静态非极值AdS4黑洞解

Static nonextremal AdS4 black hole solutions

Chiara Toldo, Stefan Vandoren

摘要:

在D=4规范N=2的超引力中,我们发现了新的渐近于AdS_4的静态非极值黑洞解.解决方案包括具有恒定标量的电磁黑洞,它们在BPS极限下还原为裸奇点,但也包括具有运行标量的磁性黑洞,它们在极端情况下还原为具有有限视界面积的BPS黑洞。对于所有这些解决方案,我们计算面积积公式,并表明它们是独立的质量。最后,我们还发现了非极值磁黑膜的新例子。

英文摘要:

We find new static nonextremal black hole solutions that asymptote to AdS_4 in D=4 gauged N=2 supergravity. Solutions include electric and magnetic black holes with constant scalars that in the BPS limit reduce to naked singularities, but also magnetic black holes with running scalars that at extremality reduce to BPS black holes with finite horizon area. For all these solutions we compute area product formulae and show they are independent of the mass. Finally, we also find new examples of nonextremal magnetic black branes.
