Abstract
Zitterbewegung (ZBW), the relativistic trembling motion predicted by the Dirac equation, has eluded direct experimental observation in free electrons because its characteristic length scale is the Compton wavelength $\lambda_C = h/mc \approx 2.4 \times 10^{-12}$ m, far below current detection thresholds. Guo, Xu & Gu (2025, arXiv:2511.21142) recently demonstrated that relativistic vortex electron wave packets carrying orbital angular momentum can amplify the ZBW amplitude substantially beyond th
