Método de baixo custo para reutilização de máscaras N95 através de recarga eletrostática
(Universidade Federal de Santa Maria, 2023-07-28)
Due to the Covid-19 pandemic, a disease caused by the Sars-CoV-2 virus, the
use of personal protective masks has increased dramatically. The World Health
Organization (WHO) recommends the PFF2 model, equivalent to the ...
O áxion em condições extremas: matéria de quarks quente e magnetizada, meios densos e estrelas compactas
(Universidade Federal de Santa Maria, 2023-07-31)
We investigate the phase diagram of quantum chromodynamics by means of the Nambu-
Jona-Lasinio effective model, including the axion - a particle which emerges as a solution
of the strong charge-parity (CP) problem and ...
Termodinâmica e transições de fase existentes na matéria de quarks com desbalanceamento quiral
(Universidade Federal de Santa Maria, 2023-07-01)
In this dissertation, we have used effective models, such as the Nambu-Jona-Lasinio (NJL)
and the Polyakov–Nambu–Jona-Lasinio (PNJL) to describe and study the Quantum Chromodynamics (QCD) phase diagram with chiral imbalance. ...
Efeitos do momento magnético anômalo na matéria de quarks
(Universidade Federal de Santa Maria, 2023-07-28)
This work aims to investigate the effect of anomalous magnetic moment (AMM) of quarks in
the NJL and PNJL two-flavor models at finite temperature, chemical potential, and magnetic
field. To achieve this, we employed the ...
Simulação de canais quânticos usando preparação variacional de estados
(Universidade Federal de Santa Maria, 2023-10-13)
Quantum computers still suffer from errors that keep them in the category of Noisy
Intermediate-Scale Quantum (NISQ) computers. Among the various tools capable of
circumventing some of the problems of NISQ computers, ...
Comportamento eletrostático em interface líquido-sólido: estratégias para detecção de fluxo de líquidos
(Universidade Federal de Santa Maria, 2024-02-19)
Although known since ancient times, triboelectricity is a phenomenon whose fundamental
causes are not yet fully understood, especially in liquid-solid interfaces. Significant
efforts have initiated studies on electrostatic ...
Comportamento magnético e efeito magnetocalórico de nanoestruturas frustradas de Ising
(Universidade Federal de Santa Maria, 2024-02-20)
In this work, we investigate the magnetic and magnetocaloric properties of two frustrated
Ising clusters in the presence of a longitudinal magnetic field: the centered tetrakis hexahedron
structure and the hexagonal ...
