O efeito Zeno no controle da evolução adiabática de um sistema quântico a partir de medidas não-seletivas
(Universidade Federal de São Carlos, 2022-07-26)
The objective of the present work is to improve the performance of a Stimulated Raman Adiabatic Passage (STIRAP) in a 3-level system by applying successive non-selective measurements throughout the evolution (exploiting ...
Incompressible energy spectrum in atomic Bose-Einstein condensates: a weak wave turbulence theory approach
(Universidade Federal de São Carlos, 2022-08-25)
Bose-Einstein condensates with their superfluidity property provide an interesting parallel to classical fluids. Due to the Kolmogorov spectrum of homogeneous turbulence the statistics of the incompressible velocity field ...

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. ...
Electromagnetically induced transparency under effects of light-mediated interactions, entanglement generation, and Fock states detection
(Universidade Federal de São Carlos, 2022-10-25)
This thesis presents a brief compilation of the works developed during my doctorate, and can be divided basically into three main parts. In the first one, we show the changes caused by considering long-range interactions ...
Theoretical and experimental investigation on the visible-light controlled functional properties in charged domain wall ferroelectrics
(Universidade Federal de São Carlos, 2023-04-13)
Optical control of ferroelectric properties have been attracted a growing interest as an
alternative to the conventional control by applied electric fields. However, the major
drawback for achieving an effective reversible ...
Relaxação de spin em nanoestruturas semicondutoras 0 e 2D
(Universidade Federal de São Carlos, 2023-03-01)
This thesis contains a compilation of the work developed and is divided into
three main parts. The first part describes the homogeneous and inhomogeneous
decoherence mechanisms of excitons in GaAs/AlGaAs quantum wells. ...
Electromigration of multiterminal transport bridges
(Universidade Federal de São Carlos, 2023-03-09)
With the continued miniaturization of integrated circuits (ICs), the case of metallic tracks subjected to stress caused by transport currents has become a matter of increasing concern, as it puts at risk the reliability ...
Estudos in sı́lico de proteı́nas alostéricas e sua interação com ligantes
(Universidade Federal de São Carlos, 2023-02-24)
Allosteric proteins are extremely important for the regulation of several functions in
the organism, such as the transport of molecules through the blood and cell membranes,
as well as the phosphorylation of other proteins. ...
Modelos de branas em (5+1) dimensões e o espectro dos leptóns carregados
(Universidade Federal de São Carlos, 2023-10-27)
This manuscript is concerned with a mechanism for explaining the mass spectrum of
the charged leptons within (5 + 1)-dimensional braneworlds. As a preliminary objective,
new two co-dimensional thick braneworlds ought to ...
