极吸引子黑洞的流

Flows of Extremal Attractor Black Holes

Norihiro Iizuka, Akihiro Ishibashi, Kengo Maeda

摘要:

我们研究了非超对称吸引子黑洞在规范/引力对应下的流动。作为我们的体理论,我们考虑了Einstein-Maxwell-Dilaton系统,其中一个单介子场耦合到两个Maxwell场,并通过在单介子场中加入裸势来进行相应的变形。我们发现了两类具有吸引子机制的黑洞解:一类是视界光滑的,另一类是非光滑的。我们从体积和边界理论的角度表明,前者是不稳定的,而后者是稳定的。

英文摘要:

We study flows of non-supersymmetric attractor black holes in the context of gauge/gravity correspondence. As our bulk theory, we consider the Einstein-Maxwell-Dilaton system with a single dilaton field coupled to two Maxwell fields and make a relevant deformation by adding a bare potential to the dilaton field. We find two types of extremal black hole solutions with attractor mechanism: The one smooth at the horizon and the other non-smooth. We show from both bulk and boundary theory perspective that the former is thermodynamically unstable, while the latter is stable.
