AI 中文摘要
在所有引力解中，可穿越虫洞尤为引人入胜，但在广义相对论框架下，它们几乎总是需要奇异物质，这必然违反零能量条件。修正引力理论中物质-几何耦合的引入提供了一个可行的平台，使得虫洞在有效引力场的支持下保持开放。因此，我们利用$f(R,T)$框架研究了慢速旋转可穿越虫洞的结构与性质。我们构建了与各向异性流体耦合的稳态虫洞模型，并证明它们是正则的、无视界的，在远距离处趋近于平坦时空几何，并在喉部满足外扩条件。我们的结果表明，所需物质同时满足零能量条件和强能量条件，证明旋转虫洞不一定需要非常规物质源。我们进一步研究了粒子轨迹、参考系拖拽现象以及由物质-几何耦合导致的非测地线行为，同时探讨了由旋转引起的弱场效应和透镜效应。我们的结果确立了$f(R,T)$引力中旋转虫洞潜在的天体物理可行性。
英文摘要
Among all gravitational solutions, traversable wormholes stand out as truly fascinating, yet within general relativity, they almost always demand exotic matter that necessarily violate null energy requirement. The inclusion of matter-geometry coupling in modified gravity theories provides a viable platform where wormholes remain open which are supported by effective gravitational field. We therefore examine the structure and properties of slowly rotating traversable wormholes using the $f(R,T)$ framework. We formulate stationary wormhole models coupled with the anisotropic fluid and show that they are regular, horizon-free, approach a flat spacetime geometry at large distances, and satisfy the flare-out requirement at the throat. Our results indicate that the required matter meets both the null and strong energy conditions, demonstrating that rotating wormholes do not necessarily require unconventional sources. We further study particle trajectories, frame dragging phenomena, and non-geodesic behavior resulting from matter-geometry coupling, alongside the weak-field and lensing effects caused by the rotation. Our results establish the potential astrophysical viability of rotating wormholes in $f(R,T)$ gravity.
