Abstract
The vortex-vortex interaction potential in bulk superconductors is
calculated within the Ginzburg-Landau (GL) theory and is obtained from a
numerical solution of a set of two coupled nonlinear GL differential
equations for the vector potential and the superconducting order
parameter, where the merger of vortices into a giant vortex is allowed.
Further, the interaction potentials between a vortex and a giant vortex
and between a vortex and an antivortex are obtained for both type-I and
type-II superconductors. Our numerical results agree asymptotically with
the analytical expressions for large intervortex separations that are
available in the literature. We propose empirical expressions valid over
the full interaction range, which are fitted to our numerical data for
different values of the GL parameter.
