Dressed perturbation theory for the quark propagator: Fernando Enrique Serna Algarín. -
(Universidade Estadual Paulista (Unesp), 2013-06-11)
The rainbow-ladder approximation is a simple nonperturbative truncation scheme for nonperturbative calculations in Quantum Chromodynamics (QCD). It provides satisfactory results for the ground-states of light pseudoscalar ...
Equilibrium and Non-Equilibrium in a Reversible and Conservative Cellular Automaton.
(2021-07-28)
The main goal of this thesis, relies the dynamis of a reversible and
conservative cellular automaton Q2R model. Q2R is a automaton that runs on a
two-dimensional grid of nite size and is reversible in a physical sense, ...
Data-driven morphable wing for tracking and mapping using small UAVs
(González Chávez Othón, 2017-04-21)
The arrival of Unmanned Aerial Vehicles into the civil scene, has been a breakthrough in the capabilities of testing new morphing-wing designs. Compared to full-scale, manned aircraft, their low-cost, fast implementation, ...
Transição de fase quântica e modelos de spins frustrados
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2007-03-15)
In this thesis, we will study the quantum phase transition of frustrated quantum spin
models: (i) van Hemmen model ( S = 1) with transverse and anisotropic biaxial field (ii)
Heisenberg model (S = 1/2 ) with competitive ...
Mezclado mecánico de polvos Fe, Ni, Co y su efecto en sus propiedades magnéticas y eléctricas en un material compuesto (M-polímero)
(Universidad Michoacana de San Nicolás de Hidalgo, 2020-01)
In this work, the magnetic and electrical properties of a soft magnetic composite (SMC) material were studied, using low-energy mechanical milling on Fe, Ni and Co metal powders at different mixing times, to promote the ...
Caos e termalização na teoria de Yang-Mills-Higgs em uma rede espacial
(Universidade Estadual Paulista (Unesp), 2009-11-06)
In this thesis, we are dedicated to study the time evolution generated by the hamiltonian of a classical Yang-Mills-Higgs theory with gauge symmetry SU(2) on a spatial lattice. In particular, we study energy transfer and ...
Inducing a topological transition in graphene nanoribbons superlattices by external strain
(Universidad de Chile, 2022)
The purpose of this thesis is to study the existence of localized states in superlattices, which can be used to create nanoelectronic devices.
These ideas are born with the observation of localized states in polyacetylene, ...
