"Ultrafast Structural Dynamics of Polar Solids Studied by Femtosecond X-Ray Diffraction" T. Elsaesser, C. von Korff Schmising, N. Zhavoronkov, M. Bargheer, M. Woerner, M. Braun, P. Gilch, W. Zinth, I. Vrejoiu, D. Hesse, M. AlexeUltrafast Phenomena XVI, Springer Series in Chem. Physics 92, Eds. P. Corkum, S. De Silvestri, K.A. Nelson, E. Riedle und R.W. Schoenlein, Springer-Verlag, Berlin (2009) 101-103 Abstract: We discuss recent progress in ultrafast x-ray diffraction, addressing photoinduced structural dynamics in ferroelectric superlattices and polar molecular crystals. Elongations of coupled phonon modes affecting ferroelectric polarizations and structural changes connected with the solvation of molecular dipoles are determined quantitatively.
