For example, three-component Heisenberg ferromagnets can be made to become XY and even Ising-like by application of an alternate field, thus changing the topology of defects and the nature of their ordered phase. This suggests that quite generally one can use external a.c. fields to tailor the symmetry (sub)groups of a statistical problem at will. Another example may have applications in biothecnology: By applying a rotating field to a subset of particles in a many-particle system, one can induce a phase-separation between the ensembles of rotated and non-rotated particles. This yields a method for the separation of magnetically marked cells in suspension. Such richness of amusing and perhaps useful phenomena is in contrast with the extreme poverty of methods and concepts we have to study them.
