摘要：

We show how to calculate semianalytically the dense vortex state in strong type-II superconducting nanostructures. For the specific case of a strip, we find vortex lattice solutions that also incorporate surface superconductivity. We calculate the energy cost to displace individual vortex rows parallel to the surfaces and find that this energy oscillates with the magnetic field. Remarkably, we also find that, at a critical field H* below H-c2, this "shear" energy becomes strictly zero for the surface rows due to an unexpected mismatch with the bulk lattice.
