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 ...
Relações estrutura: propriedades como subsídio à elucidação do diagrama de fases do sistema ferroelétrico (Pb,Ca)TiO3
(Universidade Federal de São Carlos, 2013-02-28)
Solid solutions with perovskite structure, especially lead-based oxides, have been developed and investigated as single crystal and/or polycrystal ceramics since the midtwentieth century, but aspects of phase diagram of ...
Curvas de rotação galácticas em teorias métricas da gravitação
(Universidade Federal de São Carlos, 2019-04-01)
From a Parametrized Post-Newtonian (PNP) perspective we attempt to partially answer
the question, by studying some models, of whether or not the new degrees of freedom,
represented by the PNP potentials, can lead to ...
Efeitos de parâmetros de crescimento nas propriedades ópticas de filmes finos de ZnO:Er
(Universidade Federal de São Carlos, 2019-12-19)
We report a systematic study on the structural, morphological and optical properties of Er-doped ZnO thin films grown by Spray Pyrolysis. The films were deposited on glass substrates between 230ºC - 300ºC, using as precursors ...
Coerência espectral da luz espalhada por átomos frios saturados
(Universidade Federal de São Carlos, 2020-02-27)
The spectrum of radiation resonantly scattered by a strongly-driven two-level system consists of three peaks called the Mollow’s triplet. In the case of cold atoms, we can approximate their energy level structure by a ...
Modelo de Anderson com repulsão coulombiana nos níveis que se acoplam com o ponto quântico
(Universidade Federal de São Carlos, 2019-12-20)
In this work, a study of the Anderson model is done for the case of a quantum dot between
two electron gases, single-electron transistor (SET), where a Coulombian repulsion term
was added at the orbitals that are directly ...
