膜世界中的进化虫洞

Evolving wormhole in the brane-world scenario

Foad Parsaei, Nematollah Riazi

摘要:

本文研究了膜世界情形下的演化虫洞。我们研究了具有不同形式Ricci标量的可能的动力学解。本文研究了在不借助奇异物质的情况下,动态可穿越虫洞存在的可能性。利用膜修正使爱因斯坦场方程在3+1维中得到修正的事实,研究了满足零能量条件的精确解。渐近平坦性是这些解的一个重要性质。我们讨论了一些物理和数学性质的解决方案。

英文摘要:

In this paper, evolving wormholes in the context of brane-world scenario are investigated. We have studied the possible dynamic solutions with different forms of Ricci scalar. The possibility of existence of dynamic traversable wormholes, without resorting to an exotic matter, has been studied. By using the fact that the Einstein field equations are modified in 3+1 dimensions due to the brane corrections, we investigate the exact solutions which satisfy null energy condition. Asymptotic flatness is an important property of these solutions. We discuss some physical and mathematical properties of the solutions.
