The dynamics of the early universe in a model with radiation and a generalized Chaplygin gas
G. A. Monerat, C. G. M. Santos, G. Oliveira-Neto +2
The early universe is modeled through the quantization of a Friedmann-Robertson-Walker model with positive curvature of the spatial hypersurfaces. In this model, the universe is fi…
Quantum Cosmology with many fluids and the choice of cosmological time
G. A. Monerat, C. G. M. Santos, F. G. Alvarenga +4
In this work we propose the quantization of a cosmological model describing the primordial universe filled with five barotropic fluids, namely: radiation, dust, vacuum, cosmic stri…
Spin-polarized current, spin-transfer torque and spin Hall effect in presence of an electromagnetic non-minimal coupling
Rodrigo Turcati, Carlos Andres Bonilla Quintero, José Abdalla Helayël-Neto +1
In this contribution, we start off from a fully relativistic description of a single electron non-minimally coupled to an external electromagnetic field. Making direct use of the f…
Quantum cosmology of a Hořava-Lifshitz model coupled to radiation
G. Oliveira-Neto, L. G. Martins, G. A. Monerat +1
In the present paper, we canonically quantize an homogeneous and isotropic Hořava-Lifshitz cosmological model, with constant positive spatial sections and coupled to radiation. We…
A Spectral Approach for Solving the Nonclassical Transport Equation
R. Vasques, L. R. C. Moraes, R. C. Barros +1
This paper introduces a mathematical approach that allows one to numerically solve the nonclassical transport equation in a deterministic fashion using classical numerical procedur…
Vacuum solutions in the Einstein-Aether Theory
M. Campista, R. Chan, M. F. A. da Silva +3
The Einstein-Aether (EA) theory belongs to a class of modified gravity theories characterized by the introduction of a time-like unit vector field, called aether. In this scenario,…
