Chaubergin气体Hokava-Lifshitz量子宇宙学

Chaplygin Gas Hořava-Lifshitz Quantum Cosmology

Hossein Ardehali, Pouria Pedram

摘要:

本文研究了Chaubergin气体的Hoenava-Lifshitz量子宇宙学。利用Schutz形式和Arnowitt-Deser-Misner分解,得到了相应的Schrödinger-Wheeler-DeWitt方程.我们得到了精确的经典和量子力学解,并构造了波包来研究两种情况下标度因子期望值的时间演化。我们表明,不同于经典的解决方案,并选择适当的初始条件下,比例因子的期望值永远不会倾向于奇异点,表现出奇异性的自由行为的解决方案在量子域。

英文摘要:

In this paper, we study the Chaplygin gas Hořava-Lifshitz quantum cosmology. Using Schutz formalism and Arnowitt-Deser-Misner decomposition, we obtain the corresponding Schrödinger-Wheeler-DeWitt equation. We obtain exact classical and quantum mechanical solutions and construct wave packets to study the time evolution of the expectation value of the scale factor for two cases. We show that unlike classical solutions and upon choosing appropriate initial conditions, the expectation value of the scale factor never tends to the singular point which exhibits the singularity-free behavior of the solutions in the quantum domain.
