Topological Dynamics in the Physical and Biological Sciences

Mass transport by the motion of 3D vortex filaments is studied. Perhaps the simplest example of such a transport is one by a vortex ring. As another example, we recently demonstrated that a 3D vortex soliton (Hasimoto soliton) can also transport mass along with its propagation. The common features of the transport, one by a vortex ring and the other by a vortex, is that some fluid particles move in closed orbits which make knots with the vortices. For the analysis of the mechanism of this trapping, a model composed of two straight vortex filaments in the 3D space, which is called the chopsticks model, is presented. We report mass transport by this model.
