O problema Fermi-Pasta-Ulam-Tsingou: equipartição de energia vista através de simulações computacionais
(Universidade Federal de São Carlos, 2021-11-25)
The equipartition of energy is one of the most fundamental results of Statiscal Mechanics, appearing in a broad range of physical systems. In order to explore this concept, two computational experiments of the Fermi-Past ...
Fabricação de um circuito lock-in para a estabilização de frequência de diodo
(Universidade Federal de São Carlos, 2021-06-30)
A cold atom experiment requires lasers with stable frequencies. In this work, we fabricated and characterized a lock-in circuit for frequency stabilization of a laser diode. The principle of stabilizing a physical quantity ...
Simulações de Monte Carlo para estudar a propagação da luz através da pele de diferentes fototipos
(Universidade Federal de São Carlos, 2021-11-26)
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 ...
Características luminescentes do sistema relaxor PLMN-13PT dopado com érbio em transições de fase polar
(Universidade Federal de São Carlos, 2021-11-25)
Structural and polar phase transitions are important for materials studies, specially for normal and relaxor ferroelectrics. These states influence the materials physical characteristics, which are observable by many ...
