Quasilocal formalism and thermodynamics of asymptotically flat black objects

Dumitru Astefanesei, Robert B. Mann, Maria J. Rodriguez, Cristian Stelea

摘要:

利用局部渐近平坦时空的重整化边界应力张量研究了5维黑天体的性质。这提供了一个更精细的形式的准局部形式主义,这是有用的全息解释渐近平坦的引力。我们应用这种技术来研究黑洞,黑环和黑弦的热力学性质。使用这种方法的优点是,我们可以超越“薄环”近似和计算任何一般(薄或胖)黑环解决方案的边界应力张量。我们认为,边界应力张量编码的必要信息,以区分黑色物体与不同的地平线拓扑结构的散装。我们还详细研究了susy black环,阐明了渐近荷与视界上定义的荷之间的关系。此外,我们得到了“薄”偶极黑环的平衡条件。

英文摘要:

We study the properties of 5-dimensional black objects by using the renormalized boundary stress-tensor for locally asymptotically flat spacetimes. This provides a more refined form of the quasilocal formalism which is useful for a holographic interpretation of asymptotically flat gravity. We apply this technique to examine the thermodynamic properties of black holes, black rings, and black strings. The advantage of using this method is that we can go beyond the `thin ring' approximation and compute the boundary stress tensor for any general (thin or fat) black ring solution. We argue that the boundary stress tensor encodes the necessarily information to distinguish between black objects with different horizon topologies in the bulk. We also study in detail the susy black ring and clarify the relation between the asymptotic charges and the charges defined at the horizon. Furthermore, we obtain the balance condition for `thin' dipole black rings.
