Jamming as a random first-order percolation transition
Antonio Piscitelli, Antonio Coniglio, Annalisa Fierro +1
We determine the dimensional dependence of the percolative exponents of the jamming transition via numerical simulations in four and five spatial dimensions. These novel results co…
Relaxation functions and dynamical heterogeneities in a model of chemical gel interfering with glass transition
Antonio de Candia, Annalisa Fierro, Raffaele Pastore +2
We investigate the heterogeneous dynamics in a model, where chemical gelation and glass transition interplay, focusing on the dynamical susceptibility. Two independent mechanisms g…
Emergence of complex behavior in gelling systems starting from simple behavior of single clusters
A. Fierro, T. Abete, A. Coniglio
A theoretical and numerically study of dynamical properties in the sol-gel transition is presented. In particular, the complex phenomenology observed experimentally and numerically…
Dynamical heterogeneity in a model for permanent gels: Different behavior of dynamical susceptibilities
T. Abete, A. de Candia, E. Del Gado +2
We present a systematic study of dynamical heterogeneity in a model for permanent gels, upon approaching the gelation threshold. We find that the fluctuations of the self intermedi…
Dynamic heterogeneities in attractive colloids
A. Fierro, E. Del Gado, A. de Candia +1
We study the formation of a colloidal gel by means of Molecular Dynamics simulations of a model for colloidal suspensions. A slowing down with gel-like features is observed at low…
Static and dynamic heterogeneities in irreversible gels and colloidal gelation
A. Coniglio, T. Abete, A. de Candia +2
We compare the slow dynamics of irreversible gels, colloidal gels, glasses and spin glasses by analyzing the behavior of the so called non-linear dynamical susceptibility, a quanti…
Static and dynamic heterogeneities in a model for irreversible gelation
T. Abete, A. de Candia, E. Del Gado +2
We study the structure and the dynamics in the formation of irreversible gels by means of molecular dynamics simulation of a model system where the gelation transition is due to th…
Granular segregation under vertical tapping
M. Pica Ciamarra, M. D. De Vizia, A. Fierro +3
We present extensive Molecular Dynamics simulations on species segregation in a granular mixture subject to vertical taps. We discuss how grain properties, e.g., size, density, fri…
Columnar and lamellar phases in attractive colloidal systems
A. de Candia, E. Del Gado, A. Fierro +3
In colloidal suspensions, the competition between attractive and repulsive interactions gives rise to a rich and complex phenomenology. Here, we study the equilibrium phase diagram…
Colloidal gelation, percolation and structural arrest
A. de Candia, E. Del Gado, A. Fierro +2
By means of molecular dynamics, we study a model system for colloidal suspensions where the interaction is based on a competition between attraction and repulsion. At low temperatu…
Slow dynamics in gelation phenomena: From chemical gels to colloidal glasses
E. Del Gado, A. Fierro, L. de Arcangelis +1
We here discuss the results of 3d MonteCarlo simulations of a minimal lattice model for gelling systems. We focus on the dynamics, investigated by means of the time autocorrelation…
A unifying model for chemical and colloidal gels
E. Del Gado, A. Fierro, L. de Arcangelis +1
We investigate the slow dynamics in gelling systems by means of MonteCarlo simulations on the cubic lattice of a minimal statistical mechanics model. By opportunely varying some mo…
