量子约化圈引力:宇宙学

Quantum-Reduced Loop Gravity: Cosmology

Emanuele Alesci, Francesco Cianfrani

摘要:

我们引入了一个新的框架圈量子引力:模仿spinfoam量子化过程中,我们建议研究对称部门的理论施加的减少弱的完整的运动学希尔伯特空间的正则理论。作为量子约化圈引力的第一个应用,我们研究了非均匀Bianchi I模型。新兴的量子宇宙学模型代表了一个简化的竞技场,在这个竞技场上可以测试完整的正则量子化程序。这些分析的结果可以阐明圈量子宇宙学与完整理论的关系。

英文摘要:

We introduce a new framework for loop quantum gravity: mimicking the spinfoam quantization procedure we propose to study the symmetric sectors of the theory imposing the reduction weakly on the full kinematical Hilbert space of the canonical theory. As a first application of Quantum-Reduced Loop Gravity we study the inhomogeneous Bianchi I model. The emerging quantum cosmological model represents a simplified arena on which the complete canonical quantization program can be tested. The achievements of this analysis could elucidate the relationship between Loop Quantum Cosmology and the full theory.
