具有超标度破坏和Nil几何视界的真空Einstein方程的新黑洞

New black holes of vacuum Einstein equations with hyperscaling violation and Nil geometry horizons

Mokhtar Hassaine

摘要:

本文给出了一个新的五维真空Einstein方程的解,该方程是一个具有超标度破坏的静态黑洞,其三维视界是由Thurston几何之一,即Nil几何模拟的.这种齐次几何是非平凡的,因为它既不是常曲率的,也不是常曲率流形的乘积。利用哈密顿形式,我们确定了黑洞解的质量和熵。奇怪的是,尽管熵变为负值,质量却为正值,热力学热力学第一定律成立。我们还讨论了在高维空间中的扩张。

英文摘要:

In this paper, we present a new solution of the vacuum Einstein equations in five dimensions which is a static black hole with hyperscaling violation and with a three-dimensional horizon modeled by one the eight Thurston geometries, namely the Nil geometry. This homogeneous geometry is non-trivial in the sense that it is neither of constant curvature nor a product of constant curvature manifolds. Using the Hamiltonian formalism, we identify the mass and entropy of the black hole solution. Curiously enough, in spite of the fact that the entropy turns to be negative, the mass is positive and the first law of thermodynamics holds. We also discuss the extension in higher dimension.
