Magnetic braids, Hamiltonian action and selective decay

Date: 
Tuesday 14th August 2012 - 11:30 to 12:30
Venue: 
INI Seminar Room 1
Abstract: 
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.
