 abstract = {Ground-state properties of a two-dimensional system of superconducting
vortices in the presence of a periodic array of strong pinning centers
are studied analytically and numerically. The ground states of the
vortex system at different filling ratios are obtained using a simple
geometric argument under the assumption that the penetration depth is
much smaller than the spacing of the pin lattice. The results of this
calculation are confirmed by numerical studies in which simulated
annealing is used to locate the ground states of the vortex system. The
zero-temperature equilibrium magnetization as a function of the applied
field is obtained by numerically calculating the energy of the ground
state for a large number of closely spaced filling ratios. The results
show interesting commensurability effects such as plateaus in the B-H
diagram at simple fractional filling ratios.},
