Comment on 'Ab initio evidence for nonthermal characteristics in ultrafast laser melting'

摘要

In the Comment on our original publication [Phys. Rev. B 94, 184310 (2016)], Zier et al. claimed that no melting is observed in real-time time-dependent density functional simulations and there are several inconsistencies in our paper. In this Reply we demonstrate that the "correct" melting behavior indicated in the comment by Zier et al., which was adopted from empirical concept of thermal melting, is inappropriate and conflicts with ultrafast experiments on nonthermal laser melting. The barrier calculated from phonon spectra is a static barrier and different from the dynamic ones, causing no inconsistency. We confirm that nonthermal melting behaviors and interpretation in the original paper are credible.
