摘要

在这项工作中,我们研究了修正 f(Q) 引力背景下的虫洞(WH)解的特性。形状函数(ξS(r))和红移函数(ζ(r))在虫洞建模中至关重要,因为它们决定了虫洞的度量并定义了虫洞的属性。这项研究提供了f(Q)引力特征与引力效应之间的相互作用,保证了对潜在虫洞配置的深入了解。随后,我们研究了能量条件的行为和虫洞的基本属性。此外,我们还研究了体积积分量子(V IQ),从而深入了解了虫洞咽喉附近所需的奇异物质数量。此外,还利用托尔曼-奥本海默-沃尔科夫(Tolman-Oppenheimer-Volkoff,TOV)方程检验了两种情况下虫洞解决方案的稳定性,结果表明两种虫洞解决方案都满足平衡要求。由于活动引力质量(Mactive)的上升特性,这两种情况都确保了 WH 解决方案在现实世界中的可接受性。我们的发现有助于当前关于替代引力理论和奇异时空几何的讨论。

Stability analysis of wormhole solutions in f(Q) gravity utilizing Karmarkar condition with radial dependent redshift function

In this work, we examine the properties of wormhole (WH) solutions in the context of modified f(Q) gravity. The shape function (ξS(r)) and redshift function (ζ(r)) are crucial in wormhole modeling since they determine the metric of a wormhole and define its attributes. The investigation provides the interaction between f(Q) gravity features and gravitational effects, guaranteeing insights into potential wormhole configurations. Subsequently, we have looked at the behavior of energy conditions and the fundamental properties of WHs. Additionally, the volume integral quantifier (V IQ) is addressed, providing insight into the quantity of exotic matter needed in the vicinity of the wormhole throat. Furthermore, the stability of the WH solutions in both cases is examined using the Tolman–Oppenheimer–Volkoff (TOV) equation where it is evident that both WH solutions meet the equilibrium requirements. Both cases ensures the real-world acceptability of WH solutions due to the rising nature of active gravitational mass (Mactive). Our findings contribute to the current discussion about alternative gravity theories and exotic spacetime geometries.
