Topological Dynamics in the Physical and Biological Sciences

We explain the relation between magnetic braids and their representation by the action of the corresponding Hamiltonian system. We show how this function captures certain topological properties of the braid and then go on to explore the role it has in the relaxation of magnetic braids under resistive dynamics at high magnetic Reynolds numbers.
