随机量子化的因果随机几何

Causal random geometry from stochastic quantization

J. Ambjorn, R. Loll, W. Westra, S. Zohren

摘要:

在这个简短的说明中,我们回顾了最近发现的二维因果量子引力通过因果动态三角剖分和随机量子化定义的公式。这一过程使人们能够提取的非微扰量子哈密顿量的随机表面模型,包括在拓扑结构的总和。有趣的是,通常虚构的随机时间对应于几何上的真时间。

英文摘要:

In this short note we review a recently found formulation of two-dimensional causal quantum gravity defined through Causal Dynamical Triangulations and stochastic quantization. This procedure enables one to extract the nonperturbative quantum Hamiltonian of the random surface model including the sum over topologies. Interestingly, the generally fictitious stochastic time corresponds to proper time on the geometries.
