Figure 3

Dynamics of concurrence as a function of the dimensionless quantity Jt for different values of \(T_M\) by setting \(\kappa =0.05J\), \(B_0=0.6 J\) and \(\Delta =0.5 J\). The initial state is \(|\Phi _1\rangle =|00\rangle\). The plots correspond to the symmetric coupling configuration, i.e., \(\varepsilon =0\) (panels (a) and (b)) and asymmetric coupling configuration, i.e., \(\varepsilon =1\) (panels (c) and (d)). Panels (a) and (c), refer to \(T_M=0.5J\), while panels (b) and (d) refer to \(T_M=2J\).
