Numerical plot of the maximal squeezing factor as a function of the effective atomic resonant frequency ω₀. Insert: numerical plot of the time-dependent squeezing factor , when ω₀/q = 0.3. In both subfigures, the initial states, the anisotropic parameter, and the atomic number are chosen as |J_z = −j⟩, χ = −1, and N = 100, respectively.
