摘要: Phenomenological Landau–de Gennes modelling based on the free energy of nematic liquid crystal colloids is reviewed. Nematic phase, gradient order, and surface anchoring contributions to total are used. The numerical finite difference relaxation technique explained as an efficient tool for minimisation energy. Effects mesh allocation discussed. Various conceptually different colloidal structures calculated show universality model. Single particles, dipolar–quadrupolar dimers, entangled dimers bound by escaped hyperbolic rings, hierarchically patterned Saturn-ring superstructures presented.
