孤立视界、p型物质场、拓扑学和黑洞/弦对应原理

Isolated horizons, p-form matter fields, topology and the black-hole/string correspondence principle

Tomas Liko

摘要:

研究了任意p型物质场存在下爱因斯坦引力的D维孤立视界的力学性质。这将科普塞和霍洛维茨的分析推广到了非定常时空,因此局域第一定律也包括了非单极(偶极)电荷。局部第一定律成立的唯一要求是作用必须是可微的。由此产生的守恒电荷都是视界固有的,并且与视界截面的拓扑结构无关。我们明确地计算了五维黑洞和黑环的局部电荷,这些都与超弦理论有关。最后,我们对黑洞/弦对应原理作了一些评论,并认为IHs(或其他准定域变体)应该在超弦理论中发挥基础性作用。

英文摘要:

We study the mechanics of D-dimensional isolated horizons (IHs) for Einstein gravity in the presence of arbitrary p-form matter fields. This generalizes the analysis of Copsey and Horowitz to non-stationary spacetimes and therefore the local first law to include non-monopolar (dipole) charges. The only requirement for the local first law to hold is that the action has to be differentiable. The resulting conserved charges are all intrinsic to the horizon and are independent of the topology of the horizon cross sections. We explicitly calculate the local charges for five-dimensional black holes and black rings that are relevant within the context of superstring theory. We conclude with some comments on the black-hole/string correspondence principle and argue that IHs (or some other quasilocal variant) should play a fundamental role in superstring theory.
