Caracterização magnética de compósitos multiferróicos particulados Pb(Zr0,52Ti0,48)O4/CoFe2O4
(Universidade Federal de São Carlos, 2014-08-26)
This work was studied the magnetic and electrical properties of particulate multiferroic composite Pb (Zr0,52Ti0,48) O4 / CoFe2O4 (PZT / CFO) (0-3 type) prepared by the polymeric method of Pechini and sintered by ultra-rapid ...
Termalização de qubits sujeitos à ação de reservatórios coletivos markovianos
(Universidade Federal de São Carlos, 2014-08-26)
We are interested in understanding the process of Markovian thermalization in quantum systems when we have one or two qubits interacting with a quantum electromagnetic field mode, using the Rabi model, in situations where ...
Quantum memory based on electromagnetically induced transparency in optical cavities

Espectroscopia Mössbauer : condições experimentais de aquisição e estocagem multicanal para a análise numérica de dados com adequação de resolução espectral
(Universidade Federal de São Carlos, 2012-02-15)
The objective of this work is to examine the use of Mossbauer spectroscopy in two aspects: the data acquisition, using four different setups and their analysis, comparing three different fittings programs. Concerning to ...
Estados parcialmente emaranhados em comunicação quântica
(Universidade Federal de São Carlos, 2012-03-16)
In this master s thesis we approach the entanglement between quantum states as a resource to be used in the transmission of quantum information, particularly in quantum teleportation. Our focus was directed toward the study ...
Fabricação e caracterização de dispositivos baseados em nanofitas de Óxido de Estanho (SnO2)
(Universidade Federal de São Carlos, 2012-08-06)
The structural and transport features of tin oxide nanobelts synthesized by the vapor-solid method combined with the carbothermal reduction process were investigated in this work. The samples synthesized were characterized ...
Uso de recursos estimuladores da aprendizagem significativa no ensino de física
(Universidade Federal de São Carlos, 2012-07-30)
This research deals with resources which lead to significant learning consistent with the needs of modern society and encourages students to develop knowledge in Physics, in order to enable them to interact with the community ...
Caracterização das propriedades ópticas e de spin de poços quânticos de InGaAsN/GaAs
(Universidade Federal de São Carlos, 2015-03-30)
In this work, it was investigated the optical and magneto-optical properties of In- GaAsN/GaAs and InGaAs/GaAs double quantum wells. It was performed a systematic experimental study of photoluminescence (PL) as a function ...
Estudo do modo coletivo massivo do líquido de Fermi ferromagnético
(Universidade Federal de São Carlos, 2014-02-25)
The present dissertation is divided in 4 chapters. From chapter 1 to 2, we review some basic concepts of the normal Fermi liquid theory (a set of interacting fermions in correspondence with the Fermi gas) such as quasiparticles, ...
Estudo de ondas viajantes não lineares de perfil saturado
(Universidade Federal de São Carlos, 2013-04-29)
In this paper, we study a class of nonlinear waves in one dimension using the assumption of traveling waves. First we found the solutions to the partial differential equation (PDE) containing a term of nonlinear inhomogeneity, ...
