Um modelo consistente para o processo de fotocontagem contínua e medidas de emaranhamento de sistemas quânticos de variáveis contínuas.
(Universidade Federal de São Carlos, 2005-02-10)
This dissertation embraces two trends of research in modern quantum optics. The first of
them is connected to the photodetection theory, particularly to the continuous measurement
theory developed by Srinivas and Davies ...
Espectroscopia Mössbauer aplicada ao estudo da liga aço baixo carbono-Al nitretada.
(Universidade Federal de São Carlos, 2005-03-18)
We presented in this work a study of the influence of the thickness of Al thin film
deposited in substratum of low carbon steel. Alloys of steel low carbon and
aluminum are used broadly in automobile and aerospace industries. ...
Abordagem via integrais de trajetória do processo de troca e dissipação de energia num sistema composto por dois osciladores harmônicos dissipativos acoplados - o modelo duplicado de Caldeira & Leggett.
(Universidade Federal de São Carlos, 2005-03-11)
In this work, we analyse the dissipation and interchange of energy in a
system composed by two harmonic oscillators, each one associated with a thermal
reservoir.
To this end, we employ the Caldeira & Leggett approach, ...
Solução de um modelo de vértices assimétrico de três estados.
(Universidade Federal de São Carlos, 2005-03-29)
In this work we first review some of the techniques relevant to the theory of two-dimensional integrable models. We apply the Quantum Inverse Scattering approach to a class of three-state vertex model with both closed and ...
Estudos por espectroscopia Raman da heteroestrutura semicondutora InxGa1-xP/GaAs.
(Universidade Federal de São Carlos, 2005-03-24)
In this work, the technique Raman spectroscopy is used in order to study
InxGa1-xP films grown with different thickness on GaAs (001). Two sets of samples grown
by CBE (Chemical Beam Epitaxy) were analized: the first a ...
Influência de solutos intersticiais em nióbio e ligas nióbio-zircônio.
(Universidade Federal de São Carlos, 2005-07-20)
Metals of body-centered cubic structure that contain heavy interstitial solutes, such as oxygen
and nitrogen in solid solution, present anelastic relaxation peaks when submitted to cyclic tensions,
due to the process called ...
