论文摘要

低质量黑洞的批判形成是数值一般相对论的历史基石,对宇宙学对审查制度的猜想和原始黑洞(PBHS)的生产具有重要意义。近年来,与黑洞观察物理学的激增同时,人们对这些受试者的兴趣增加了。通常认为关键形成是PBH生产的一种机制,但是可能存在可能伴随更现实的情景的不同类型的关键过程的存在可能会影响到迄今为止所考虑的更大。本文数字研究了一个玩具模型,是球形对称标量场崩溃中多个近临界场的相互作用。据发现,〜I型和〜II型近临界场的组合导致了它们各自的批判发展和提出的一种竞争。对这种现象的一种启发式解释,采用了动态系统理论的思想。

The critical formation of low-mass black holes is a historical cornerstone of numerical General Relativity, with important implications in cosmology for censorship conjectures and the production of primordial black holes (PBHs). Concurrent with the surge in black hole observational physics in recent years has been an increased interest in these subjects. Critical formation is often suggested as a mechanism for PBH production, but it is possible that the existence of different types of critical processes potentially accompanying more realistic scenarios may affect this conclusion more than has been considered thus far. This paper numerically investigates, as a toy model, the interplay of multiple near-critical fields in the collapse of spherically symmetric scalar fields. It is found that a combination of type~I and type~II near-critical fields results in a kind of competition between their respective critical evolutions and propose. A heuristic explanation for this phenomenon is given employing ideas from the theory of dynamical systems.
