Stable Vortex-Antivortex Molecules in Mesoscopic Superconducting Triangles
Abstract
A thermodynamically stable vortex-antivortex pattern has been revealed in equilateral mesoscopic typeI superconducting triangles, contrary to typeII superconductors where similar patterns are unstable. The stable vortex-antivortex “molecule” appears due to the interplay between two factors: a repulsive vortex-antivortex interaction in typeI superconductors and the vortex confinement in the mesoscopic triangle.
