遗迹虫洞形成的可能情形

Possible scenario of relic wormhole formation

A. A. Kirillov, E. P. Savelova

AI总结:

该研究探讨早期宇宙中虚拟虫洞引发真空不稳定及相变,经Kibble情形产生带负能量密度的宏观缺陷,可支撑原初虫洞喉道,为遗迹虫洞作为现实天体物理对象提供依据。

摘要:

研究表明,在存在虚拟虫洞的情况下,真空是不稳定的,这会导致早期宇宙发生一系列相变。随后标准的Kibble情形预言会形成畴壁等缺陷。虚拟虫洞的一个不同寻常的特性是,它们会产生具有负能量密度的缺陷。这类缺陷具有宏观尺度,能够支撑已经真实存在的原初虫洞的喉道,这为将遗迹虫洞视为现实的天体物理对象提供了依据。

英文摘要:

It is shown that in the presence of virtual wormholes, the vacuum is unstable, which leads to a series of phase transitions in the early Universe. Then the standard Kibble scenario predicts the formation of defects such as domain walls. An unusual feature of virtual wormholes is that they generate defects with negative energy density. Such defects have macroscopic dimensions and can support the necks of already real primary wormholes, which gives reason to consider relic wormholes as realistic astrophysical objects.
