1. Estudo de um sistema clÃssico de dipolos magnÃticos carregados em estruturas de bicamadas. / Study of a classical bilayer system of charged magnetic dipoles
Estudamos as estruturas e as propriedades dinÃmicas de um cristal clÃssico bidimensional (2D) em bicamadas de partÃculas dipolares magnÃticas carregadas em um arranjo no qual os dipolos sÃo perpendiculares Ãs camadas e com mesma densidade de partÃculas em cada camada. A energia do sistema à devido à interaÃÃo carga - carga (interaÃÃo coulom- bia

2. Transições de fase em modelos magnéticos bi-dimensionais com interações dipolares.
In this work we have used the numerical Monte Carlo simulations to simulate the planar to paramagnetic phase transition in the anisotropic Heisenberg model with dipolar interactions (AH-d model). We concentrated our attention in three slightly different models the AH-d model in a bilayer system with a cut-off in the dipolar interactions, the dipolar Planar R

3. Simulações numéricas de Monte Carlo aplicadas no estudo das transições de fase do modelo de Ising dipolar bidimensional / Numerical Monte Carlo simulations applied to study of phase transitions in two-dimensional dipolar Ising model
Two-dimensional spin model with nearest-neighbor ferromagnetic interaction and long-range dipolar interactions exhibit a rich phase diagram, whose characteristics have been exploited by several studies in the recent literature. Furthermore, the possibility of explain observed phenomena in ultrathin magnetic films, which have many technological applications,

4. A 5-nanosecond molecular dynamics trajectory for B-DNA: analysis of structure, motions, and solvation.
We report the results of four new molecular dynamics (MD) simulations on the DNA duplex of sequence d(CGCGAATTCGCG)2, including explicit consideration of solvent water, and a sufficient number of Na+ counterions to provide electroneutrality to the system. Our simulations are configured particularly to characterize the latest MD models of DNA, and to provide
