Theoretical studies of magnetic materials at the micrometer and nanometer scale
(2005)
In this thesis we analyzed, from a theoretical point of view, different aspects of the magnetic system at the micrometer and nanometer scale. Firstly, we studied the
applications of the magnetostatic of continuous media ...
Soft thermal contributions to 3-loop gauge coupling
(2018)
We analyze 3-loop contributions to the gauge coupling felt by ultrasoft ("magnetostatic") modes in hot Yang-Mills theory. So-called soft/hard terms, originating from dimension-six operators within the soft effective theory, ...
Approximated solutions to Born-Infeld dynamics
(Springer, 2016-02-01)
The Born-Infeld equation in the plane is usefully captured in complex language. The general exact solution can be written as a combination of holomorphic and antiholomorphic functions. However, this solution only expresses ...
Aprendizagem e busca local em algoritmos meméticos para projetoassistido por computador
(Universidade Federal de Minas GeraisUFMG, 2008-02-29)
The computer aided design (CAD) process is an automated system characterized by the association of a mathematical and computational model of the device being designed and an adequate automatic search technique, an optimization ...
Aspectos Clássicos da Eletrodinâmica de Podolsky
(Universidade Estadual Paulista (Unesp), 2014-04-29)
The Generalized Electrodynamics was developed by Boris Podolsky in 1942 and it is a generalization of Maxwell’s theory where Podolsky added a new term to the Maxwell’s Lagrangean with a second derivative of the electromagnetic ...

Bifunctional CoFe2O4/ZnO Core/Shell Nanoparticles for Magnetic Fluid Hyperthermia with Controlled Optical Response
(American Chemical Society, 2018-02-23)
Conjugation of optical and magnetic responses in a unique system at the nanoscale emerges as a powerful tool for several applications. Here, we fabricated bifunctional CoFe2O4-core/ZnO-shell nanoparticles with simultaneous ...
