中文摘要

量子引力的一个关键问题是理解一个正确的包含引力的高能理论,如弦论,如何在其低能极限下产生经典相对论。最近,经典热力学导出的黑洞熵与弦论中微正则系综导出的黑洞熵之间的联系得到了惊人的结果,这暗示了这些理论之间的深刻联系,但它的详细性质仍然让我们困惑。我们的四维时空的各向同性宇宙是如何从量子理论的初始状态中出现的,特别是一个可能在四维以上的空间中形成的理论?
英文摘要
A key issue in quantum gravity is to understand how a correct high energy theory that includes gravity, such as string theory, produces classical relativity in its low energy limit. Recent striking results relating black hole entropy derived by classical thermodynamics to that derived from a microcanonical ensemble in string theory hint at a deep connection between these theories, but its detailed nature still eludes us. How is it that our isotropic universe of 4 spacetime dimensions emerged from an initial state of a quantum theory, in particular, one likely formulated in more than 4 dimensions?
