We have investigated superconductivity in thin mesoscopic regular polygons in a perpendicular magnetic field. For that, we have used an analytical gauge transformation for the vector potential which takes into account the superconductor/vacuum boundary condition. As reported previously, this has opened the way to investigate the nucleation of superconductivity in nanosu-perconductors at the normal-superconducting phase boundary in the framework of the linearized Ginzburg-Landau (GL) equations. We report now on the extension of this work to the superconducting phase beyond the phase boundary, by using the full non-linear GL equations. The stability in the superconducting phase of the symmetry induced vortex-antivortex molecules has been examined in detail for squared and equilateral triangle geometries. |
