Método de dinâmicas efetivas aplicado na análise da interação qubit-qubit em dispositivos supercondutores: a interação qubit-qubit no contexto da computação quântica
(Universidade Federal de São Carlos, 2022-02-23)
In this dissertation, we approach some aspects of quantum computing. At first, we detail the Deutsch-Jozsa algorithm and show how to implement it in real IBM quantum computers, available free of charge via remote access ...
Dopagem substitucional de peroviskitas com metais de transição 3d: um estudo ab initio
(Universidade Federal de São Carlos, 2022-10-04)
The global demand for energy has brought into focus the halide perovskites as materials
with high potential for applications in photovoltaic devices. Great progress has been made
in the last 10 years, demonstrating the ...
Otimizando a eficiência de células solares baseadas em nanoestruturas semicondutoras quaternárias
(Universidade Federal de São Carlos, 2020-02-28)
Solar cells composed of semiconductor materials with gap energies and different structures, commonly known as Multijunction, have been the record holders for efficiency in converting solar to electric energy in recent ...
Separação espacial de fases no modelo de seis vértices
(Universidade Federal de São Carlos, 2020-01-14)
In this work, we have studied the six-vertex model with domain wall and reflecting end boundary conditions, focusing mainly on the influence of boundary conditions on the thermodynamic limit. In order to find a complete ...
Development of a stable diode laser system for cavity-assisted matter-wave interferometry
(Universidade Federal de São Carlos, 2020-08-27)
The project is part of an experiment that has been developed to probe the dynamics of ultracold strontium atoms in a vertical one-dimensional optical lattice sustained by a ring cavity. A fundamental part of the experiment ...
Deposição e caracterização de filmes finos do sistema Zn(1-x)CoxO obtidos por spray pirólise para aplicação em sensor de ozônio
(Universidade Federal de São Carlos, 2021-04-19)
The current concern about reducing the harmful effects of air pollution on environment and human health requires adequate gas sensors that allow an efficient control and monitoring on a wide range of pollutants. This ...
Propriedades ópticas de filmes semicondutores GaAsBi e GaSbBi
(Universidade Federal de São Carlos, 2022-05-02)
Bismuth-diluted III-V are interesting materials for possible applications in optoeletronic and spintronic devices. If we add a small amount of Bi in III-V materials, we observe a strong reduction in the band gap energy. ...
Raman spectroscopy as a reliable tool for strain analysis in iii-nitride superlattices
(Universidade Federal de São Carlos, 2021-09-02)
Since its discovery, the Raman effect has been a great ally in the structural investigation of a wide variety of materials, from macro to nanoscale. However, despite the remarkable sensitivity of techniques based on Raman ...
Engenharia de reservatórios com temperaturas efetivas arbitrárias e máquinas térmicas quânticas para sistemas de spins nucleares
(Universidade Federal de São Carlos, 2021-05-24)
In this work we show how to engineer reservoirs with different effective temperatures for a single qubit (quantum bit) system. To that end, we built an appropriate interaction between a qubit, that is, a 13C nuclear spin, ...
Propriedades óticas e elétricas de dicalcogenetos de metais de transição sobre talco
(Universidade Federal de São Carlos, 2022-02-24)
Two-dimensional (2D) systems have attracted great attention in the last years, for
fundamental physics and in potential applications as optoelectronic devices. There is a great interest in transition metal dichalcogenides ...
