Vortex-Enhanced Zitterbewegung in Relativistic Electron Wave Packets
Zhongze Guo, Bei Xu, Qiang Gu
Zitterbewegung (ZBW), the trembling motion predicted by the Dirac equation, has long remained unobservable in free electrons due to its sub-Compton scale. We elaborately construct…

Spin-Orbit Structure and Helicity Anomaly in Relativistic Electron Vortex Beams
Zhongze Guo, Bei Xu, Qiang Gu
The relativistic electron vortex beam (REVB) has attracted increasing attention due to its nontrivial spin-orbit structure recently. As relativistic electrons are governed by the D…
