The Quantum State Of The Universe From Deformation Quantization and Classical-Quantum Correlation
M. Rashki, S. Jalalzadeh
In this paper we study the quantum cosmology of homogeneous and isotropic cosmology, via the Weyl-Wigner-Groenewold-Moyal formalism of phase space quantization, with perfect fluid…
On Quasinormal Modes for Scalar Perturbations of Static Spherically Symmetric Black Holes in Nash Embedding Framework
S. C. Ulhoa, R. G. G. Amorim, Abraão J. S. Capistrano
In this paper we investigate scalar perturbations of black holes embedded in a five dimensional bulk space. It is calculated the quasinormal frequencies of a such black holes using…
Effective perihelion advance and potentials in a conformastatic background with magnetic field
Abraão J. S. Capistrano, Antonio C. Gutiérrez-Piñeres
An Exact solution of the Einstein-Maxwell field equations for a conformastatic metric with magnetized sources is study. In this context, effective potential are studied in order to…
Non-singular Brans-Dicke collapse in deformed phase space
S. M. M. Rasouli, A. H. Ziaie, S. Jalalzadeh +1
We study the collapse process of a homogeneous perfect fluid (in FLRW background) with a barotropic equation of state in Brans-Dicke (BD) theory in the presence of phase space defo…
Anomalous precession of planets on a Weyl conformastatic solution
Abraão J. S. Capistrano, Joice A. M. Penagos, Manuel S. Alárcon
In this paper, we investigate the anomalous planets precession in the nearly-newtonian gravitational regime. This limit is obtained from the application of the slow motion conditio…
Test particles in a magnetized conformastatic spacetime
Antonio C. Gutiérrez-Piñeres, Abraão J. S. Capistrano, Hernando Quevedo
A class of exact conformastatic solutions of the Einstein-Maxwell field equations is presented in which the gravitational and electromagnetic potentials are completely determined b…
