Lorentz-Dirac方程和Dirac方程
The Lorentz-Dirac and Dirac Equations
摘要:
众所周知,电子的经典理论在$10^{-23} secs$量级的时间间隔,即康普顿时间,达到了它的描述极限。人们普遍认为,在这些时间间隔以下,经典电动力学不起作用,需要量子描述。利用Lorentz Dirac方程和电子的Dirac方程,我们指出,事实上,在康普顿尺度下,这两种描述是收敛的。
英文摘要:
It is well known that the Classical theory of the electron reached the limits of its description at time intervals of the order of $10^{-23} secs$, that is the Compton time. It is widely believed that below these time intervals Classical Electrodynamics doesn't work and that a Quantum description is required. Using the Lorentz Dirac and the Dirac equations of the electron, we point out that in fact there is a convergence of the two descriptions at the Compton scale.
