(a) The vortex-vortex interaction energy, as a function of the distance between vortices, for parameters leading to pairwise vortex attraction (σSN > 0, see open dots). Nevertheless, the short-range repulsion between vortices arises for clusters comprising more than two vortices (insets depict the cumulative Cooper-pair density distribution for the considered clusters). (b) Maximum of the Cooper-pair density, nmax, inside the hexagonal vortex cluster for each band-condensate separately, shown as a function of vortex distance d between vortices. The shaded area delimits the short-range repulsion found for the hexagonal vortex cluster.
