超越广义相对论的薄壳虫孔微扰动力学:一种替代方法

Perturbative dynamics of thin-shell wormholes beyond general relativity: an alternative approach

Emilio Rubín de Celis, Cecilia Tomasini, Claudio Simeone

摘要:

最近的研究有关薄壳的状态方程的近似和随之而来的微扰演化扩展到薄壳虫洞的理论超越广义相对论和超过四个时空维度。静态和缓慢演化壳的状态方程的相同形式的假设似乎是一个强有力的限制,排除了振荡演化的可能性。然后,新的结果有很大的不同,从以前的通常的线性化的方法。

英文摘要:

Recent studies relating the approximations for the equations of state for thin shells and their consequent perturbative evolution are extended to thin-shell wormholes in theories beyond general relativity and more than four spacetime dimensions. The assumption of equations of state of the same form for static and slowly evolving shells appears as a strong restriction excluding the possibility of oscillatory evolutions. Then the new results considerably differ from previous ones obtained within the usual linearized approach.
