Abstract

We develop a new condensed matter theory of the formation of thermodynamically stable vortex structures in quantum nanowires. We write down the Gibbs free energy functional for the systems and we minimise the free energy to obtain the optimal position of vortices for different applied fields and temperatures. We also study the nucleation of vortices in, and their escape from, the nanostructural superconductors.
