Influence of competition in minimal systems with discontinuous absorbing phase transitions
Salete Pianegonda, C. E. Fiore
Contact processes (CP's) with particle creation requiring a minimal neighborhood (restrictive or threshold CP's) present a novel sort of discontinuous absorbing transitions, that r…
Contact processes with competitive dynamics in bipartite lattices: Effects of distinct interactions
Salete Pianegonda, Carlos E. Fiore
The two-dimensional contact process (CP) with a competitive dynamics proposed by Martins {\it et al.} [Phys. Rev. E {\bf 84}, 011125(2011)] leads to the appearance of an unusual ac…
The renormalized jellium model for spherical and cylindrical colloids
Salete Pianegonda, Emmanuel Trizac, Yan Levin
Starting from a mean-field description for a dispersion of highly charged spherical or (parallel) rod-like colloids, we introduce the simplification of a homogeneous background to…
Charge reversal of colloidal particles
S. Pianegonda, Marcia C. Barbosa, Yan Levin
A theory is presented for the effective charge of colloidal particles in suspensions containing multivalent counterions. It is shown that if colloids are sufficiently strongly char…
Inequalities of wealth distribution in a conservative economy
S. Pianegonda, J. R. Iglesias
We analyze a conservative market model for the competition among economic agents in a close society. A minimum dynamics ensures that the poorest agent has a chance to improve its e…
Wealth redistribution with finite resources
S. Pianegonda, J. R. Iglesias, G. Abramson +1
We present a simplified model for the exploitation of finite resources by interacting agents, where each agent receives a random fraction of the available resources. An extremal dy…
