Time evolution of L(t) (dashed plots), U(t) (dashed dotted plots), M(t) (upper solid plots) and N(t) (solid plots) for large coupling case \(J=0.1\tilde{g}\) with different decay rate \(\chi =0.0\) in (a) and \(\chi =0.1\tilde{g}\) in (b), where the NVD are prepared initially in correlated state, \(|\Psi (0)\rangle =\frac{1}{\sqrt{2}}[|e_{1}g_{2}\rangle +|g_{1}e_{2}\rangle ]|0_{1}0_{2}\rangle\).
