关于经典带电粒子的运动

On the motion of a classical charged particle

J. M. Aguirregabiria, J. Llosa, A. Molina

摘要:

证明了洛伦兹-狄拉克方程不是点电荷能量动量守恒的必然结果。仅仅从守恒定律出发,就可以得到一个限制性较小的方程,这个方程已经由霍尼格和萨莫西得到了。后者不是一个正确的运动方程,因为它包含一个额外的标量变量,它不决定电荷的未来演化。我们证明,可以添加一个补充的本构关系,使运动是确定的,并摆脱麻烦,是习惯的洛伦兹-狄拉克方程,即。e.预加速和失控

英文摘要:

We show that the Lorentz-Dirac equation is not an unavoidable consequence of energy-momentum conservation for a point charge. What follows solely from conservation laws is a less restrictive equation already obtained by Honig and Szamosi. The latter is not properly an equation of motion because, as it contains an extra scalar variable, it does not determine the future evolution of the charge. We show that a supplementary constitutive relation can be added so that the motion is determined and free from the troubles that are customary in Lorentz-Dirac equation, i. e. preacceleration and runaways.
