Obtenção e caracterização de perovskitas supercondutoras monocristalinas do tipo YxPr1-xBa2Cu3O7-δ dopadas por Fe, Ni, Ga e Zn
(Universidade Federal de São Carlos, 2009-04-30)
The Praseodymium is known to have a singular behavior in the family of cuprate superconductors of high critical temperature of the type RE-123. When these cuprates are doped with Praseodymium apparently critical temperature ...
Transporte dependente de spin em nanofios semicondutores controlado via interação spin-órbita
(Universidade Federal de São Carlos, 2019-04-26)
This work was dedicated to the theoretical study of semiconductor nanostructures aimed at the implementation of spin dependent electronic transport. The objective was to study the electron transport properties considering ...
Uma introdução à invariância conforme na Teoria das Cordas
(Universidade Federal de São Carlos, 2018-10-11)
In this work we study the formalism of Conformal Field Theory (CFT) and apply it to the theory of strings and superstrings. We also use the BRST quantization technique to obtain the string spectrum together with the ...
Formação de moléculas diatômicas heteronucleares utilizando pulsos de laser com frequência dependente do tempo
(Universidade Federal de São Carlos, 2019-02-15)
In this work, we consider the formation and vibrational stabilization of cold hetero-
nuclear molecules using infrared nanosecond pulses. Starting with a pair of coliding cold
atoms of dissimilar species, we aim to form ...
Equação mestra microscópica para o modelo de Rabi
(Universidade Federal de São Carlos, 2013-02-27)
The Rabi model is the most complete one has to describe the interaction between radiation and matter. However, as it is difficult to obtain the exact solution to this model, many of recent atom-field studies have used the ...
Transparência eletromagneticamente induzida em diferentes sistemas físicos e seu análogo em osciladores acoplados
(Universidade Federal de São Carlos, 2013-08-01)
The simultaneously incidence of two light beams on one or more atoms causes destructive interference of these beams in atomic states causing cancellation of the absorption of one of the incident beams and this phenomenon ...
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 ...
Inibição enzimática analisada com uma abordagem da mecânica estatística
(Universidade Federal de São Carlos, 2019-02-21)
In the conventional approach of Biochemistry, a parameter for the description of the functioning of an enzyme is the rate of conversion of substrate into product in the presence or absence of an inhibitor. Given this ...
Síntese e caracterização de nanopartículas de óxido de ferro e de grafite magnética fluida (GMF)
(Universidade Federal de São Carlos, 2008-09-05)
In this work were studied the physical properties of magnetic nanoparticles, based on iron oxide, and magnetic graphite fluid particles. The work was developed in three steps: 1) synthesis of the magnetic nanoparticles of ...
Construção e caracterização do campo acústico de transdutores ultra-sônico piezoelétrico de polarização variável
(Universidade Federal de São Carlos, 2008-10-23)
This work was motivated on the great technological and commercial interest of ultrasonic transducer, capable to generate diffraction controlled ultrasonic beams in the
frequency range of kHz up to MHz. As a solution, in ...
