弦云中的可穿越虫洞

Traversable wormholes in a string cloud

Martin Richarte, Claudio Simeone

摘要:

本文研究了(3+1)维时空中弦云背景下的球对称薄壳虫孔。奇异物质的建设所需的量,在径向扰动下的可穿越性和稳定性,作为模型的参数的函数进行了分析。此外,在附录中,一个非微扰方法的动力学和一个可能的扩展分析相关的模型进行了简要的讨论。

英文摘要:

We study spherically symmetric thin-shell wormholes in a string cloud background in (3+1)-dimensional spacetime. The amount of exotic matter required for the construction, the traversability and the stability under radial perturbations, are analyzed as functions of the parameters of the model. Besides, in the Appendices a non perturbative approach to the dynamics and a possible extension of the analysis to a related model are briefly discussed.
