论文摘要
在本文中，我们通过使用Wheeler-Dewitt方程（WDWE）与De Broglie-Bohm量子轨迹方法一起研究了增长宇宙的量子效应的变化。从WDWE，我们获得了量子修改的Friedmann方程，该方程与标准Friedmann方程相比具有其他称为量子潜力的术语。量子电位控制着早期宇宙的行为，为通货膨胀提供能量，而随着宇宙的增长，量子的能量迅速减少。成年宇宙的量子潜力远小于加速膨胀所需的量子潜力。这表明我们宇宙的量子效应不能被视为黑暗能量的候选者。
In this paper, we study the changes of quantum effects of a growing universe by using Wheeler-DeWitt equation (WDWE) together with de Broglie-Bohm quantum trajectory approach. From WDWE, we obtain the quantum modified Friedmann equations which have additional terms called quantum potential compared to standard Friedmann equations. The quantum potential governs the behavior of the early universe, providing energy for inflation, while it decreases rapidly as the universe grows. The quantum potential of the grown-up universe is much smaller than that required for accelerating expansion. This indicates that quantum effects of our universe cannot be treated as a candidate for dark energy.
