Average current spectra versus quantum dot energy at various amplitudes of the symmetrical time-dependent field. For clear indication of the spectra evolution, the range of the field amplitude W_L(R) covers (a) 0 to 1.5 and (b) 2 to 3 in the subfigures. The typical parameters are k = 2, ω = 1.0, Δ ϕ_R = 0, and ψ = 0.
