小宇宙学常数对电磁记忆效应的影响

Effect of small cosmological constant on electromagnetic memory effect

Sayali Atul Bhatkar

摘要:

我们考虑一个通用的散射过程,发生在一个区域的大小R内的静态补丁的德西特时空,使R小于曲率长度尺度的背景。因此,曲率的影响可以微扰地研究。我们得到的渐近电磁场产生的散射过程中,包括领先的一级修正,由于deSitter背景的存在,并讨论其普遍的方面。最后计算了由此产生的对平坦时空速度记忆效应的一阶修正。

英文摘要:

We consider a generic scattering process that takes place in a region of size R inside the static patch of the de Sitter spacetime such that R is smaller than the curvature length scale of the background. The effect of curvature can thus be studied perturbatively. We obtain the asymptotic electromagnetic field generated by the scattering process including the leading order correction due to the presence of de Sitter background and discuss its universal aspects. We finally caculate the resultant first order corrections to the flat spacetime velocity memory effect.
