Pinning effects in a two-dimensional cluster glass

We study numerically the glass formation and depinning transition of a system two-dimensional cluster-forming monodisperse particles in presence pinning disorder. The pairwise interaction potential is nonmonotonic, motivated by intervortex forces type-$1.5$ superconductors. Such systems can form cluster glasses due to interactions following thermal quench, without underlying effects vortex these systems. find that small density centers moderate depth has limited effect on formation, i.e., dominated interactions. At higher densities significantly affect formation. depinning, under constant driving force, found be plastic, with features distinct from non-cluster-forming such as clusters merging breaking. general vortices exhibit stronger than regular vortices.
