量子引力中的引力坍缩

Gravitational collapse in quantum gravity

Viqar Husain

摘要:

本文综述了近年来在量子引力中引力坍缩动力学的研究进展。它的目标是提供一个非微扰的计算框架来理解半经典近似和霍金辐射的出现。所研究的模型是球对称的引力-标量场理论。这个理论的量子化给出了相应的零膨胀和曲率算子的定义。与汉密尔顿算子一起,这些算子允许人们在无奇异性和么正性的环境中跟踪初始物质几何状态到捕获配置及更远的演化。

英文摘要:

We give a review of recent work aimed at understanding the dynamics of gravitational collapse in quantum gravity. Its goal is to provide a non-perturbative computational framework for understanding the emergence of the semi-classical approximation and Hawking radiation. The model studied is the gravity-scalar field theory in spherical symmetry. A quantization of this theory is given in which operators corresponding to null expansions and curvature are well defined. Together with the Hamiltonian, these operators allow one to follow the evolution of an initial matter-geometry state to a trapped configuration and beyond, in a singularity free and unitary setting.
