1. Flutuações do campo eletromagnético no regime de transparência eletromagneticamente induzida / Electromagnetic field fluctuations an electromagnetically induced transparency
A Transparência Eletromagneticamente Induzida tem sido muito usada atualmente para implementação de memórias quânticas. Neste trabalho, estudamos este fenômeno, experimental e teoricamente, utilizando um sistema de dois níveis com degenerescências como modelo para o átomo. Tratamos o campo eletromagnético como quantizado e propomos um modelo linear

2. New theoretical and observational results on transverse magnetic fluctuations near the magnetopause
Electromagnetic ion cyclotron waves in the plasma depletion layer measured by Wind on three inbound passes of the magnetosheath near the stagnation streamline are modeled using theoretical results from Gnavi et al., J. Geophys. Res., 105, 20973, 2000. The kinetic dispersion relation in a plasma composed of electrons, protons, and alpha particles, is solved w

3. Ordem e caos em plasmas magnetizados
The objective of this thesis is to present a clear understanding of some important nonlinear phenomena that are common in space and laboratory plasmas. Specifically,the present analytical and numerical studies have focused on the properties of electromagnetic turbulence as well as associated coherent structures and chaotic behaviors in a multi-component magn

4. Efeitos de flutuação do campo magnetico no interferometro de Stern-Gerlach
Spin coherence experiments with particle beams under magnetic fields are investigated taking into account uncontrollable fluctuations. At the same time specific sources for those fluctuations are pointed in terms of characteristic parameters of experimental apparatus. Two kind of fluctuations sources are analyzed: quantum electromagnetic field thermal fluctu
