Simulação por dinâmica molecular de óxidos alcalino-terrosos
(Universidade Federal de São Carlos, 2006-05-04)
The main subject of this work is to simulate structural and dynamical properties
of MeO type alkaline-earth oxides, where Me is an element of the family 2 (Me = Ca,
Sr and Ba). The use of the Molecular Dynamics method (MD) ...
Origem dos momentos magnéticos localizados em ligas de cromo com metais de transição por oscilações de Friedel
(Universidade Federal de São Carlos, 2006-08-02)
The fundamental magnetic properties of chromium and its alloys Cr(1¡x)Nb(x) and Cr(1¡x)V(x), were investigated with the aim to achieve a better comprehension about the nature of the spin density waves. Was dened the edge ...
O estudo do limite de transporte interfilamentar de supercorrentes em amostras supercondutoras de BSCCO.
(Universidade Federal de São Carlos, 2006-03-15)
In this work, we have studied the behavior of the line H*(T) in filamentary samples of BSCCO, which were grown by the LFZ technique, Laser Floating Zone. Previously studied in other specimens prepared by specific routes ...
Monitoramento de propriedades de condensados de Bose-Einstein interagindo não ressonantemente com campos óticos via detecção contínua de fotóns
(Universidade Federal de São Carlos, 2006-03-13)
In this work we consider an of - resonant interaction between optical fields and a Bose - Einstein condensation. We used a continuous photo detection model to study the efects of the counting of k photons of the optical ...
Processos de relaxação em sistemas quânticos e álgebra de operadores não-lineares
(Universidade Federal de São Carlos, 2006-02-24)
On this thesis some aspects of relaxation processes and decoherence processes using deformed
algebras of the harmonic oscillator, particularly the generalized deformed algebra (GDA algebra)
and Kerr algebra were studied.Two ...
Modelos magnéticos com frustração e diluição
(Universidade Federal de São Carlos, 2006-12-08)
In this work, we investigate the effect of dilution and frustration in the thermodynamic properties and the phase diagrams using the quasi-two-dimensional Heisenberg and Ising models. We use the Zubarev Green´s function ...
Transdutores ultra-sônicos piezoelétricos com difração limitada : simulação e construção
(Universidade Federal de São Carlos, 2006-08-18)
The importance of ultrasound limited-diffraction Bessel beams in medical
images, tissue characterization, and estimation of Doppler speed (blood flow) as
well as in many other areas of Physics has increased in the two ...
Processamento e caracterização de cerâmicas eletro-ópticas do sistema ferroelétrico (Pb1-xLax)TiO3
(Universidade Federal de São Carlos, 2006-08-04)
The ferroelectric titanate of lead modified with Lanthanum metal system (or PLT) is the most studied of the perovskite structure. It is known that ceramic bodies with specify compositions and adequately chemical preparations ...
