标题： Classical and quantum radiation reaction for linear acceleration

摘要： 我们研究了辐射反作用对量子电动力学中线性加速的带电标量粒子波包运动的影响。 我们给出了粒子被静态势加速时计算细节，这些细节曾在《Phys. Rev. D》70 (2004) 081701(R) 中概述，并在时间依赖但空间独立的势的情况下呈现了类似的结果。 特别是，我们在 $\hbar \to 0$ 极限下以精细结构常数的一阶计算了加速后带电粒子位置的期望值，并发现由于辐射反作用导致的位置期望值变化（位置偏移）与经典电动力学中使用洛伦兹-狄拉克力得到的结果完全一致，适用于两种势。 我们还指出，势的一圈修正可能在这极限情况下对位置变化有贡献。 显示英文摘要

摘要： We investigate the effect of radiation reaction on the motion of a wave packet of a charged scalar particle linearly accelerated in quantum electrodynamics. We give the details of the calculations for the case where the particle is accelerated by a static potential that were outlined in Phys.Rev. D 70 (2004) 081701(R) and present similar results in the case of a time-dependent but space-independent potential. In particular, we calculate the expectation value of the position of the charged particle after the acceleration, to first order in the fine structure constant in the $\hbar \to 0$ limit, and find that the change in the expectation value of the position (the position shift) due to radiation reaction agrees exactly with the result obtained using the Lorentz-Dirac force in classical electrodynamics for both potentials. We also point out that the one-loop correction to the potential may contribute to the position change in this limit.
