Schwarzschild黑洞精细切片上的(非绝热)弦产生

(Non-adiabatic) string creation on nice slices in Schwarzschild black holes

Andrea Puhm, Francisco Rojas, Tomonori Ugajin

摘要:

在黑洞信息悖论的讨论中,漂亮的切片发挥了关键作用,因为它们避开了强时空曲率的区域,却平滑地穿过了下落的物质和向外的霍金辐射,从而证明了低能场论的使用是合理的。然而,为了避免信息丢失,最近有人提出,局域有效场论必须在视界处失效。为了评估这种崩溃的程度在紫外线完整的框架,我们研究弦理论对史瓦西黑洞的好片的影响。我们的目的是双重的。首先,我们使用漂亮的切片来解决arXiv:1402.1486中的各种未决问题和警告,其中有人认为,在视界处的增强非绝热弦理论效应可以为防火墙提供动力学机制。其次,我们确定了史瓦西黑洞中尼斯切片的两种非绝热效应:视界附近开弦的对产生因高度激发弦态无限塔的存在而增强,以及晚期非绝热效应固有的尼斯切片。

英文摘要:

Nice slices have played a pivotal role in the discussion of the black hole information paradox as they avoid regions of strong spacetime curvature and yet smoothly cut through the infalling matter and the outgoing Hawking radiation, thus, justifying the use of low energy field theory. To avoid information loss it has been argued recently, however, that local effective field theory has to break down at the horizon. To assess the extent of this breakdown in a UV complete framework we study string-theoretic effects on nice slices in Schwarzschild black holes. Our purpose is two-fold. First, we use nice slices to address various open questions and caveats of arXiv:1402.1486 where it was argued that boost-enhanced non-adiabatic string-theoretic effects at the horizon could provide a dynamical mechanism for the firewall. Second, we identify two non-adiabatic effects on nice slices in Schwarzschild black holes: pair production of open strings near the horizon enhanced by the presence of the infinite tower of highly excited string states and a late-time non-adiabatic effect intrinsic to nice slices.
