电子结构,Zitterbewegung和新的非线性Dirac-like方程

Electron structure, Zitterbewegung, and the new non-linear Dirac-like equation

M. Pavsic, Erasmo Recami, W. A. Rodrigues

摘要:

最近的文献显示了对自旋经典理论的新的兴趣,有各种独立的方法。考虑到这些结果的可能的利益,至少对于电子的情况下,我们的目的是在本文中探索它们的物理和数学意义,通过自然和强大的语言Clifford代数(这,顺便说一句,将使我们能够统一这些不同的方法)。在这样的理论中,普通电子通常与点状“组分”Q的平均运动相关联,其轨迹是圆柱螺旋。我们发现,特别是,对象Q服从一个新的,非线性的狄拉克方程,这样-当平均超过一个内部循环(对应于线性化)-它转化为普通的狄拉克方程(有效的电子作为一个整体)。

英文摘要:

The recent literature shows a renewed interest, with various independent approaches, in the classical theories for spin. Considering the possible interest of those results, at least for the electron case, we purpose in this paper to explore their physical and mathematical meaning, by the natural and powerful language of Clifford algebras (which, incidentally, will allow us to unify those different approaches). In such theories, the ordinary electron is in general associated to the mean motion of a point-like "constituent" Q, whose trajectory is a cylindrical helix. We find, in particular, that the object Q obeys a new, non-linear Dirac-like equation, such that --when averaging over an internal cycle (which corresponds to linearization)-- it transforms into the ordinary Dirac equation (valid for the electron as a whole).
