摘要
本文的重点是评估在f(R,T)重力下具有navarro - frank - white剖面的可穿越虫洞的可行性。我们的分析考虑了Morris-Thorne时空,建立了虫洞模型,并建立了相应于标准修正模型的各向异性运动方程。然后,我们通过考虑常数和可变红移函数来推导形状函数。这两个函数都满足了必要的条件,并在两个渐近平坦的时空区域之间建立了联系。然后,我们利用所建立的形状函数得到了几个解,并保证它们符合零能界的违反。此外,我们分析了复杂性因子和有效引力质量,并探索了流形上复杂性因子消失的点/区域。还证明了后一种量在某些时空区域中为负值。各种稳定性检查的含义也通过图形解释执行。结果表明,所构建的虫洞结构满足这些关键条件,从而保证了虫洞结构在扩展引力理论中的存在性。
Implications of vanishing complexity and Navarro-Frenk-White profile on the existence of traversable wormholes in f(R,T) gravity
This article focuses on assessing the viability of traversable wormholes admitting the Navarro-Frenk-White profile in gravity. Our analysis takes into account the Morris-Thorne spacetime to establish the wormhole model and constructs anisotropic equations of motion corresponding to a standard modified model. We are then engaged in deriving the shape functions by considering constant as well as variable redshift functions. Both these functions fulfill the required conditions and establish a link between two asymptotically flat areas of spacetime. Afterwards, we obtain a couple of solutions with the help of developed shape functions and ensure that they conform to the violation of null energy bounds. Additionally, we analyze the complexity factor as well as the active gravitational mass and explore the point/region on a manifold where the former factor vanishes. It is also demonstrated that the later quantity gains negative values in some spacetime regions. The implication of diverse stability checks is also performed through graphical interpretation. It is concluded that the constructed wormhole structures satisfy the key criteria, thereby their existence is ensured in this extended gravity theory.
