Vortex configurations in large superconducting mesoscopic triangles

In this work we study vortex configurations in mesoscopic equilateral triangles (for triangles whose sides are much smaller than the effective penetration length) within the London limit. Therefore we are able to investigate samples whose size is much larger than the coherence length. We calculate analytically the vortex-vortex interaction by adding image vortices outside the triangular domain. The vortex configurations were found by letting the vortex system evolve in time using a Langevin dynamics simulation. This allowed us to study the dependence of the vorticity on the magnetic field. Moreover, we also investigated the role of the surface barrier on the vortex entry into the superconducting triangle.
