Ondas de spin em paredes de domínio unidimensionais em monocamadas magnéticas
(Universidade Federal de São Carlos, 2012-08-16)
Recent investigations on ferromagnetic monolayers predict the existence of spinwave modes without gap in the spectrum, even in the presence of anisotropy. These excitations propagate within the domain walls that exist in ...
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 ...
Termodinâmica de modelos integráveis
(Universidade Federal de São Carlos, 2014-01-20)
In this work we study the thermodynamics of integrable spin chains, like the Heisenberg model and it's spin-s generalization with competing interactions. We have used the quantum transfer matrix approach and obtained a ...
Processamento e propriedades do sistema ferroelétrico (Li,K,Na)(Nb,Ta)O3 dopado com CuO
(Universidade Federal de São Carlos, 2015-03-09)
The search for new lead-free piezoelectric materials has been a major goal of many scientists in recent years. The main cause is the replacement of widely used lead zirconate titanate (PZT) based ceramics due to the highly ...
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, ...
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 ...
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
(Universidade Federal de São Carlos, 2015-04-16)
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 ...
