加速宇宙的量子理论

Quantum theory of an accelerating universe

P. F. Gonzalez-Diaz, S. Robles-Perez

摘要:

我们回顾了量子宇宙学的一些众所周知的特征,例如因子排序问题、波函数和密度矩阵,对于暗能量主导的宇宙,可以获得解析解。对于幻影宇宙的特殊情况,我们提出了一个量子系统,其中量子信息理论中通常的定域性(非定域性)概念必须得到扩展。在这种情况下,我们也处理一个量子描述的存在,一个非时间区域周围的大裂缝奇点明确占。

英文摘要:

We review some of the well-known features of quantum cosmology, such as the factor ordering problem, the wave function and the density matrix, for a dark energy dominated universe, where analytical solutions can be obtained. For the particular case of the phantom universe, we suggest a quantum system in which the usual notion of locality (non-locality) of quantum information theory have to be extended. In that case, we deal also with a quantum description where the existence of a non-chronal region around the big rip singularity is explicitly accounted for.
