  • Het diffusion anisotropy in dendritic growth: phase field simulations and experiments in liquid crystals 

    González Cinca, Ricardo; Ramírez de la Piscina Millán, Laureano; Casademunt, Jaume; Hernández Machado, A.; Toth-Katona, T.; Borzsonyi, T.; Buka, A. (Elsevier, 1998-10-15)
    Article
    Restricted access - publisher's policy
    An anisotropic heat diffusion coefficient is introduced in order to study some interfacial growth phenomena. This anisotropy has been incorporated in a phase field model which has been studied numerically to reproduce some ...

    El trabajo resume los resultados de la aplicación de la Combinatoria Poliédrica al Problema del Viajante (TSP): definición del poliedro, dimensión, desigualdades válidas, facetas. Estos resultados se aplican al caso concreto ...
  • Pattern formation during mesophase growth in a homologous series 

    Tóth Katona, T.; Börzsönyi, T.; Váradi, Z.; Szabon, J.; Buka, A.; González Cinca, Ricardo; Ramírez de la Piscina Millán, Laureano; Casademunt, Jaume; Hernández-Machado, Aurora (American Physical Society, 1996-08-01)

    Remarkable differences in the shape of the nematic-smectic-B interface in a quasi-two-dimensional geometry have been experimentally observed in three liquid crystals of very similar molecular structure, i.e., neighboring ...
  • Phase field simulations and experiments of faceted growth in liquid crystals 

    González Cinca, Ricardo; Ramírez de la Piscina Millán, Laureano; Casademunt, Jaume; Hernández-Machado, Aurora; Kramer, L.; Tóth Katona, T.; Börzsönyi, T.; Buka, A. (Elsevier Science, 1996-12-01)
    Article

    We present numerical simulations directed at the description of smectic-B germs growing into the supercooled nematic phase for two different liquid crystalline substances. The simulations are done by means of a phase-field ...
