Symbol omega_Z

The passage around this formula

…equation of motion picks up, alongside the ordinary uniform drift, an oscillating term with no classical counterpart: an angular frequency $\omega_Z = \frac{2Mc^2}{\hbar}$. set purely by the rest mass. For an electron this is $\omega_Z$ $\approx$ 1.55$\times$10^{21}\ $\mathrm{rad\,s^{-1}}$ , an oscillation period of roughly four zeptoseconds in the particle’s own rest frame — a boosted lab observer would clock a longer, time-dilated period by the ordinary factor $\gamma$ , coordinate time and proper time parting ways in exactly…
