常电磁场中平面运动Lorentz-Dirac方程物理解的渐近性

Asymptotics of physical solutions to the Lorentz-Dirac equation for a planar motion in constant electromagnetic fields

P. O. Kazinski, M. A. Shipulya

摘要:

本文研究了定常电磁场中Lorentz-Dirac方程的平面物理解。在这种情况下,我们将Lorentz-Dirac方程化为一个二阶微分方程。我们得到了该方程物理解的渐近性。结果表明,在具有消失不变量的交叉恒定均匀电磁场中,带电粒子在很大程度上进入普适状态。我们发现的动量分量的比例往往是一个常数,仅由外部场。这种效应主要是由于辐射反应。在这个领域中的洛伦兹方程没有这样的影响。

英文摘要:

We present a study of planar physical solutions to the Lorentz-Dirac equation in a constant electromagnetic field. In this case, we reduced the Lorentz-Dirac equation to the one second order differential equation. We obtained the asymptotics of physical solutions to this equation at large proper times. It turns out that, in the crossed constant uniform electromagnetic field with vanishing invariants, a charged particle goes to a universal regime at large times. We found the ratio of momentum components which tends to a constant determined only by the external field. This effect is essentially due to a radiation reaction. There is not such an effect for the Lorentz equation in this field.
