A Control View to Vision Architectures,PA theory gives an excellent description of both the static and dynamic behaviour of these systems. Within this theory the momentum dependences of the effective electron-phonon coupling parameters have been derived from the measurements on PrA1O. and TmVO., and in the latter case an excellent agreem

Stephanie Margarete Mueller,Martin Grunwaldrces involved, then to discuss the possibility of small amplitude phase changes arising in perfect crystals as a weak modulation of the simpler structure. This modulation can be viewed as due to a phonon mode of the simpler structure becoming soft; and conditions for this to occur through strong electron-phonon coupling are recalled.

Local Jahn-Teller Effect at a Structural Phase Transition,the critical enhancement of the local JT-effect caused by the vibronic coupling to the soft mode of a structural phase transition of the host crystal. Furthermore, we study the temperature-dependence of the strain field around the JT-centre induced by the local JT-effect.
