Figure 3
Eigenenergy spectrum of the system’s Hamiltonian with off-resonant detuning. Eigenenergies of the Hamiltonian (2) as a function of the probe-field detuning Δ p at different values of the tunneling couplings strength and the frequency difference ω43: (a) Te1 = Te2 = Γ4/5, ω43 = ±Γ4/5, and (b) Te2 = 2Te1 = Γ4 = 10 μeV, ω43 = ±Γ4, with ω42 = 0 and Ω p  = 10−2 Γ4. The red dashed loops are used to highlight the anticrossing points.
