(a)–(d) Time evolutions for the populations of the singly-excited state P_r(t) (left panels) and the doubly-excited state P_rr(t) (right panels). From top to bottom, as the ratio U_dd/Ω_eff increases (Ω_eff = 1.0 MHz and vary U_dd), the Rabi oscillations are in the regimes of (a) no blockade, (b) partial blockade, (c) partial blockade, (d) full blockade, respectively. The cases of Γ = 10 MHz (blue-solid) and Γ = 200 MHz (black-dashed) are presented.
