Short-time dynamics of colloidal suspensions in confined geometries Pagonabarraga Mora, Ignacio Hagen, M. H. J. Lowe, C. P. Frenkel, Daan, 1948- Simulació per ordinador Reologia Col·loides Suspensions (Química) Computer simulation Rheology Colloids Suspensions (Chemistry) We analyze the short-time dynamical behavior of a colloidal suspension in a confined geometry. We analyze the relevant dynamical response of the solvent, and derive the temporal behavior of the velocity autocorrelation function, which exhibits an asymptotic negative algebraic decay. We are able to compare quantitatively with theoretical expressions, and analyze the effects of confinement on the diffusive behavior of the suspension. 2011-07-07T12:52:52Z 2011-07-07T12:52:52Z 1999 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: http://dx.doi.org/10.1103/PhysRevE.59.4458 Physical Review E, 1999, vol. 59, núm. 4, p. 4458-4469 http://dx.doi.org/10.1103/PhysRevE.59.4458 (c) American Physical Society, 1999 info:eu-repo/semantics/openAccess The American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
