  • Front and domain growth in the presence of gravity. 

    Lacasta Palacio, Ana María; Hernández-Machado, Aurora; Sancho, Jose Maria (American Physical Society, 1993-10-01)
    Article
    Open Access
    Front and domain growth of a binary mixture in the presence of a gravitational field is studied. The interplay of bulk (and surface) diffusion mechanisms is analyzed. An equation for the evolution of interfaces is derived ...
  • Growth of unstable interfaces in disordered media 

    Lacasta Palacio, Ana María; Ramírez de la Piscina Millán, Laureano; Casademunt, Jaume; Hernández-Machado, Aurora; Rodríguez, M. A. (American Physical Society, 1998-05-31)
    Article
    Open Access
    The effects of a disordered medium in the growth of unstable interfaces are studied by means of two local models with multiplicative and additive quenched disorder, respectively. For short times and large pushing ...
  • Interfacial instability induced by external fluctuations 

    Mozos, J. L.; Lacasta Palacio, Ana María; Ramírez de la Piscina Millán, Laureano; Hernández-Machado, Aurora (American Physical Society, 1996-02-01)
    Article
    Open Access
  • 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)
    Article
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    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 ...
  • Phase-field model of Hele-Shaw flows in the high-viscosity constrast regime 

    Hernández-Machado, Aurora; Lacasta Palacio, Ana María; Mayoral, E.; Corvera Poiré, E. (American Physical Society, 2003-10-29)
    Article
    Open Access
    A one-sided phase-field model is proposed to study the dynamics of unstable interfaces of Hele-Shaw flows in the high viscosity contrast regime. The corresponding macroscopic equations are obtained by means of an asymptotic ...
