Critical dynamics and global persistence in a probabilistic three-states cellular automaton
Roberto da Silva, Nelson Alves
In this work a three-states cellular automaton proposed to describe part of a biological immune system is revisited. We obtain the dynamic critical exponent of the model by mea…

Structural transitions in biomolecules - a numerical comparison of two approaches for the study of phase transitions in small systems
Nelson A. Alves, U. H. E. Hansmann, Y. Peng
We compare two recently proposed methods for the characterization of phase transitions in small systems. The usefulness of these techniques is evaluated for the case of structural…

Numerical study of the decay amplitudes in two dimensional QCD
E. Abdalla, N. Alves
After presenting a survey of theoretical results concerning the structure of two-dimensional QCD, we present a numerical study related to the mass eigenstates and the decay amplitu…
