再访Zitterbewegung
Revisiting Zitterbewegung
摘要:
电子的狄拉克波动方程很快导致了对Zitterbewegung的认识。薛定谔和狄拉克都对此进行了研究。后来,不同的作者又提出了一些优雅的、有时是不同意见的见解。我们简要回顾其中的一些发展。然而,随着暗能量和非对易时空的出现,早期对Zitterbewegung的研究受到质疑。
英文摘要:
The Dirac wave equation for the electron soon lead to the recognition of the Zitterbewegung. This was studied both by Schrodinger and Dirac. Later there were further elegant and sometimes dissenting insights, from different authors. We briefly review some of these developments. However in more recent times with dark energy and noncommutative spacetime coming to centre stage, the earlier studies of Zitterbewegung become questionable.
