1. Análise da dinâmica do funcionamento de lasers de fibra dopada com Érbio sob a óptica da equação de Ginzburg-Landau
Neste trabalho é apresentado um estudo baseado em análise numérica de lasers à fibra dopada com Érbio utilizando a técnica de acoplamento passivo de modos para que o mesmo opere em regime pulsado. A equação que descreve a dinâmica de uma cavidade laser é conhecida como Equação de Ginzburg-Landau, que neste trabalho é resolvida numericamente pelo

2. Vortex dynamics equation in type-II superconductors in a temperature gradient
In this work we determined a vortex dynamics equation in a temperature gradient in the frame of the time dependent Ginzburg-Landau equation. In this sense, we derived a local solvability condition, which governs the vortex dynamics. Also, we calculated the explicit form for the force coefficients, which are the keys for the understanding of the balance equat

3. Weak three dimensionality of a flow around a slender cylinder: the Ginzburg-Landau equation
In this paper a weak three-dimensionality of the flow around a slender cylinder is considered and the related model, the so-called Ginzburg-Landau equation, is here obtained as an asymptotic solution of the 3D (discrete) Navier-Stokes equation. The derivation is in line with existing slender bodies theories, as the Lifting Line Theory, for example, where the

4. Dinamica não linear e interações de defeitos topologicos e solitons na presença de forças externas e impurezas
We study the catastrophes that can occur in kink dynamics in the presence of external forces and impurities. Under the action of some anharmonic forces it can occurs that not only the translational mode is unstable but also the internal modes ( shape modes) or even part of the continuum spectrum ( the soliton is unstable against the interaction with phonons!
