标量辐射和电磁辐射加速偶极子的辐射反应场

Radiation Reaction fields for an accelerated dipole for scalar and electromagnetic radiation

W. G. Unruh

摘要:

计算了标量场和电磁辐射场中加速变化偶极子的辐射反应场。加速度反应示出改变时变偶极子的阻尼在EM的情况下,但不是标量的情况下。在EM情况下,偶极辐射反应场可以对与加速偶极相关联的加速负电荷施加力。加速电荷的辐射反应不会对加速磁偶极子施加扭矩,但加速偶极子会对电荷施加力。所使用的技术是最初由彭罗斯开发的非奇异领域和作者扩展的一个加速电荷。

英文摘要:

The radiation reaction fields are calculated for an accelerated changing dipole in scalar and electromagnetic radiation fields. The acceleration reaction is shown to alter the damping of a time varying dipole in the EM case, but not the scalar case. In the EM case, the dipole radiation reaction field can exert a force on an accelerated monopole charge associated with the accelerated dipole. The radiation reaction of an accelerated charge does not exert a torque on an accelerated magnetic dipole, but an accelerated dipole does exert a force on the charge. The technique used is that originally developed by Penrose for non-singular fields and extended by the author for an accelerated monopole charge.
