Blockade and antiblockade effects with near-ground state neutral atoms
(Universidade Federal de São Carlos, 2022-09-06)
In this work we study the photon blockade and antiblockade effects in a system of neutral
atoms with a two-level structure, in the limit where induced dipole-dipole interactions
mediated by light are relevant. Such system ...
Efeitos de dimensionalidade em perovskitas de haletos para aplicações em células solares: um estudo ab initio
(Universidade Federal de São Carlos, 2022-10-07)
The structural stability and toxic lead are known obstacles to the current photovoltaic application of perovskite solar cells (PSCs) with high power conversion efficiencies (PCEs). Herein, we perform a systematic study ...
Método de dinâmicas efetivas aplicado na análise da interação qubit-qubit em dispositivos supercondutores: a interação qubit-qubit no contexto da computação quântica
(Universidade Federal de São Carlos, 2022-02-23)
In this dissertation, we approach some aspects of quantum computing. At first, we detail the Deutsch-Jozsa algorithm and show how to implement it in real IBM quantum computers, available free of charge via remote access ...
Estudo das propriedades ópticas de filmes finos e poços quânticos de GaAsPN/GaPN
(Universidade Federal de São Carlos, 2016-09-08)
Diluted nitride III-V semiconductor leagues have physical properties that make them
interesting for applications on optoelectronic devices. The possibility to lattice matching
GaAsPN with silicon makes this semiconductor ...
Estudos por espectroscopia Raman da heteroestrutura semicondutora InxGa1-xP/GaAs.
(Universidade Federal de São Carlos, 2005-03-24)
In this work, the technique Raman spectroscopy is used in order to study
InxGa1-xP films grown with different thickness on GaAs (001). Two sets of samples grown
by CBE (Chemical Beam Epitaxy) were analized: the first a ...
Influência de solutos intersticiais em nióbio e ligas nióbio-zircônio.
(Universidade Federal de São Carlos, 2005-07-20)
Metals of body-centered cubic structure that contain heavy interstitial solutes, such as oxygen
and nitrogen in solid solution, present anelastic relaxation peaks when submitted to cyclic tensions,
due to the process called ...
Engenharia de interações fônon-fóton-matéria mediadas por um campo clássico.
(Universidade Federal de São Carlos, 2004-04-30)
In this work we consider the problem of a three-level trapped ion inside a high-
Q cavity. We study the process of phonon-foton-matter interaction mediated by a
classical field. We are particularly interested in the ...
O estudo do limite de transporte interfilamentar de supercorrentes em amostras supercondutoras de BSCCO.
(Universidade Federal de São Carlos, 2006-03-15)
In this work, we have studied the behavior of the line H*(T) in filamentary samples of BSCCO, which were grown by the LFZ technique, Laser Floating Zone. Previously studied in other specimens prepared by specific routes ...
Estudo de efeitos quânticos nas propriedades eletrônicas de nanofios semicondutores
(Universidade Federal de São Carlos, 2010-03-02)
The growth and characterization of semiconductor nanowires systems have attracted increasing interest due to their potential technological application, like, photo-detectors, optoelectronic devices and their promising ...
Geração e proteção de estados comprimidos do campo e estados atômicos emaranhados em cavidades ópticas
(Universidade Federal de São Carlos, 2010-03-03)
In this work we investigated the engineering of interactions and reservoirs in the context of Cavity Quantum Electrodynamics. The investigated system consists of two identical three-level atoms trapped in two distinct ...
