Do positivo ao negativo : utilizando ferramentas computacionais e experimentação para a simulação de (meta)materiais refrativos
(Universidade Federal de São Carlos, 2016-08-22)
This work aims at the development of physical phenomena simulations associated to
mathematical modeling and experimentation. The choice of geometrical optics is due,
among other reasons, to the need for raising the ...
Comportamento termodinâmico de cadeias de dímeros
(Universidade Federal de São Carlos, 2016-10-31)
In this Thesis we propose to describe the thermodynamical properties of dimer chains
in a one-dimensional lattice rstly considering q-states of chain orientation in the lattice
and secondly by a three states model where ...
Estudo comparativo entre duas teorias de perturbação dependentes do tempo em mecânica quântica
(Universidade Federal de São Carlos, 2016-02-25)
This monograph shows two perturbative methods to determine the time evolution of quantum systems described by time-depependent Hamiltonians. One method is the standard time-dependent perturbation theory usually found in ...
Propriedades estruturais e magnéticas do isolante topológico Bi2Se3 com aglomerados de FexSey
(Universidade Federal de São Carlos, 2016-03-29)
In this work, we discuss the growth of Fe containing Bi2 Se3epilayers on the
GaAs(111) substrate by molecular beam epitaxy (MBE) with Fe contents of in the 8-
20% range. It is shown that Bi2 Se3 film thin are grown with ...
Teletransporte quântico na presença de ruído
(Universidade Federal de São Carlos, 2016-04-01)
The main focus of this work is to explore the feasibility of conducting the
teleportation protocol in scenarios where the presence of an external environment
reduces the purity of the input state and the transmission ...
Influência do tamanho médio de grão nas propriedades ferroicas de compósitos magnetoelétricos particulados
(Universidade Federal de São Carlos, 2016-04-08)
In the case of composites materials, which presents the magnetoelectric coupling,
there are so many questions about the influence of the microstructure on the coupled
and uncoupled properties. Thereby, this work proposes ...
Síntese e caracterização de filmes do sistema Zn(1−x)CoxO obtidos por spray pirólise
(Universidade Federal de São Carlos, 2016-03-09)
We report a systematic study on the structural, morphological and optical properties of
Zn1−xCoxO thin films grown by spray pyrolysis. The employed nominal concentrations
were up to 15 Co %. The films were deposited on ...
