Black holes in the presence of dark energy

E. O. Babichev, V. I. Dokuchaev, Yu. N. Eroshenko

摘要:

综述了近年来迅速发展的新的理论研究领域-暗能量与黑洞相互作用(特别是在黑洞上的吸积)的研究。术语“暗能量”意在涵盖广泛的场论模型,以及具有各种状态方程的完美流体,包括宇宙学暗能量。各种吸积模型进行了分析,在最简单的测试场近似或允许反反应的黑洞度规。研究了史瓦西和带电黑洞附近各种暗能量的行为。讨论了由于黑洞附近存在暗能量而引起的非平凡效应。特别是,给出了物理解释为什么黑洞质量减少时,幻影能量被吸积,在这个过程中,著名的定理的基本能量条件的非减少视界面积在经典黑洞被违反。从理论上的可能性,从黑洞事件视界下逃逸的信号进行了讨论的暗能量模型的数量。最后,考虑了非正则场存在下黑洞对热力学定律的违反。

英文摘要:

The new, rapidly developing field of theoretical research --- studies of dark energy interacting with black holes (and, in particular, accreting onto black holes) --- is reviewed. The term `dark energy' is meant to cover a wide range of field theory models, as well as perfect fluids with various equations of state, including cosmological dark energy. Various accretion models are analyzed in terms of the simplest test field approximation or by allowing back reaction on the black-hole metric. The behavior of various types of dark energy in the vicinity of Schwarzschild and electrically charged black holes is examined. Nontrivial effects due to the presence of dark energy in the black hole vicinity are discussed. In particular, a physical explanation is given of why the black hole mass decreases when phantom energy is being accreted, a process in which the basic energy conditions of the famous theorem of nondecreasing horizon area in classical black holes are violated. The theoretical possibility of a signal escaping from beneath the black hole event horizon is discussed for a number of dark energy models. Finally, the violation of the laws of thermodynamics by black holes in the presence of noncanonical fields is considered.
