(...) This group is studying vortices in the simplest of fluids, superfluid helium. In a normal liquid the constituent particles are distributed over many possible quantum-mechanical energy states. Constant collisions ensure that the behaviour on a microscopic level is a frantic redistribution of particles among the available states.
