论文摘要
使用Tachyon Matter \ cite {das}成功构建了带有Ellis几何形状的虫洞。但是,对于这样的虫洞,可以获得红移函数必须是一个常数,并且如果在没有宇宙学恒定项的情况下获得溶液,则虫洞也会受到假想的tachyon电位和恒定场的困扰。因此,只有在存在$λ$项的情况下,才有可能出现物理上合理的虫洞解决方案。在本文中,我们试图用Tachyon物质构建一个虫洞,并与Ellis几何形状的三个$其他几何\ TextIt {不同的}一起构建一个虫洞,并查看是否可以成功构造它们,除了检查是否还可以通过这些怪异来克服Ellis蠕虫的限制。除其他外,我们获得了一个非常有趣的结果,对于所有这三种几何\ textit \ textit {不同的},$λ$术语不再是构造物理上可行的可遍历蠕虫和tachyon物质的重要组成部分,并且能够为“ \ textbf {dark sector}提供解释,以提供解释。
Wormholes with Ellis geometry have been successfully constructed using tachyon matter \cite{Das}. However, for such a wormhole, it is obtained that the redshift function is necessarily a constant, and also the wormhole is plagued with an imaginary tachyon potential and a constant field if the solutions are obtained in the absence of a cosmological constant term. So, a physically plausible wormhole solution is possible only in the presence of a $Λ$ term. In this paper, we try to construct a wormhole from tachyon matter with three $other$ geometries \textit{different} from the Ellis geometry and see whether it is possible to construct them successfully, besides checking whether the restrictions of the Ellis wormhole can be overcome with these geometries. Among others, we obtain one very interesting result that for all three of these geometries \textit{different} from the Ellis, the $Λ$ term is no longer an essential ingredient in constructing physically plausible traversable wormholes and the tachyon matter, capable of providing explanations for the "\textbf{dark sector}" of the universe,is itself sufficient for this purpose.
