Dipolar interactions induced order in assemblies of magnetic particles
Pastor Satorras, Romualdo; Rubí Capaceti, José Miguel (2000-10-27)
Article
Accés obertWe discuss the appearance of ordered structures in assemblies of magnetic particles. The phenomenon occurs when dipolar interactions and the thermal motion of the particles compete, and is mediated by screening and excluded ... -
Disorder-induced temperature fluctuations in nonequilibrium systems
Díaz Guilera, Albert; Torner Sabata, Lluís; Rubí Capaceti, José Miguel (1992-01)
Article
Accés restringit per política de l'editorialThe authors study the effects on heat diffusion related to the presence of a quenched disorder of impurities at the boundaries. A simple lattice model summarizes the main characteristics of the surface through which the ... -
Finite-size effects in nonequilibrium correlation functions
Torner Sabata, Lluís; Rubí Capaceti, José Miguel (1991-07)
Article
Accés restringit per política de l'editorialWe have shown that finite-size effects in the correlation functions away from equilibrium may be introduced through dimensionless numbers: the Nusselt numbers, accounting for both the nature of the boundaries and the size ... -
Fractal properties of cluster of colloidal magnetic particles
Pastor Satorras, Romualdo; Rubí Capaceti, José Miguel (1998-05)
Article
Accés restringit per política de l'editorialWe have studied the properties of clusters of colloidal magnetic particles generated from a 2D aggregation model with dipolar interparticle interactions. Particles diffuse off-lattice, experiencing dipolar 1 with the already ... -
Long-range-interaction induced ordered structures in deposition processes
Pastor Satorras, Romualdo; Rubí Capaceti, José Miguel (American Institute of Physics (AIP), 1998-06-15)
Article
Accés obertWe present a new model of sequential adsorption in which the adsorbing particles experience dipolar interactions. We show that in the presence of these long-range interactions, highly ordered structures in the adsorbed ... -
Model of correlated sequential adsorption of colloidal particles
Pastor Satorras, Romualdo; Rubí Capaceti, José Miguel (2001-06-11)
Article
Accés obertWe present results of a model of sequential adsorption in which the adsorbing particles are correlated with the particles attached to the substrate. The strength of the correlations is measured by a tunable parameter s. ... -
On fluctuations in interfacial fluid systems
Torner Sabata, Lluís; Rubí Capaceti, José Miguel; Díaz Guilera, Albert (1989-06)
Article
Accés restringit per política de l'editorialWe study the propagation of the temperature fluctuations in a system in the presence of an interface. Such fluctuations originate from surface noise sources which are introduced through the random parts of the interfacial ... -
Particle-cluster aggregation with dipolar interactions
Pastor Satorras, Romualdo; Rubí Capaceti, José Miguel (1995-06)
Article
Accés obertThe properties of aggregates generated from an off-lattice, two-dimensional, particle-cluster aggregation model with dipolar interparticle interactions have been investigated. The fractal dimension seems to be a monotonically ... -
Spatial correlations for temperature fluctuations from surface noise
Rubí Capaceti, José Miguel; Díaz Guilera, Albert; Torner Sabata, Lluís (1987-02)
Article
Accés restringit per política de l'editorialThe equal-time or static temperature correlation function from fluctuations originated at a surface is computed. Such fluctuations come from a random heat flux appearing in Newton's law of cooling. The correlation is studied ... -
Stationary states and phase diagram for a model of the Gunn effect under realistic boundary conditions
Gomila Lluch, Gabriel; Rubí Capaceti, José Miguel; Rodríguez Cantalapiedra, Inma; Bonilla, L. L. (The American Physical Society, 1997-08-01)
Article
Accés obertA general formulation of boundary conditions for semiconductor-metal contacts follows from a phenomenological procedure sketched here. The resulting boundary conditions, which incorporate only physically well-defined ...
