Motion driven by the exactly periodic field. Upper panel: Bz = 1.73T, Δz = ΔEg/2 and Tz (Bz) = 90 ps; lower panel: Bz = 6.92T, Δz = 2ΔEg, and Tz(Bz) = 22 ps. The states for ξn(t) are marked near the plots. The upper panel demonstrates a relatively slow dynamics on the top of the fast oscillations. The increase in the ξ2(t) term corresponds to the possible spin-flip due to the external electric field.
