论文摘要
在量子宇宙学中，必须选择所考虑的量子状态方程的特定波函数解决方案，以获得具体的结果。在不同的框架中，在许多情况下，已经探索了最简单的选择。由于量子宇宙学中没有共识的边界条件建议，因此我们研究了在沿de broglie-bohm量子理论的线路上解释的Wheeler-Dewitt方程的特定框架中扩大宇宙初始波函数的已知初始波函数集的后果。特别是，我们表明获得了许多不对称的量子弹跳，在量子背景本身中，这可能包含非平凡的反反应机制，作为弹跳周围量子粒子的产生。特别是，在基本量子平坦时空的量子波动中可能出现了我们扩展的宇宙的旧假设，在不同但未开发的视角内。
In quantum cosmology, one has to select a specific wave function solution of the quantum state equations under consideration in order to obtain concrete results. The simplest choices have been already explored, in different frameworks, yielding, in many cases, quantum bounces. As there is no consensually established boundary condition proposal in quantum cosmology, we investigate the consequences of enlarging known sets of initial wave functions of the universe, in the specific framework of the Wheeler-DeWitt equation interpreted along the lines of the de Broglie-Bohm quantum theory, on the possible quantum bounce solutions which emerge from them. In particular, we show that many asymmetric quantum bounces are obtained, which may incorporate non-trivial back-reaction mechanisms, as quantum particle production around the bounce, in the quantum background itself. In particular, the old hypothesis that our expanding universe might have arisen from quantum fluctuations of a fundamental quantum flat space-time is recovered, within a different and yet unexplored perspective.
