1. Estudo e geração de estados não clássicos em nanocircuitos: propriedades e aplicações / Study and generation of nonclassical states in nanocircuits: properties and aplications
In this work we used an arrangement consisting of Cooper pairs (Cooper Pair Box, CPB) interacting with a nanomechanical Resonator (NR) for various studies: to produce controlable holes in the statistical distribution of excitations of the NR, for resonant and non-resonant cases; to study the evolution of the entropy and the inversion of excitations, includin

2. Modelagem da propagação não linear em fibras opticas : sistemas de transmissão de dados e amplificadores / Modeling non linear propagation in optical fibers : data transmission systems and optical parametric amplifiers
We introduce optimized models and algorithms for the simulation of non linear propagation in optical fibers using the split-step Fourier Method (SSFM). Dispersion and the Kerr effect are the two main effects considered in the simulations. We study the coupled equations, considering both polarization modes, as well as the scalar equation, which can be applied

3. Existencia e multiplicidade de soluções para a Equação de Schrodinger não-linear em Rn / Existence and multiplicity of solutions for the non-linear Schrodinger Equation in Rn
In this dissertation we get resulted of multiplicity of not trivial weak solutions for the problem -Du + V (x)u = f (x; u); x 2 RN; where V is continuous, f is C1, with f (x; 0) = 0 and f is asymptotically linear. We use variationals methods and the theory of critical groups, to get and to distinguish the solutions. We also present results of existence of no
