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 ...
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 ...
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 ...
Fabricação e caracterização elétrica de dispositivos orgânicos emissores de luz derivados de poli-p(fenilene vinilene) (PPV)
(Universidade Federal de São Carlos, 2010-03-16)
Molecularly doped polymers have been widely studied in recent years due to their electronic and optical properties, and application in the manufacture of opto-electronic devices, light emitting diodes (LED) and others. ...
Efeitos de localização de portadores em poços quânticos de GaBiAs/GaAs
(Universidade Federal de São Carlos, 2015-08-04)
In order to investigate optical and spin properties of GaBiAs / GaAs quantum
wells, we performed both photoluminescence and magneto-photoluminescence
spectroscopy measurements in three samples: 10 nm quantum wells with ...
Effective-action approach to dirty bosons in optical lattices
(Universidade Federal de São Carlos, 2019-02-21)
A system of cold bosonic atoms loaded in an optical lattice potential can undergo a macroscopic phase transition due to quantum fluctuations. As the depth of the lattice potential is increased, the ground state of the ...
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 ...
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 ...
Obtenção e caracterização de heteroestruturas epitaxiais magnetoelétricas de [KNbO3]0,9-[BaNi1/2Nb1/2O3-𝛿]0,1 e [La0,7Sr0,3MnO3]
(Universidade Federal de São Carlos, 2016-10-07)
Magnetoelectric materials have been extensively studied in the last decade, particularly due to the applicability for sensors, attenuators, transformers and others. Hence as an objective for this work we propose a study ...
Caracterização óptica e magneto-óptica de filmes de GaPN
(Universidade Federal de São Carlos, 2016-09-13)
This project proposes a systematic study of III-V semiconductors, which are promising for integration with silicon. It consists of the characterization of GaPN film samples with different nitrogen concentrations. We ...
