    • Comment on "Diffusion on solif surfaces: anomalous is normal"-Reply 

      Sancho, Jose Maria; Lacasta Palacio, Ana María; Lindenberg, K.; Sokolov, Igor M.; Romero, A. H. (Americah Physical Society, 2005-05-12)
      Article

    • 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
      Accés obert
      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
      Accés obert
      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
      Accés obert
      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 ...

    • Emergence of Polarized Ideological Opinions in Multidimensional Topic Spaces 

      Baumann, Fabian; Lorenz-Spreen, Philipp; Sokolov, Igor M.; Starnini, Michele (2021-01-20)
      Article
      Accés obert
      Opinion polarization is on the rise, causing concerns for the openness of public debates. Additionally, extreme opinions on different topics often show significant correlations. The dynamics leading to these polarized ...

    • 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
      Accés obert
      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
      Accés obert
      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
      Accés obert
      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 ...
