强引力场特有的动力学结构:量子形式

Dynamical structures specific to strong gravitational field: Quantum formalism

Andrzej Góźdź, Włodzimierz Piechocki, Grzegorz Plewa

摘要:

一般比安奇IX时空的动力学,在引力奇点附近,是贝林斯基、卡拉特尼科夫和利夫希茨方案的基础。渐近地,在奇点附近,方向标度因子(定义时空度规)的振荡被冻结,因此Bianchi IX模型的演化没有混沌特征。然而,它包括特殊的结构,我们称之为摆动,改变其性质的渐近制度。我们提出的形式主义,基于仿射量子化方案,在量子水平上检查的命运的摆动。我们提出了将经典摆动与量子摆动进行比较的方法。我们希望我们的工作可能有助于理解BKL场景的一些量子方面。

英文摘要:

The dynamics of the general Bianchi IX spacetime, near the gravitational singularity, underlies the Belinskii, Khalatnikov and Lifshitz scenario. Asymptotically, near the singularity, the oscillations of the directional scale factors (defining the spacetime metric) are freezed so the evolution of the Bianchi IX model is devoid of chaotic features. However, it includes special structures, that we call the wiggles, which change their properties in the asymptotic regime. We propose the formalism, based on an affine quantization scheme, to examine the fate of the wiggles at the quantum level. We present the way of comparing the classical wiggles with their quantum counterparts. We expect that our work may contribute towards understanding some quantum aspects of the BKL scenario.
