Phys. Rev. E 77, 061706 (2008) [4 pages]Hierarchical self-assembly of nematic colloidal superstructuresReceived 10 October 2007; published 12 June 2008 We show that colloidal superstructures could be assembled in mixtures of large and small colloidal particles dispersed in a nematic liquid crystal. Using elastic interaction of small colloidal particles with the disclination lines we succeed to demonstrate how one can decorate with small particles a topological matrix of defect rings and loops formed by an array of large colloidal particles. Our simulations show that this concept of colloidal self-assembly in nematics could be extended down to the nanoscale particles. © 2008 The American Physical Society URL:
