    • 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 ...

    • Periodic spiking by a pair of ionic channels 

      Ramírez de la Piscina Millán, Laureano; Sancho Herrero, José María (2018-09-01)
      Article
      Accés obert
      Neuronal cells present periodic trains of localized voltage spikes involving a large amount of different ionic channels. A relevant question is whether this is a cooperative effect or it could also be an intrinsic property ...

    • 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
      Accés restringit per política de l'editorial
      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 ...

      Ramírez de la Piscina Millán, Laureano; Sancho Herrero, José María (Springer, 2018-01-15)
      Article
      Accés obert
      Experiments on single ionic channels have contributed to a large extent to our current view on the function of cell membrane. In these experiments the main observables are the physical quantities: ionic concentration, ...
