DESCRIPTION In the context of Superconductivity , a fluxon (aka Abrikosov Vortex ) is a small whisker of normal phase surrounded by superconducting phase. Supercurrent s circulate around its center. The magnetic field through such a whisker and its neighborhood, which has size of the order of London penetration depth ( nm), is quantized because of the phase properties of the Magnetic Vector Potential in Quantum Electrodynamics . In the context of Long Josephson Junction s, a fluxon (aka Josephson Vortex ) is made of circulating Supercurrent s and has ''no'' normal core. Supercurrents circulate just around mathematical center of a fluxon. Again, the magnetic flux created by circulating Supercurrent s is equal to a Magnetic Flux Quantum . In the context of numerical MHD modeling, a fluxon is a discretized magnetic field line, representing a finite amount of magnetic flux in a localized bundle in the model. Fluxon models are explicitly designed to preserve the Topology of the magnetic field, overcoming Numerical Resistivity effects in Eulerian models. |
