  • Competitive evaporation in arrays of droplets 

    Lacasta Palacio, Ana María; Sokolov, Igor M.; Sancho, Jose Maria; Sagués Mestre, Francesc (American Physical Society, 1998-05-31)
    Article
    Open Access
    We consider the evaporation of periodic arrays of initially equal droplets in two-dimensional systems with open ~absorbing! boundaries. Our study is based on the numerical solution of the Cahn-Hilliard equation. We show ...
  • Diffusion on Solid Surface: anomalous is Normal 

    Sancho, Jose Maria; Lacasta Palacio, Ana María; Lindenberg, K.; Sokolov, Igor M.; Romero, A. H. (American Physical Society, 2004-06-23)
    Article
    Open Access
    We present a numerical study of classical particles diffusing on a solid surface. The particles’ motion is modeled by an underdamped Langevin equation with ordinary thermal noise. The particle-surface interaction is described ...
  • Dispersionless transport in a washboard potential 

    Lindenberg, K.; Sancho, Jose Maria; Lacasta Palacio, Ana María; Sokolov, Igor M. (American Physical Society, 2007-01-10)
    Article
    Open Access
    We study and characterize a new dynamical regime of underdamped particles in a tilted washboard potential. We find that for small friction in a finite range of forces the particles move essentially nondispersively, that ...
  • Evaporation and coarsening dynamics with open boundaries 

    Lacasta Palacio, Ana María; Sagués Mestre, Francesc; Sancho, Jose Maria; Sokolov, Igor M. (Americah Physical Society, 1999-01-31)
    Article
    Open Access
    We present a study of the evaporation dynamics of a substance undergoing a coarsening process. The system is modeled by the Cahn-Hilliard equation with absorbing boundaries. We have found that the dynamics, although of ...
  • From subdiffusion to superdiffusion of particles on solid surfaces 

    Lacasta Palacio, Ana María; Sancho, Jose Maria; Sokolov, Igor M.; Lindenberg, K. (American Physical Society, 2004-11-15)
    Article
    Open Access
    We present a numerical and partially analytical study of classical particles obeying a Langevin equation that describes diffusion on a surface modeled by a two dimensional potential. The potential may be either periodic ...
  • Study of a bimolecular annihilation process for coarsening reactants 

    Lacasta Palacio, Ana María; Sagués Mestre, Francesc; Sokolov, Igor M.; Sancho, Jose Maria (American Institute of Physics, 1999-04-30)
    Article
    Open Access
    We consider the spatio-temporal behavior of the A+B→0 bimolecular reaction in a system where both reactants tend to segregate into separated phases. Our study is based on the numerical solution of a pair of reaction–diffusion ...
