Efeitos da não-comutatividade do espaço-tempo sobre as propriedades termodinâmicas da corda negra

Abstract

Black holes are a subject of many works till the present day not only because they have interesting physics properties, but also because they seem to be the appropriate tool for studying gravity in quantum scale after the proposal of black hole radiation. A lot of effort was made with the intend of better understanding the aspects of spacetime in quantum scale and the approach which includes the noncommutativity reveals to be a promising one. In this work, we study the thermodynamical properties of cylindrical black holes (black strings) in noncommutative spacetime. Our aim is to provide understanding about the thermodynamics of these objects by considering the influence due noncommutativity since that scale of spacetime, in which the noncommutativity effects become more pronounced, is important for the comprehension of the relation between Quantum Mechanics and General Relativity.
