    • Transport and diffusion on a body-centered-cubic bcc(110) surface under a constant external force 

      Lindenberg, Katja; Lacasta Palacio, Ana María; Sancho, Jose Maria; Romero, Aldo H. (SPIE--The International Society for Optical Engineering, 2005-08-31)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      We present a numerical study of classical particles obeying a Langevin equation moving on a solid bcc(110) surface. The particles are subject to a two dimensional periodic and symmetric potential of rectangular symmetry ...

    • Transport and diffusion on crystalline surfaces under external forces 

      Lindenberg, Katja; Lacasta Palacio, Ana María; Sancho, Jose Maria; Romero, A. H. (IOP Publishing, 2005-01-31)
      Article
      Accés obert
      We present a numerical study of classical particles obeying a Langevin equation and moving on a solid crystalline surface under an external force that may either be constant or modulated by periodic oscillations. We focus ...

    • Weak disorder in periodic potentials: anomalous transport and diffusion 

      Lindenberg, Katja; Sancho, Jose Maria; Khoury Arvelo, María José; Lacasta Palacio, Ana María (2012-03-31)
      Article
      Accés restringit per política de l'editorial
      Particles driven through a periodic potential by an external constant force are known to exhibit a pronounced peak of the diffusion around the critical deterministic force that defines the transition between locked and ...

    • Weak Disorder: Anomalous Transport and Diffusion Are Normal Yet Again 

      Khoury Arvelo, María José; Lacasta Palacio, Ana María; Sancho, Jose Maria; Lindenberg, Katja (2011-03)
      Article
      Accés obert
      We carry out a detailed study of the motion of particles driven by a constant external force over a landscape consisting of a periodic potential corrugated by a small amount of spatial disorder. We observe anomalous ...
