纯引力反作用观测量

Pure Gravitational Back-Reaction Observables

N. C. Tsamis, R. P. Woodard

摘要:

在讨论了各向同性条件下纯量子引力观测量的各种问题和要求后,我们构造了一个满足大部分要求的复合观测量。我们还扩大到一阶环计数参数,并建议它作为一个物理量词的引力反反应在最初的膨胀宇宙学。

英文摘要:

After discussing the various issues regarding and requirements on pure quantum gravitational observables in homogeneous-isotropic conditions, we construct a composite operator observable satisfying most of them. We also expand it to first order in the loop counting parameter and suggest it as a physical quantifier of gravitational back-reaction in an initially inflating cosmology.
