The concurrence-time function for an individual pair (a) (2, 3) and (b) (5, 6). In fact these plots shows the dependency of maximum entanglement on J values shared in discrete pairs. In both of plots dotted lines corresponds to \(J=-0.25\), dotdash lines addresses \(J=-0.5\), dashed lines matches to \(J=-0.75\) and finally solid lines is associated with \(J=-1.0\). The maximum entanglement for all J values is the same for pairs (2, 3) in panel (a). This rule also holds true for pair (5, 6) in panel (b). This phenomenon is generalizable for other pairs. (c) The time derivative of concurrence \((\frac{\partial C_{m,m+1}}{\partial t})\) for pair of (3, 4) and (d) for pair of (5, 6). They are representative other pairs and mimic their behaviors.
