We would like to point out that the time dependence of the correlation functions calculated in Ref. 31 was due to a steplike time dependence in (Formula presented) and the system was taken to be initially in equilibrium

A further peculiarity of Eq. (12) as compared to the calculations done in Refs. 29. 331 is that in the present case the Wick theorem leads to time-dependent Pfaffians

The entropy of a block of L spins and the scaling of it as a function of L was discussed in Ref. 20. Following the line of thought in Ref. 28, this quantity contained the more different types of entanglement the larger is L. We consider the case where A contains only a single site in order to study the conjecture in Ref. 28

This is in contrast to what should be observed, if the damping was related to the quantum critical point: it should depend on the size of the system in a way prescribed by the critical exponents of the system
