    • Domain growth in binary mixtures at low temperatures 

      Lacasta Palacio, Ana María; Hernández Machado, Aurora; Sancho, Jose Maria; Toral Garcés, Raúl (The American Physical Society, 1992-03-01)
      Article
      Accés obert
      We have studied domain growth during spinodal decomposition at low temperatures. We have performed a numerical integration of the deterministic time-dependent Ginzburg-Landau equation with a variable, concentration-dependent ...

    • Effects of domain morphology in phase-separation dynamics at low temperature. 

      Lacasta Palacio, Ana María; Sancho, Jose Maria; Hernández Machado, Aurora; Toral, Raul. (American Physical Society, 1993-09-01)
      Article
      Accés obert
      We present numerical results of the deterministic Ginzburg-Landau equation with a concentration-dependent diffusion coefficient, for different values of the volume fraction phi of the minority component. The morphology of ...

    • Fluctuations in domain growth: Ginzburg-Landau equations with multiplicative noise 

      Ramírez de la Piscina Millán, Laureano; Sancho, Jose Maria; Hernández Machado, Aurora (The American Physical Society, 1993-07-01)
      Article
      Accés obert
      Ginzburg-Landau equations with multiplicative noise are considered, to study the effects of fluctuations in domain growth. The equations are derived from a coarse-grained methodology and expressions for the resulting ...

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

      González Cinca, Ricardo; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume; Hernández Machado, Aurora; Toth-Katona, T; Börzsönyi, T; Buka, A (1998-10)
      Article
      Accés restringit per política de l'editorial
      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 ...

    • Numerical algorithm for Ginzburg-Landau equations with multiplicative noise: application to domain growth 

      Ramírez de la Piscina Millán, Laureano; Sancho, Jose Maria; Hernández Machado, Aurora (The American Physical Society, 1993-07-01)
      Article
      Accés obert
      We consider stochastic partial differential equations with multiplicative noise. We derive an algorithm for the computer simulation of these equations. The algorithm is applied to study domain growth of a model with a ...
