AI 中文摘要
我们基于带电粒子同余的光学数据，发展了电磁记忆的几何表征。我们推导了无质量粒子和有质量粒子在零无穷远附近的世界线偏差，并构造了相应的光学数据。我们证明了带电粒子同余的渐近剪切提供了电磁记忆及其相关大规范变换的等效编码。这建立了电磁记忆和大规范变换在带电粒子同余渐近演化方面的几何解释。
英文摘要
We develop a geometric characterization of electromagnetic memory in terms of the optical data of charged-particle congruences. We derive the worldline deviation of charged particles near null infinity for both massless and massive particles and construct the corresponding optical data. We show that the asymptotic shear of the charged-particle congruence provides an equivalent encoding of electromagnetic memory and its associated large gauge transformation. This establishes a geometric interpretation of electromagnetic memory and large gauge transformations in terms of the asymptotic evolution of charged-particle congruences.
