Figure 6

Dynamics of concurrence as a function of the dimensionless quantity Jt for different values of \(T_M\) by setting \(\kappa =0.05J\), \(B_0=0.6J\) and \(\Delta =0.5 J\). The initial state is \(|\Phi _3\rangle =\frac{1}{\sqrt{2}}\left[ |0,1\rangle -|1,0\rangle \right]\). The plots correspond to the symmetric coupling setting \((\varepsilon =0)\) (panels (a) and (b)) and asymmetric coupling setting \((\varepsilon =1)\) (panels (c) and (d)). Panels (a) and (c), refer to \(T_M=0.5J\), while panels (b) and (d) refer to \(T_M=2J\).
