Representation for the frequency numbers in Rabi oscillations between the ground state and (a) the singly-excited Rydberg state, (b) the doubly-excited Rydberg state, versus Ω_eff and U_dd, with Ω_eff/Ω₁ ϵ [−5,5], U_dd/Ω₁ϵ[−10,10], and Ω₁ = 20 MHz. The parametric regions for Figs. 3(a) and 3(b) are included in the red dotted box.
