Collisionless relaxation in gravitacional systems from violent relaxation to gravothermal collapse
(2008) [Artigo de periódico]Theory and simulations are used to study collisionless relaxation of a gravitational N-body system. It is shown that when the initial one-particle distribution function satisfies the virial condition—potential energy is ... -
Geometry of phase separation
(2009) [Artigo de periódico]We study the domain geometry during spinodal decomposition of a 50:50 binary mixture in two dimensions. Extending arguments developed to treat nonconserved coarsening, we obtain approximate analytic results for the ... -
Modelos dinâmicos para segregação granular
(2003) [Dissertação]Materiais granulares, quando submetidos a vibrações, apresentam o fenômeno de compactação lenta, durante o qual o volume livre disponível aos grãos diminui, e sua mobilidade decai a zero. Nesta situação espera-se o fenômeno ... -
Nova abordagem para modelagem da formação de membranas poliméricas por inversão de fases
(2023) [Tese]A modelagem numérica da formação de membranas poliméricas via precipitação por imersão tem importância fundamental para prever a morfologia das estruturas obtidas. Neste trabalho, uma nova abordagem do modelo de campo de ... -
Phase separation in Cu/sub 90/Co/sub 10/ high-magnetoresistance materials
(2003) [Artigo de periódico]The relation between giant magnetoresistance ~GMR! and phase separated nanostructures in Cu90Co10 is studied using magnetotransport measurements together with transmission electron microscopy and x-ray microanalysis. The ... -
A self-consistent renormalized jellium approach for calculating structural and thermodynamic properties of charge stabilized colloidal suspensions
(2009) [Artigo de periódico]An approach is proposed which allows to self-consistently calculate the structural and the thermodynamic properties of highly charged aqueous colloidal suspensions. The method is based on the renormalized jellium model ... -
The renormalized jellium model for spherical and cylindrical colloids
(2007) [Artigo de periódico]Starting from a mean-field description for a dispersion of highly charged spherical or (parallel) rodlike colloids, we introduce the simplification of a homogeneous background to include the contribution of other polyions ...
