Influência da geometria de anéis para geração de campos magnéticos inomogêneos em dispositivos supercondutores
(Universidade Federal de São Carlos, UFSCar, , Câmpus São Carlos, 06/04/2023)Conducting materials transport electric currents very effectively due to their low resistivity. A conductor's electric current distribution induces a magnetic field around it, which the Ampère-Maxwell Law can describe. On ... -
Introdução ao estudo dos buracos negros na relatividade geral
(Universidade Federal de São Carlos, UFSCar, , Câmpus São Carlos, 28/04/2022)This monograph arose from the author's interest in understanding one of the most exotic objects of study in Physics: black holes. With this in mind, this work aimed to introduce the study of black holes in the context of ... -
Autogravitação para espaços-tempos estáticos e isotrópicos com aplicações a modelos de interesse astrofísico
(Universidade Federal de São Carlos, UFSCar, , Câmpus São Carlos, 24/11/2012)In this work I consider the equations of self-gravitation for collisionless, static and isotropic systems in the context of the theory of general relativity. From these I present the form of the distribution function when ... -
A formulação de Eisenhart para teorias de campos escalares
(Universidade Federal de São Carlos, UFSCar, , Câmpus São Carlos, 30/09/2022)In the present work, we discuss the Eisenhart lift, introduced by L. P. Eisenhart in 1928, when dealing with analytical mechanics. The core idea behind the lift is to look at a lagrangian mechanical or field system that ... -
Simulações de Monte Carlo para estudar a propagação da luz através da pele de diferentes fototipos
(Universidade Federal de São Carlos, UFSCar, , Câmpus São Carlos, 26/11/2021)In the last years, there has been an increase in interest in using light as a treatment, and it has been shown that this is a great alternative to more traditional treatments. Due to the complex nature of photons, it is ... -
Collective effects in biphoton generation of a four-wave-mixing process
(Universidade Federal de São Carlos, UFSCar, , Câmpus São Carlos, 28/04/2022)The generation of biphotons remains an important field of research, as several applications require such sources. For instance, some of their properties are fundamental in quantum communication, quantum computing, and ... -
