Armadilha Óptica de Dipolo para 88Sr
(Universidade Federal de São Carlos, 2019-02-28)
In this work, we present the study of light and matter interaction through the building and operation of a cold atoms experiment. The motivation is to study light scattering in the dense regime, where this phenomenon becomes ...
Propriedades óticas e magneto-óticas de monocamadas de MoWSe2
(Universidade Federal de São Carlos, 2023-01-23)
Two-dimensional (2D) semiconductors, such as transition-metal dichalcogenide (TMD) monolayers, have attracted intense interest in the last years because of their direct band gaps, valley properties and excitonic effects. ...
Quantum transistor using superconducting qubits
(Universidade Federal de São Carlos, 2022-09-23)
In recent times, quantum computation has become a flourishing field of research with increasing investment due to its promise to revolutionize computing, increasing the speed of information processing to levels far beyond ...
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 ...
Propriedades eletrônicas de nanofios semicondutores de Fosfeto de Zinco (Zn3P2)
(Universidade Federal de São Carlos, 2018-04-20)
Zinc phosphide Zn3P2 nanowires with excellent crystalline quality were grown using the Vapor-Liquid-Solid (VLS) method with gold nanoparticles as catalysts. Single nanowire based devices were fabricated with ohmic nickel ...
Turbulência de Ondas em condensados de Bose-Einstein
(Universidade Federal de São Carlos, 2018-02-19)
In this work we used as a starting point the theory developed by Zakharov and Nazarenko for treating wave turbulence in systems
with weak non linearity such as atomic Bose-Einstein condensates with low enough temperature ...
Resposta óptica de sistemas atômicos no espaço livre ou aprisionados dentro de cavidades ópticas no regime de armadilhamento coerente de populações
(Universidade Federal de São Carlos, 2018-02-28)
The aim of this work is to study the electromagnetically induced transparency (EIT) and
the coherent population trapping (CPT) phenomena in three-level systems, such as atoms
and quantum dot molecules (QDM). The present ...
Dependência da anisotropia magnética efetiva em função da temperatura e concentração de níquel de amostras nanoparticuladas de NixCo1-xFe2O4
(Universidade Federal de São Carlos, 2018-03-07)
The study of nanoparticles has generated great interest in recent years in several areas of research. For example, multiferroic composite magnetoelectric materials, in which ferromagnetism and ferroelectricity occur ...
Termodinâmica de buracos negros de Schwarzschild
(Universidade Federal de São Carlos, 2018-05-28)
This dissertation consists of a review about some aspects of Schwarzschild black hole thermodynamics and includes a discussion related to the temporal evolution of the masses of these black holes in a thermodynamic context. ...
