论文摘要
在这项工作中,我们将混合循环量子宇宙学的形式主义扩展到围绕平坦,同质和各向同性宇宙周围的原始扰动,以根据替代对哈米尔顿(Hamiltonian)的替代性正常化的约束,对Friedmann-Lema-Robertson-Walker Geometries的新处理。实际上,我们的讨论也适用于其他可能的正规化方案,用于循环量子宇宙学,尽管我们将分析专门针对Dapor-Liegener提案,并且明确构建了所有涉及该情况的量子操作员。
In this work, we extend the formalism of hybrid loop quantum cosmology for primordial perturbations around a flat, homogeneous, and isotropic universe to the new treatment of Friedmann-Lemaître-Robertson-Walker geometries proposed recently by Dapor and Liegener, based on an alternative regularization of the Hamiltonian constraint. In fact, our discussion is applicable also to other possible regularization schemes for loop quantum cosmology, although we specialize our analysis to the Dapor-Liegener proposal and construct explicitly all involved quantum operators for that case.
