奇维时空中的自作用力和同步辐射
Self-force and synchrotron radiation in odd space-time dimensions
摘要：
平坦3+1时空中的经典电动力学有一个非常特殊的滞后传播子δ（x^2），它定域在光锥上，因此粒子不会与它过去的场发生相互作用。然而，这是一个例外，在平坦的奇维时空以及一般的弯曲空间中，情况并非如此。在这项工作中，我们表明，所谓的自作用力不仅是非零的，但它匹配（在2+1维）的辐射反作用力来自辐射强度。
英文摘要：
Classical electrodynamics in flat 3+1 space-time has a very special retarded propagator delta(x^2) localized on the light cone, so that a particle does not interact with its past field. However, this is an exception, and in flat odd-dimensional space-times as well as generic curved spaces this is not so. In this work we show that the so called self-force is not only non-zero, but it matches (in 2+1 dimensions) the radiation reaction force derived from the radiation intensity.
