Neutron Scattering Studies of Electron-Phonon Interactions,This review is an attempt to summarize the areas in which neutron scattering has been used in studying electron-phonon interactions, and to display some of the key results. The examples chosen reflect the interests of the author and represent in no way a complete survey of the subject.

Synthesize

Charge Density Waves in Layered Compounds,The work I will describe was performed in collaboration with many others including J. D. Axe, S. Mahajan, D. E. Monoton, J. A. Wilson and J. V. Waszczak. While it is impossible to cover all the interesting phenomena observed in layered compounds, I will reference these phenomena where appropriate.

Symmetry Classification of Modulated Structures,In a normal crystal, symmetry is defined by a group of operations, each of these belonging to the much larger group of all proper and improper movements. The symmetry translations . where . (n. = integer, i = 1,2,3) constitute an invariant subgroup of every crystal symmetry group.

Stricture

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 ele

Jessica Ellis,Quinta Johnson,Danielle Thomas anything. That goal has been pretty well achieved in superconductivity. We are still struggling with the theory of charge density waves. The way that one progresses in solid state physics is to compute the properties of a theoretical model, compare the predictions with experiment, and modify the mo
