Linked and knotted beams of light
ORAL
Abstract
Maxwell's equations allow for curious solutions having linked and knotted field lines. A particularly striking solution is one characterized by the property that {\it all} electric and magnetic field lines are closed loops with {\it any } two electric(magnetic) field lines linked. These little known solutions, are based on the Hopf fibration and have a remarkably simple representation in terms of self-dual Chandrasekhar-Kendall curl eigenstates. I will discuss their structure, time evolution, physical properties and how they may be physically realizable.
