The dynamical properties of solids have recently attracted renewed interest in connection with the increasing understanding of phase transitions and re- lated phenomena. In particular, soft modes or, …

This phonon atlas presents a collection of phonon-dispersion and density-of- states curves of more than a hundred insulating crystals. It grew out of an appendix to a handbook article on phonon spect …

The investigation of the properties of nonlinear systems is one of the fast deve- loping areas of physics. In condensed matter physics this ‘terra incognita’ is approached from various starting point …
