双曲黑洞与开弦产生

Hyperbolic Black Holes and Open String Production

Danjie Wenren

摘要:

本文研究了AdS $_5$中双曲黑洞附近的开弦偶产生效应。我们研究的经典动力学的D3探测膜在这个背景下,他们的量子隧穿率跨越视界从内部使用类似的方法,克劳斯,Parikh和Wilczek。双曲黑洞可以通过这些隧穿事件衰减,并估计了它们的寿命。辐射膜向边界移动,不会反弹回来。它们的世界线并不直接相交,也不碰撞奇点,这为研究在视界附近伸展在它们之间的开弦的非绝热对产生效应提供了一个干净的场景。我们发现,有一个定义良好的参数制度,可以有显着的对生产。这就要求辐射膜被高度提升。然而,这种膜的辐射在黑洞背景上仍然有很小的反作用,尽管它们上的开弦对产生可能会改变背景。我们评论我们的模型和AMPS悖论的可能关系。最后,讨论了目前存在的问题和今后的发展方向。

英文摘要:

In this paper we investigate open string pair production effects near hyperbolic black holes in AdS$_5$. We study the classical dynamics of D3 probe branes in this background and their quantum tunneling rate across the horizon from the inside using a method similar to that of Kraus, Parikh and Wilczek. The hyperbolic black holes can decay through these tunneling events and their lifetime is estimated. The radiated branes move towards the boundary and do not bounce back. Their world-lines do not intersect directly and they do not hit the singularity either, providing a clean scenario for studying the non-adiabatic pair production effects of open strings stretched between them near horizon. We find that there is a well defined parameter regime where there can be significant pair production. This requires the radiated branes to be highly boosted. However, the radiation of such branes still has small back-reaction on the black hole background, though the open string pair production on them can potentially alter the background. We comment on the possible relation of our model and the AMPS paradox. Some issues and future directions are discussed in the end.
