1. Zeros de Fisher e aspectos críticos do modelo de Ising dipolar / Fisher\ s zeros and critical aspects of the dipolar Ising model
We study the critical behavior of the dipolar Ising model on two-dimensional regular lattices. This model presents a phenomenologically rich scenario due to the effect of frustration caused by the competition between the pure Ising interaction and the dipolar one. To study the criticality of this model we apply finite size scaling relations for the partition

2. Simulações microcanônicas de proteínas / Microcanonical Simulations of Proteins
Transições de fase termodinâmicas são usualmente estudadas por meio do ensemble canônico e estão associadas a sistemas macroscópicos. Entretanto, tem-se tornado cada vez mais frequente e importante o estudo de sistemas físicos pequenos, cujos alcances característicos das interações equivalem aos tamanhos dos sistemas. Nestes casos pode haver inequ

3. Models with infinitely many absorbing states analitically soluble / Modelos com infinitos estados absorventes analiticamente solúveis
In this work we studied some models with particle conservation which present a phase transition between an active stationary state and infinitely many absorbing states. The active states of each model consist of equiprobable configurations, corresponding, according to Gibbs s formulation of Statistical Mechanics, to a microcanonical ensemble. Carrying out an

4. Proposta e implementação de um sistema de processamento paralelo para dinâmica molecular. / Proposal and implementation of a parallel processing system for molecular dynamics.
A method for parallelization of molecular dynamics simulations in distributed memory machines operating under the message-passing paradigm is proposed. Even though the analysis and implementation presented in this work were primarily restricted to the system model known as microcanonical emsemble of Lennard--Jones particles. the obtained system can easily be
