Estados parcialmente emaranhados em comunicação quântica
(Universidade Federal de São Carlos, 2012-03-16)
In this master s thesis we approach the entanglement between quantum states as a resource to be used in the transmission of quantum information, particularly in quantum teleportation. Our focus was directed toward the study ...
Fabricação e caracterização de dispositivos baseados em nanofitas de Óxido de Estanho (SnO2)
(Universidade Federal de São Carlos, 2012-08-06)
The structural and transport features of tin oxide nanobelts synthesized by the vapor-solid method combined with the carbothermal reduction process were investigated in this work. The samples synthesized were characterized ...
Uso de recursos estimuladores da aprendizagem significativa no ensino de física
(Universidade Federal de São Carlos, 2012-07-30)
This research deals with resources which lead to significant learning consistent with the needs of modern society and encourages students to develop knowledge in Physics, in order to enable them to interact with the community ...
Caracterização das propriedades ópticas e de spin de poços quânticos de InGaAsN/GaAs
(Universidade Federal de São Carlos, 2015-03-30)
In this work, it was investigated the optical and magneto-optical properties of In- GaAsN/GaAs and InGaAs/GaAs double quantum wells. It was performed a systematic experimental study of photoluminescence (PL) as a function ...
Estudo do modo coletivo massivo do líquido de Fermi ferromagnético
(Universidade Federal de São Carlos, 2014-02-25)
The present dissertation is divided in 4 chapters. From chapter 1 to 2, we review some basic concepts of the normal Fermi liquid theory (a set of interacting fermions in correspondence with the Fermi gas) such as quasiparticles, ...
Estudo de ondas viajantes não lineares de perfil saturado
(Universidade Federal de São Carlos, 2013-04-29)
In this paper, we study a class of nonlinear waves in one dimension using the assumption of traveling waves. First we found the solutions to the partial differential equation (PDE) containing a term of nonlinear inhomogeneity, ...
Superposição de estados comprimidos de dois modos e aplicações em informação quântica
(Universidade Federal de São Carlos, 2019-03-07)
In this work, we present a new class of quantum states for applications in quantum
metrology and quantum information, the states here named as “Even EPR” and “Odd
EPR”. We present a review of the basic concepts of ...
Magneto luminescência em diodos de tunelamento ressonante contendo pontos quânticos de InAs
(Universidade Federal de São Carlos, 2011-03-15)
In this work, we have studied the spin polarization of carriers in n-type resonant tunneling diodes (RTDs) of GaAs/AlGaAs which incorporates a single layer of InAs selfassembled quantum dots in the center of the GaAs quantum ...
Experimentos em ondas e acústica para auxiliar o processo ensino e aprendizagem da física no ensino médio
(Universidade Federal de São Carlos, 2012-04-13)
This paper describes the development of experimental activities with the aid of the microcomputer as a measuring tool in the laboratory teaching of physics, as well as an account of his experience in the classroom. Using ...
Ondas gravitacionais e o espectro de anisotropia tensorial na presença de neutrinos cosmológicos
(Universidade Federal de São Carlos, 2012-07-10)
In this work we have studied the evolution of primordial gravitational waves coupled to anisotropic stress tensor of cosmological neutrinos. As in a radiation dominated universe, in a universe dominated by radiation and ...
