Efeito da modulação da topologia do confinamento em sistemas quase zero-dimensionais induzida por campo elétrico
(Universidade Federal de São Carlos, 2015-04-01)
Quantum dots grown by epitaxial techniques for optical and transport studies are usually capped by a layer of the same material on which the QDs were grown. Recently, several studies have shown how the growth parameters ...
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 ...
Controle coerente da excitação de modos topológicos em condensados de Bose-Einstein
(Universidade Federal de São Carlos, 2019-07-04)
In this project were carried out a study on dynamics control of one dimensional Bose- Einstein condensates of dilute gases by development and application of techniques on systems that are described by Gross-Pitaevskii ...
Anelasticidade em titânio, tântalo e na liga Ti-40Ta
(Universidade Federal de São Carlos, 2014-07-24)
The growing demand for increasingly resistant and biocompatible with the human body implantable materials, has led to an increase in demand for new metallic biomaterials. Some materials, such as titanium and its alloys, ...
Unidades de Ensino Potencialmente Significativas (UEPS)em Ambientes Virtuais de Aprendizagem (AVA) como instrumento de aprendizagem significativa de física no ensino médio
(Universidade Federal de São Carlos, 2013-11-19)
This work uses Potentially Meaningful Teaching Unit (PMTU), the instructional strategy proposed by M. A. Moreira, in a Virtual Learning Environment (VLE) in the Moodle platform, as a tool for learning physics in high school, ...
Propriedades espectroscópicas da ação antimicrobiana do peptídeo polycerradin
(Universidade Federal de São Carlos, 2015-02-03)
The spectroscopy is a technique based on light-matter interaction, which provides information about the composition and structure of molecules. For this reason, it is used in various fields of science, including the biology. ...
Medidas quânticas, descoerência e emaranhamento em cenários de física de neutrinos
(Universidade Federal de São Carlos, 2014-02-11)
In the first part of this work we describe the cosmological neutrinos as a composite quantum system and use the generalized theory of quantum measurements to acquire a probabilistic correlation between observable energies ...
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 ...
Solução numérica das equações de Maxwell para cavidades dielétricas bidimensionais
(Universidade Federal de São Carlos, 2012-08-07)
The objective of this work is to find numerical solutions for Maxwell's equations in two-dimensional dielectric cavities. Such structures can trap light by means of total internal reflections and can be used for constructing ...
Quantum memory based on electromagnetically induced transparency in optical cavities
