Abstract

Since the general relativistic approach requires exotic matter with negative energy density, constructing wormholes containing realistic matter is a crucial challenge. Therefore, extending General Relativity to non-minimal cases may be an alternative option. In this paper, we investigate wormholes which are supported by the non-minimally coupled electromagnetic fields to gravity in Y(R)F2 form where F2 is the Maxwell invariant and Y(R) is a function of the Ricci scalar R. We consider both electrically and magnetically charged cases. Then we give some exact asymptotically AdS/dS and flat solutions for traversable wormhole geometries. By discussing whether these obtained geometries satisfy the energy conditions and vanishing sound speed condition, we determine stable solutions containing realistic matter for some parameter values.

电磁非微观耦合引力中的虫洞
由于广义相对论方法需要能量密度为负的奇异物质,因此构建包含现实物质的虫洞是一项重大挑战。因此,将广义相对论扩展到非最小情况可能是另一种选择。在本文中,我们研究了由非最小耦合电磁场和引力以 Y(R)F2 形式支持的虫洞,其中 F2 是麦克斯韦不变量,Y(R) 是利玛窦标量 R 的函数。然后,我们给出了可穿越虫洞几何的一些精确渐近 AdS/dS 和平面解。通过讨论这些得到的几何图形是否满足能量条件和声速消失条件,我们确定了在某些参数值下包含现实物质的稳定解。

期刊介绍: Nuclear Physics B focuses on the domain of high energy physics, quantum field theory, statistical systems, and mathematical physics, and includes four main sections: high energy physics - phenomenology, high energy physics - theory, high energy physics - experiment, and quantum field theory, statistical systems, and mathematical physics. The emphasis is on original research papers (Frontiers Articles or Full Length Articles), but Review Articles are also welcome.
