论文摘要
我们介绍了检查称为量子尖峰的量子结构的结果。在重力系统中已知的经典尖峰发生在不均匀的空间的演变中。在Belinski-Halatnikov-Lifshitz场景的统一区域的动态中，可以看到不同种类的尖峰，我们称其为奇怪的尖峰。如果使用所谓的不均匀初始数据，则可以使它们可见。要探讨的问题是奇怪的尖峰是否可以在量化中幸存下来。答案是肯定的。但是，这是一种微妙的效果，需要使用复杂的分析和数值工具进行进一步检查。在古典和量子水平上，尖峰似乎至关重要，因为它们可以用作宇宙中真实结构的种子。
We present the result of our examination of quantum structures called quantum spikes. The classical spikes, that are known in gravitational systems, occur in the evolution of the inhomogeneous spacetimes. Different kind of spikes, which we name strange spikes, can be seen in the dynamics of the homogeneous sector of the Belinski-Khalatnikov-Lifshitz scenario. They can be made visible if the so-called inhomogeneous initial data are used. The question to be explored is whether the strange spikes may survive quantization. The answer is in the affirmative. However, this is rather a subtle effect that needs further examination using sophisticated analytical and numerical tools. The spikes seem to be of fundamental importance, both at classical and quantum levels, as they may serve as seeds of real structures in the universe.
