We numerically examine the manipulation of vortices interacting with a movingtrap representing a magnetic force tip translating across a superconductingsample containing a periodic array of pinning sites. As a function of the tipvelocity and coupling strength, we find five distinct dynamic phases, includinga decoupled regime where the vortices are dragged a short distance within apinning site, an intermediate coupling regime where vortices in neighboringpinning sites exchange places, an intermediate trapping regime where individualvortices are dragged longer distances and exchange modes of vortices occur inthe surrounding pins, an intermittent multiple trapping regime where the trapswitches between capturing one or two vortices, and a strong couping regime inwhich the trap permanently captures and drags two vortices. In some regimes weobserve the counterintuitive behavior that slow moving traps couple lessstrongly to vortices than faster moving traps; however, the fastest movingtraps are generally decoupled. The different phases can be characterized by thedistances the vortices are displaced and the force fluctuations exerted on thetrap. We find different types of stick-slip motion depending on whethervortices are moving into and out of pinning sites, undergoing exchange, orperforming correlated motion induced by vortices outside of the trap. Ourresults are general to the manipulation of other types of particle-basedsystems interacting with periodic trap arrays, such as colloidal particles orcertain types of frictional systems.
