论文摘要
本文比较了单一黑洞S-Matrix的不同模型的特征,挑战和拼图,重点是最近的非标准模型以及“非暴力单位化”,该模型基于黑洞的新量子相互作用。作为比较的基础,首先概述了对实时霍金演化的描述,包括引力敷料和反射的领先效果。然后将连接与Qubit模型进行进化,并概述了一些技术以促进其描述。在量子模型中研究了非标准模型和非暴力单位化的重要特征,这说明了各自方法之间的基本差异。非标准模型提出了难题,以理解内部发出激发的演变,这可以通过诸如粒子衰减之类的相互作用而激发。进一步开发了用于非暴力单位化的量子模型,并很好地说明了该方法的各个方面。讨论了一些剩下的问题,以推广到更完整的进化模型。
This paper compares features, challenges, and puzzles of different models for a unitary black hole S-matrix, focussing on both recent nonisometric models, as well as "nonviolent unitarization," which is based on new quantum interactions of a black hole. As a foundation for comparison, the description of real-time Hawking evolution is first overviewed, including leading effects of gravitational dressing and backreaction. Connection is then made to qubit models for evolution, and some technology is outlined to facilitate their description. Important features of both nonisometric models and nonviolent unitarization are investigated in qubit models, which illustrate essential differences between the respective approaches. The nonisometric models present puzzles for understanding evolution of internal outgoing excitations, which can be excited by interactions such as particle decay. Qubit models for nonviolent unitarization are further developed, and nicely illustrate aspects of that approach. Some remaining questions in generalizing to more complete models for evolution are discussed.
