Аннотация:Cluster formation is a focus of interdisciplinaryresearch in both chemistry and physics. Here we discuss the exoticexample of this phenomenon in the vortex matter of a thinsuperconductor. In superconducting films, the clustering takesplace because of particular properties of the vortex interactions inthe crossover or intertype regime between superconductivity typesI and II. These interactions are controlled by the two parametersthat are responsible for the crossover, Ginzburg−Landauparameter κ, which specifies the superconducting material of thefilm, and film thickness d, which controls effects due to straymagnetic fields outside the sample. We demonstrate that theircompetition gives rise to a complex spatial dependence of theinteraction potential between vortices, favoring the formation ofchainlike vortex clusters.
