Abstract: International team led by Prof. Tagantsev from EPFL Lausanne [A.T. et al, Nature Comm 10.1038/ncomms3229] has recently reported that the mystery of antiferroelectricity of lead zirconate is resolved. Which experiments and theories constitute the content of this paper? Is our recent IR and Raman spectroscopic studies in agreement with the picture drawn in this paper? Through a somewhat extended version of my talk "Phonon dispersion of Pb(ZrTi)O3 unfolded" from DyProSo symposium in Sept 2013, I would like share with you my analysis of these and related questions.
