Description
I will give a review of the theoretical and experimental
studies on the so-called topological vortex formation, in
which a vortex-free spin-1 BEC is manipulated adiabatically
using external magnetic fields into a state which contains a
multiply quantized vortex. Even vortex pumping can be
obtained to create deterministically vortices with high
quantum numbers. Very recently, we extended this idea for a
non-trivial three-dimensional case, in which Dirac monopoles
can be created. This observation takes BEC to have high
potential for the first experimental observation of Dirac
monopoles, analogs of magnetic monopoles, in any quantum field.
