  • 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
    Open Access
    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
    Open Access
    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
    Restricted access - publisher's policy
    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
    Open Access
    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 ...
