Title

Abstract

In this contribution, we will first make a brief survey of the area of black hole physics, analyzing the results of some theories and comparing with its description in the Poincaré theory. After this brief review we will treat new results from the description of the thermodynamics and spin current of a system corresponding to a new charged Black Hole surrounded by a quintessence potential and a global monopole in the context of the Poincaré gravity. In Poincaré's theory of gravity, in addition to mass-energy content, spin is also a source of gravitational interactions. Although the effects of spin are insignificant at low energies, they may be crucial in the primordial universe when spin density was very high. We find the solution corresponding to the space-time under consideration by taking into account that the action which describes this system besides gravity also contains quadratic terms of the curvature and torsion. The metric obtained is a function of mass, solid angle deficit and the coupling constants of the quadratic terms of the curvature and torsion. In this model, the stability of the system is studied through the analysis of the Hawking temperature and the specific heat. In this context it was also studied the critical temperatures of the system considering positive and negative values of the cosmological constant. In the vicinity of the black hole with a quintessence potential, where there is a logarithmic correction due to the relationship between the torsion and curvature, some analysis were done. We also study the AdS/dS limit where the black hole is analyzed from the topological point of view.
