Stable Knots and Links in Electromagnetic Fields

Abstract: Persistent topological structures in physical systems have become increasingly important over the last years. Electromagnetic fields with knotted field lines play a special role among these, since they can be used to transfer their knottedness to other systems like plasmas and quantum fluids. In null electromagnetic fields the electric and the magnetic field lines evolve like unbreakable elastic filaments in a fluid flow. In particular, their topology is preserved for all time, so that all knotted closed field… Show more

“…Thus, it remains to demonstrate that the conclusions of astrophysicists are strongly backed up by the fundamental laws/principles of quantum mechanics and electrodynamics. This then will help us to strengthen the arguments by astrophysicists by accounting for the knotty nature of the Maxwellian electrodynamics [15,41,54,55,63,80]. The existing quantization for electromagnetic fields do not contain any information about knots/links.…”

“…Therefore, Equation ( 59) implies that such PEP's are all massive nonhyperbolic knots. In the presence of boundaries, the formation of hyperbolic knots is also possible, as discussed in detail in [55] and differently in [80]. However, the negativity of masses is unphysical and, therefore such (hyperbolic) knots must be discarded.…”
