Penelope McRedmond,Gillian Wyliethe next lecture. The Landau theory is due to Dave Moncton and myself.. The Landau theory approach is especially powerful in the discussion of position-dependent or time-dependent properties. We don’t have an adequate dynamical theory yet and I will discuss only the static Landau theory.

https://doi.org/10.5822/978-1-61091-174-0st useful technique. Its wave-vector resolution is of the order of 5×10. Å., which is 10. times better than inelastic neutron scattering; such a high resolution is needed for an unambiguous analysis of the eigenfrequencies because of the considerable dispersion near the distortional wavevector.

Structural Phase Transitions and Superconductivity in A-15 Compounds,nductivity arrests the progress of the transformation. The tetragonal distortions are relatively small, (c/a-1) ≈ 2.2 × 10.3 and with Ac/c ∿ -2Δa/a so that there is little change in volume from the cubic state. Structural domains (of differing c axes orientations) occur below T..

Theory of Jahn-Teller Transitions,self in bands of collective vibronic modes arising from transitions between low-lying vibronic levels of the JT complexes, and an analysis of the collective dynamic behaviour requires a thorough understanding of the vibronic excitations of a single JT complex.
