A critique of recent semi-classical spin-half quantum plasma theories
... orbit theory”. Specifically, if the time rate of change of the fields is measured by the frequency ω and the spatial scales are represented by the wave number k , drift orbit theory may be used when ρ∗ = Max[kρe , ωωce ] ≪ 1. Here, c⊥ is the “peculiar velocity” of the electron’s Larmor gyro motion. ...
