Evolution of topological defect motifs and the stress patterns with the approach of the two impurity particles. The vertices in the plot represent the centers of particles. (Upper) Arrangement of nearby particles around the impurity particles. Disclinations of different types are distinguished by colors; red for fivefold disclination, blue for sevenfold disclination, black for eightfold disclination, and orange for ninefold disclination. (Lower) The corresponding stressed regions. The energy of the system is reduced from A to B with the mediation of defects. (A) Inline graphic, (B) Inline graphic, and (C) Inline graphic.
