Dimensionless (a,c) real \(\texttt {Re}(\omega )\) and (b,d) imaginary \(\texttt {Im}(\omega )\) parts of eigenfrequencies \(\omega\) for the DIS complex network vs. population inversion logarithm \(\log (\sigma _i)\) within approach (3), (4) that implies \(\bar{\sigma }=\sigma _{i}\simeq \sigma _{0,i}\). The avatar–user coupling strength is \(g = 1\) for (a,b), and \(g_i = g\sqrt{k_i}\) for (c,d). The other parameters are: \(N = 100\), \(\kappa =1\), \(\Delta _i\in [-0.1;0.1]\) and \(\Gamma _i\in [0.2;1.8]\) are random and uniformly distributed variables.
