薄壳层瞬子隧穿:物-物还是无-物?
Thin-shell instanton tunneling: something-to-something or nothing-to-something?
摘要:
在文献中存在两种对瞬子的解释。第一种解释认为瞬子是初始超曲面和最终超曲面之间的分界线。科尔曼-德·卢西亚瞬子就是这样一个例子。第二种解释,由Brown和Weinberg提出,认为瞬子是初始和最终超曲面之间的连接子。在这一过程中,我们试图适当地和直观地认为,这两种解释是互补的,在某些条件下。此外,我们还证明了用欧几里得方法和哈密顿方法得到的衰变率是一致的,这可能有助于消除人们对正则化方法在瞬子尖点奇异性处理中的有效性的担忧.基于这些,我们认为,瞬子可以是一个明智的工具,以解决信息丢失的问题。
英文摘要:
There exist two interpretations of instantons in the literature. The first interpretation regards instanton as divider between the initial and final hypersurfaces. The Coleman-De Luccia instanton is one such an example. The second interpretation, proposed by Brown and Weinberg, considers instanton as connector between the initial and final hypersurfaces. In this proceedings, we try to suitably and intuitively argue that these two interpretations are complementary to each other under certain conditions. Furthermore, we demonstrate that the decay rate obtained from the Euclidean treatment and the Hamiltonian treatment both are consistent with each other, which may help to dissolve some concerns about the validity of regularization technique employed in the treatment of the cusp singularity of instantons. Based on these, we argue that instantons can be a sensible tool to address the information loss problem.
