全息时空和黑洞残余物作为暗物质

The holographic space-time and black hole remnants as dark matter

Aurélien Barrau

摘要:

暴胀的全息时空方法为研究早期宇宙提供了一个定义明确、自成一体的框架。它基于准定域量子引力理论,将弦论推广到AdS背景之外,解决了时间箭头和初始宇宙状态熵等基本问题。最近有人认为,它也为原始黑洞形式的暗物质提供了一个自然的解释。然而,最初的想法遭受麻烦,可以通过考虑普朗克遗物来解决。这种可能性进行了调查,并指出了观测确认的路径。

英文摘要:

The holographic space-time approach to inflation provides a well defined and self-contained framework to study the early universe. Based on a quasi-local quantum gravity theory generalizing string theory beyond AdS backgrounds, it addresses fundamental questions like the arrow of time and the entropy of the initial cosmological state. It was recently argued that it also provides a naturel explanation for dark matter in the form of primordial black holes. The orignal idea however suffers from troubles that can be cured by considering instead Planck relics. This possibility is investigated and paths for observational confirmation are pointed out.
