匹配展开法&格林函数的奇异结构

Method of Matched Expansions & the Singularity Structure of the Green Function

Marc Casals, Sam Dolan, Adrian C. Ottewill, Barry Wardell

摘要:

本文首次成功地应用匹配展开法计算了弯曲时空中点粒子的自作用力。我们调查的情况下,标量收费的Nariai时空,作为一个玩具模型的质点在史瓦西黑洞背景下移动。我们讨论了格林函数超出正常邻域的奇异性结构和焦散线对零波传播的有趣影响。

英文摘要:

We present the first successful application of the method of Matched Expansions for the calculation of the self-force on a point particle in a curved spacetime. We investigate the case of a scalar charge in the Nariai spacetime, which serves as a toy model for a point mass moving in the Schwarzschild black hole background. We discuss the singularity structure of the Green function beyond the normal neighbourhood and the interesting effect of caustics on null wave propagation.
