基于广义引力理论的曲率虫洞解重构

Reconstructing wormhole solutions in curvature based Extended Theories of Gravity

Vittorio De Falco, Emmanuele Battista, Salvatore Capozziello, Mariafelicia De Laurentis

摘要:

静态和球对称的虫洞解可以在基于曲率的广义引力理论的框架下重建。特别是,广义相对论在度量和曲率形式主义中的扩展产生了修正的引力势,由经典的牛顿势和Yukawa修正构成,其参数可以反过来通过观测来测量。这样的方法允许重建时空的虫洞喉考虑渐近平坦性作为相关的引力场的物理性质。这样的论点可以适用于一大类曲率理论表征虫洞通过参数的潜力。根据这个过程,可能的虫洞解决方案可以观测约束。另一方面,稳定的和可穿越的虫洞可能是这类广义引力理论的直接探测器。

英文摘要:

Static and spherically symmetric wormhole solutions can be reconstructed in the framework of curvature based Extended Theories of Gravity. In particular, extensions of the General Relativity, in metric and curvature formalism give rise to modified gravitational potentials, constituted by the classical Newtonian potential and Yukawa-like corrections, whose parameters can be, in turn, gauged by the observations. Such an approach allows to reconstruct the spacetime out of the wormhole throat considering the asymptotic flatness as a physical property for the related gravitational field. Such an argument can be applied for a large class of curvature theories characterising the wormholes through the parameters of the potentials. According to this procedure, possible wormhole solutions could be observationally constrained. On the other hand, stable and traversable wormholes could be a direct probe for this class of Extended Theories of Gravity.
