论文摘要
了解时空和重力的量子性质仍然是理论物理学中最雄心勃勃的目标之一。它有望为基本粒子理论,天体物理学,宇宙学和物理基础提供关键的新见解。尽管有一个共同的目标,但量子重力研究人员社区有时被视为分为以不同的,相互排斥的方法的子社区。然而,在实践中,近年来表明了由不同的子社区产生的常见技术,结果和物理思想的出现,这表明了传统上不同方法之间的协作和互动的令人兴奋的新前景。在这份白皮书中,我们讨论了一些普遍的主题,这些主题已经从各个方向上越来越兴趣,并认为专注于它们将有助于整体上朝着共同的目标实现量子重力社区。
Understanding the quantum nature of spacetime and gravity remains one of the most ambitious goals of theoretical physics. It promises to provide key new insights into fundamental particle theory, astrophysics, cosmology and the foundations of physics. Despite this common goal, the community of quantum gravity researchers is sometimes seen as divided into sub-communities working on different, mutually exclusive approaches. In practice however, recent years have shown the emergence of common techniques, results and physical ideas arising from different sub-communities, suggesting exciting new prospects for collaboration and interaction between traditionally distinct approaches. In this White Paper we discuss some of the common themes which have seen a growing interest from various directions, and argue that focusing on them will help the quantum gravity community as a whole towards shared objectives.
