Symmetry breaking of magnetic vortices before annihilation (APL Cover)

In this work we created two unique energy landscapes by applying a magnetic force field parallel and anti-parallel to to the vortex polarity. This lead to the breakdown of the rotational symmetry of the vortex state into unique asymmetric identities.
