格圈量子引力

Lattice Loop Quantum Gravity

Johannes Aastrup, Jesper M. Grimstrup

摘要:

本文提出了一种基于立方格点归纳系统的可分离的圈量子引力(LQG)。我们构造半经典状态的LQG运营商-通量,面积和体积运营商-有正确的经典极限。此外,我们提出的Hamilton和同态约束作为算子的约束,并表明他们有正确的经典极限。最后,我们推测是否连续极限,这些半经典状态探测,可以定义为整个建设,从而恢复一个行动的反同态群。

英文摘要:

We present a separable version of Loop Quantum Gravity (LQG) based on an inductive system of cubic lattices. We construct semi-classical states for which the LQG operators -- the flux, the area and the volume operators -- have the right classical limits. Also, we present the Hamilton and diffeomorphism constraints as operator constraints and show that they have the right classical limit. Finally, we speculate whether the continuum limit, which these semi-classical states probe, can be defined for the entire construction and thereby restore an action of the diffeomorphism group.
