论文摘要
亚伯拉罕·洛伦兹 - 迪拉克理论预测了均匀加速电荷的消失辐射反应。但是，由于加速的观察者应检测到热辐射，因此应看到电荷在加速框架中吸收光子，如果没有其他事情会影响其运动。这意味着要么在惯性框架中看到辐射反应，要么在加速的框架中应该出现另一种现象，以抵抗吸收的作用。在本文中，我从量子电动力学中重新启动了亚伯拉罕 - 洛伦兹 - 迪拉克力，然后研究了均匀加速电荷的情况。我表明，在加速的框架中，除了由于未造成的效果而引起的光子外，还应刺激发射。这些现象对电荷运动的净影响为零。
The Abraham-Lorentz-Dirac theory predicts vanishing radiation reaction for uniformly accelerated charges. However, since an accelerating observer should detect thermal radiation, the charge should be seen absorbing photons in the accelerated frame which, if nothing else occurs, would influence its motion. This means that either there is radiation reaction seen in an inertial frame or there should be an additional phenomenon seen in the accelerated frame countering the effect of absorption. In this paper I rederive the Abraham--Lorentz--Dirac force from quantum electrodynamics, then I study the case of a uniformly accelerated charge. I show that in the accelerated frame, in addition to the absorption of photons due to the Unruh effect there should also be stimulated emission. The net effect of these phenomena on the motion of the charge is found to be zero.
