辐射反应与运动相对论荷电膜的电磁能量动量

Radiation Reaction and the Electromagnetic Energy-Momentum of Moving Relativistic Charged Membranes

A. O. Barut, M. Pavšič

摘要:

狄拉克的带电膜提供了一个稳定的电子模型,具有有限的自能量。它的总质量$m$先前已经从膜的哈密顿量计算。为了完成这幅图,我们在这里根据其自身场(辐射反应)的能量-动量对其进行评估,并获得相同的结果,表明模型的一致性。我们明确地表明,旧的4/3-问题不会出现。电子的稳定性(总${T^{μν}}_{, ν}$的消失)是由于膜的表面张力$κ$,但该模型与点粒子一样简单,具有两个参数$κ$和$e$ ;表面张力参数$κ$可以用质量$m$表示。

英文摘要:

The charged membrane of Dirac provides a stable electron model with finite self energy. Its total mass $m$ has been previously calculated from the Hamiltonian of the membrane. To complete the picture we evaluate it here on the basis of the energy-momentum of its self field (radiation reaction) and obtain the same result showing the consistency of the model. We show explicitly that the old 4/3-problem does not arise. The electron's stability (the vanishing of total ${T^{μν}}_{, ν}$) is due to surface tension $κ$ of the membrane, but the model is as simple as the point particle, with two parameters $κ$ and $e$; the surface tension parameter $κ$ can be expressed in terms of the mass $m$.
