论文摘要
在本文中，我们研究了Newman-Penrose（NP）形式主义中的四维爱因斯坦 - 马克斯韦 - 迪拉顿（EMD）理论。我们将运动方程式调整为NP形式主义，并获得渐近时空渐近的溶液空间。然后，我们研究重力和电磁记忆效应。我们发现DILATON不会导致位移或踢记忆效应，但确实有助于时间延迟的记忆效应。
In this paper, we study the four dimensional Einstein-Maxwell-dilaton (EMD) theories in the Newman-Penrose (NP) formalism. We adapt the equations of motion into the NP formalism, and obtain the solution space that is asymptotic to the flat space-time. We then investigate the gravitational and electromagnetic memory effects. We find that the dilaton does not contribute to the displacement nor the kick memory effects, but it does contribute to the time-delayed memory effect.
