Properties of nuclear pastas
(Frontiers Media, 2020-09)
In this review we study the nuclear pastas as they are expected to be formed in neutron star crusts. We start with a study of the pastas formed in nuclear matter (composed of protons and neutrons), we follow with the role ...
Phase transitions and symmetry energy in nuclear pasta
(Elsevier Science, 2018-07)
Cold and isospin-symmetric nuclear matter at sub-saturation densities is known to form the so-called pasta structures, which, in turn, are known to undergo peculiar phase transitions. Here we investigate if such pastas and ...
Beyond nuclear “pasta” : Phase transitions and neutrino opacity of new “pasta” phases
(American Physical Society, 2014-12)
In this work, we focus on different length scales within the dynamics of nucleons in conditions according to the neutron star crust, with a semiclassical molecular dynamics model, studying isospin symmetric matter at ...
Symmetry energy and the Pauli exclusion principle
(Multidisciplinary Digital Publishing Institute, 2021-11)
In this article we present a classical potential that respects the Pauli exclusion principle and can be used to describe nucleon-nucleon interactions at intermediate energies. The potential depends on the relative momentum ...
Effect of Coulomb screening length on nuclear "pasta" simulations
(American Physical Society, 2014-03)
We study the role of the effective Coulomb interaction strength and length on the dynamics of nucleons in conditions according to those in a neutron star's crust. Calculations were made with a semiclassical molecular ...
The nucleonic thermal conductivity of “pastas” in neutron star matter
(Elsevier Science, 2020-10)
This investigation explores the nucleonic thermal conductivity of nuclear star matter as it undergoes the “topological” transition to the “pasta” regime, and further down to the solid-liquid phase transition. The study was ...
Pasta nuclear e evolução de protoestrelas de nêutrons
(Florianópolis, 2013)
Exploración Analítica de Propiedades de Transporte de Materia Nuclear a Densidad Finita.
(Universidad de Concepción.Facultad de Ciencias Físicas y Matemáticas, 2023)
En esta tesis, describiremos los avances recientes en métodos analíticos para construir soluciones exactas del modelo Skyrme que representan condensados hadrónicos no homogéneos que viven en una densidad bariónica finita. ...
Topological characterization of neutron star crusts
(American Physical Society, 2012-11)
Neutron star crusts are studied using a classical molecular dynamics model developed for heavy-ion reactions. After the model is shown to produce a plethora of the so-called pasta shapes, a series of techniques borrowed ...
Estudo microestrutural de pastas de cimento modificadas por emulsões de base acrílica e acrílica-estirenada
(Universidade Federal de Pernambuco, 2014)
