Langevin dynamics of A+A reactions in one dimension
Sancho, Jose Maria; Romero, A. H.; Lacasta Palacio, Ana María; Lindenberg, Katja (IOP Publishing, 2007-02-28)
Article
Accés obertWe propose a set of Langevin equations of motion together with a reaction rule for the study of binary reactions. Our scheme is designed to address this problem for arbitrary friction ° and temperature T. It easily ... -
Numerical study of A+A -> 0 and A+B ->0 reactions with inertia
Romero, A. H.; Lacasta Palacio, Ana María; Sancho, Jose Maria; Lindenberg, Katja (American Institute of Physics, 2007-11-30)
Article
Accés obertUsing numerical methods we study the annihilation reactions A + A → 0 and A + B → 0 in one and two dimensions in the presence of inertial contributions to the motion of the particles. The particles move freely following ... -
Sorting of mesoscopic particles driven through periodic potential landscapes
Lacasta Palacio, Ana María; Khoury, M.; Sancho, Jose Maria; Lindenberg, Katja (World Scientific Publishing, 2006-10-01)
Article
Accés obertSorting of colloidal particles of different sizes is of importance in the transport and delivery of such particles in biological, materials science, and other technological contexts. A successful methodology involves the ... -
Speeding chemical reactions by focusing
Lacasta Palacio, Ana María; Ramírez de la Piscina Millán, Laureano; Sancho Herrero, José María; Lindenberg, Katja (2013-04-11)
Article
Accés obertWe present numerical results for a chemical reaction of colloidal particles which are transported by a laminar fluid and are focused by periodic obstacles in such a way that the two components are well mixed and consequently ... -
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'editorialWe 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 obertWe 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'editorialParticles 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 obertWe 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 ...
