作为非保守力的辐射反应

Radiation Reaction as a Non-conservative Force

Sandeep Aashish, Asrarul Haque

摘要:

利用Galley[1]最近提出的非保守系统的Hamilton原理,研究了有限尺寸带电粒子与辐射场相互作用系统。该公式导出了带电粒子的运动方程,其结果与Jackson[3]得到的相同。我们表明,辐射反应源于有效拉格朗日量的非保守部分。我们注意到,一个与辐射场相互作用的热浴模型提供了一种方法来证明辐射反应是一个非保守力。本课题适用于高等电动力学和经典场论的研究生课程。

英文摘要:

We study a system of a finite size charged particle interacting with radiation field by exploiting the Hamilton's principle for non-conservative system introduced recently by Galley[1]. The said formulation leads to the equation of motion of the charged particle that turns out to be the same as obtained by Jackson[3]. We show that radiation reaction stems from the non-conservative piece of the effective Lagrangian. We notice that a charge interacting with radiation field modeled as heat bath affords a way to justify that radiation reaction is a non-conservative force. The topic is suitable for graduate courses on advanced electrodynamics and classical theory of fields.
