Fig. 2

The plots illustrate the influence of detuning parameters (\(\Delta\)) and the nonlinearity parameter (\(\chi\)) on the time evolution (scaled time \(\lambda t\)) of the five-level atom and four-level atom captured by linear entropy with the fixed value of \(k=1\). Plot (a) depicts the linear entropy when \(\Delta = \chi = 0\), while plot (b) illustrates the scenario when \(\Delta = 5\) and \(\chi = 0\). Additionally, plots (c) and (d) showcase the linear entropy for the cases where \(\Delta = 0\), \(\chi = 0.5\) and \(\Delta = 5\), \(\chi = 0.5\) respectively.
