Qubits' entropy Sq (a) and concurrence Cq (b) as functions of dimensionless time tΔ for different values of the coupling g ∈ [0.40, 0.55]Δ and J = 0, near the critical point, computed through TDVP and DMRG. The dotted lines represent the DMRG equilibrium values corresponding to the TDVP dynamical values, shown as solid lines with markers specified in the legend. In panel (a), the horizontal black line indicates the maximum value of von Neumann entropy for a single qubit.
