Evolving wormhole formation in dRGT massive gravity

Ayanendu Dutta, Dhritimalya Roy, Subenoy Chakraborty

AI总结:

本文在 dRGT 大质量引力中研究了含无迹、正压和各向异性压力流体的演化虫洞解,发现喉部加速膨胀,并证明喉部可在非奇异物质条件下存在多种演化构型。

摘要:

在本研究中,我们在爱因斯坦大质量引力框架内考察了演化虫洞解,考虑了无迹、正压和各向异性压力流体。我们对由虫洞解导出的常数所施加的约束进行了全面分析。研究发现,位于两个渐近宇宙之间的虫洞喉部同时发生加速膨胀。对无迹、正压和各向异性流体的能量条件的详细研究表明,在喉部具有非奇异物质的演化虫洞构型存在广泛的可能性。我们还考察了这一特征对本研究中出现的各种参数的依赖性。

英文摘要:

In this study, we have examined the evolving wormhole solution within Einstein-massive gravity, considering traceless, barotropic, and anisotropic pressure fluids. We have conducted a comprehensive analysis of the constraints imposed by the constants derived from the wormhole solution. It is found that the wormhole throat, situated between two asymptotic universes, undergoes simultaneous expansion with acceleration. A detailed investigation of the energy conditions for traceless, barotropic, and anisotropic fluids suggests a wide range of possibilities for evolving wormhole configurations with non-exotic matter at the throat. The dependency of this feature on the various parameters arising from the study has also been examined.
