In this article, the possibility of construction of a traversable wormhole on the Randall–Sundrum braneworld with non-exotic matter employing the Kuchowicz potential has been studied. We have obtained the solution for the shape function of the wormhole and studied its properties along with validity of null energy condition. The junction conditions at the surface of the wormhole are used to evaluate the model parameters. We also evaluate the surface density and surface pressure for the wormhole. We study the geometrical nature of the wormhole and consider the radial and tangential tidal constraints on a traveller trying to traverse the wormhole. Besides, a linearized stability analysis is performed to obtain the region of stability for the wormhole. Our analysis, besides giving an estimate for the bulk equation of state (EoS) parameter, imposes restrictions on the brane tension, which is a very essential parameter in braneworld physics, and very interestingly the restrictions imposed by our physically plausible and traversable wormhole model are in conformity with those imposed by other braneworld geometries which are not associated with a wormhole solution. Besides, it is important to study such constraints imposed by geometrical objects such as wormholes on any gravity theory operating at high-energy scales like braneworld, as wormholes are believed to have been formed from massive compact objects of high energy densities. Also, we go on to justify that the possible detection of a wormhole may well indicate that we live on a three-brane universe.

具有非奇异物质的膜上可穿越虫洞:更广阔的视野

在这篇文章中,研究了利用 Kuchowicz 势在 Randall-Sundrum 膜世界上用非奇异物质构建可穿越虫洞的可能性。我们已经获得了虫洞形状函数的解,并研究了它的性质以及零能量条件的有效性。虫洞表面的连接条件用于评估模型参数。我们还评估了虫洞的表面密度和表面压力。我们研究了虫洞的几何性质,并考虑了对试图穿越虫洞的旅行者的径向和切向潮汐约束。此外,进行了线性化稳定性分析以获得虫洞的稳定区域。我们的分析除了给出体状态方程 (EoS) 参数的估计值外,对膜张力施加限制,这是膜世界物理学中非常重要的参数,非常有趣的是,我们物理上合理且可穿越的虫洞模型施加的限制与其他与虫洞解决方案无关的膜世界几何形状施加的限制一致。此外,重要的是研究虫洞等几何物体对任何在高能尺度(如膜世界)运行的引力理论施加的限制,因为虫洞被认为是由高能量密度的大质量致密物体形成的。此外,我们继续证明可能检测到虫洞很可能表明我们生活在一个三膜宇宙中。非常有趣的是,我们物理上合理且可穿越的虫洞模型所施加的限制与其他与虫洞解决方案无关的膜世界几何形状所施加的限制是一致的。此外,重要的是研究虫洞等几何物体对任何在高能尺度(如膜世界)运行的引力理论施加的限制,因为虫洞被认为是由高能量密度的大质量致密物体形成的。此外,我们继续证明可能检测到虫洞很可能表明我们生活在一个三膜宇宙中。非常有趣的是,我们物理上合理且可穿越的虫洞模型所施加的限制与其他与虫洞解决方案无关的膜世界几何形状所施加的限制是一致的。此外,重要的是研究虫洞等几何物体对任何在高能尺度(如膜世界)运行的引力理论施加的限制,因为虫洞被认为是由高能量密度的大质量致密物体形成的。此外,我们继续证明可能检测到虫洞很可能表明我们生活在一个三膜宇宙中。重要的是研究虫洞等几何物体对任何在高能尺度(如膜世界)运行的引力理论施加的限制,因为虫洞被认为是由高能量密度的大质量致密物体形成的。此外,我们继续证明可能检测到虫洞很可能表明我们生活在一个三膜宇宙中。重要的是研究虫洞等几何物体对任何在高能尺度(如膜世界)运行的引力理论施加的限制,因为虫洞被认为是由高能量密度的大质量致密物体形成的。此外,我们继续证明可能检测到虫洞很可能表明我们生活在一个三膜宇宙中。
