Imageamento magneto-ótico quantitativo em filmes finos supercondutores bicamada e com gradiente nanométrico de espessura
(Universidade Federal de São Carlos, 2019-12-11)
Vortex matter in superconductors has been the focus of research of both theoretical and experimental groups around the world.
When developing superconducting devices patterned on thin films one should bear in mind that ...
Magnetismo d0 em óxidos de In2O3 e (Sn1-xCex)O2
(Universidade Federal de São Carlos, 2019-05-02)
We investigated the structural, optical and magnetic properties of two nanoparticles oxide systems: In2O3, prepared by the high energy mechanical milling process, and (Sn1-xCex)O2 produced by the Pechini method, using ...
Comunicação quântica baseada no teletransporte em variáveis contínuas
(Universidade Federal de São Carlos, 2014-12-12)
In this Thesis we study in details one of the most astonishing application of quantum mechanics which totally departs from our common sense: quantum teleportation in continuous variables. We present a review of the postulates ...
Processamento e caracterização de compósitos laminados de La0.7Ba0.3MnO3/BaTiO3
(Universidade Federal de São Carlos, 2015-02-13)
Multiferroic laminated ceramic composites consisting of piezoelectric (BaTiO3, phase B) and magnetostrictive (Lao.7Bao.3MnO3, phase L) materials were synthesized by the Pechini and solid state reaction (SSR) method. Barium ...
Magneto hipertermia in vitro em células hek293t utilizando nanopartículas de óxido de ferro magnéticas com diferentes recobrimentos
(Universidade Federal de São Carlos, 2017-08-03)
One of the largest challenges on medicine has been developing treatments for several types of cancer. Moreover, conventional treatments for cancer such as chemotherapy and radiotherapy have been presenting undesirable ...
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 ...
Importância dos efeitos de absorção no espalhamento elástico de elétrons por moléculas
(Universidade Federal de São Carlos, 2017-03-11)
In this work we study the importance of absorption effects on the electron-molecule interaction dynamics. These effects are simulated by a complex optical model potential from which the imaginary part is an absorption ...
Contraste entre propriedades optoeletrônicas em estruturas de tunelamento ressonante n-i-n baseadas em GaAs
(Universidade Federal de São Carlos, 2019-05-15)
Resonant Tunneling Diodes (RTDs) are semiconductor devices usually composed of two barrier structures embedding a single quantum well (QW) and highly doped layers in its extremities. Under an applied bias voltage, the ...
Investigação das propriedades magnetoelásticas da ferrita de níquel : análise teórico-experimental
(Universidade Federal de São Carlos, 2018-02-21)
In this dissertation, we investigate the magnetoelastic properties of nickel ferrite compared
to the pure metal nickel, either by ab-initio calculation or through experiments using the
capactive cell technique. The first ...
Controle das propriedades estatísticas do campo e biestabilidade óptica em eletrodinâmica quântica de cavidades
(Universidade Federal de São Carlos, 2013-03-27)
We investigate in this thesis the control of absorptive optical bistability in a standing wave optical cavity filled with a collection of two and three-level noninteracting atoms weakly coupled to a single electromagnetic ...
