    • The rich phenomenology of brownian particles in nonlinear potential landscapes 

      Sancho, Jose Maria; Lacasta Palacio, Ana María (2010-09)
      Article
      Accés obert
      Abstract. Non-interacting brownian particles follows Langevin equations fullfiling fluctuation–dissipation relation between friction and thermal noise. Under a linear potential (constant force) Einstein found a relation ...
    • Towards gender equity in Spanish universities: a long and unpaved road 

      Sancho, Jose Maria; Creus, A. S.; Hemosilla, P. (Global University Network for Innovation (GUNI), 2008)
      Article

    • 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 ...
    • Wave competition in excitable modulated media 

      Sendiña-Nadal, I.; Gómez Gesteira, Moncho; Pérez Muñuzuri, Vicente; Pérez Villar, Vicente; Armero, J.; Ramírez de la Piscina Millán, Laureano; Casademunt, Jaume; Sancho, Jose Maria; Sagués Mestre, Francesc (American Physical Society, 1997-12-31)
      Article
      Accés obert
      The propagation of an initially planar front is studied within the framework of the photosensitive Belousov- Zhabotinsky reaction modulated by a smooth spatial variation of the local front velocity in the direction perpendicular ...
    • Wave propagation in a medium with disordered excitability 

      Sendiña-Nadal, I.; Pérez Muñuzuri, Alberto; Vives, D.; Pérez Muñuzuri, Vicente; Casademunt, Jaume; Ramírez de la Piscina Millán, Laureano; Sancho, Jose Maria; Sagués Mestre, Francesc (American Physical Society, 1998-06-30)
      Article
      Accés obert
      The effect of quenched disorder on the propagation of autowaves in excitable media is studied both experimentally and numerically in relation to the light-sensitive Belousov-Zhabotinsky reaction. The spatial disorder is ...
    • 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 ...
