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 ...
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 ...

(Universidade Federal de São Carlos, 2017-11-24)
This work consists of investigations of the structural, morphological and optical properties of thin films of the Zn(1-x)Cu(x)O system grown on glass substrate using the Spray-Pyrolysis technique with Zinc and Copper ...
Matrizes de reflexão com simetria 𝒰𝑞 [osp(2|2𝑚)(2)]
(Universidade Federal de São Carlos, 2012-03-16)
In this thesis we present solutions of the graded boundary YANG-BAXTER equations for vertex models with 𝒰𝑞 [osp(2|2𝑚)(2)] symmethy.
Estudo da viabilidade de equipamento LIBS-LIF contínuo para aumento do limite de detecção do mercúrio
(Universidade Federal de São Carlos, 2017-09-22)
This work aims to verify the feasibility of a continuous LIBS-LIF equipment construction at 405 nm for heavy metals analysis, focusing on mercury. We have studied experimentally a diode laser of a continuous light source ...
Efeitos do campo magnético sobre processos de corrosão em aço AISI 1020
(Universidade Federal de São Carlos, 2017-09-19)
In this dissertation the effects of the application of magnetic field during the electrochemical reactions of corrosion in samples of steel AISI 1020 in KNO_3 solution were investigated. The experiments were measurements ...
Geração de corrente spin polarizada em heteroestruturas dopadas com impurezas magnéticas
(Universidade Federal de São Carlos, 2015-08-07)
In this dissertation, the computational modeling of two semiconductor structures composed of two quantum wells was performed, being a quantum well doped with magnetic impurities. Each structure was designed to form a ...
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 ...
Superposição de estados comprimidos de dois modos e aplicações em informação quântica
(Universidade Federal de São Carlos, 2019-03-07)
In this work, we present a new class of quantum states for applications in quantum
metrology and quantum information, the states here named as “Even EPR” and “Odd
EPR”. We present a review of the basic concepts of ...
Estudo de algoritmos para a determinação da temperatura de fusão
(Universidade Federal de São Carlos, 2015-08-31)
In this work, we studied the main methods used in molecular dynamics simulations to obtain the melting temperature of crystalline materials. The methods evaluated were the solid-liquid coexistence, mechanical melt of bulk, ...
