Inelastic Interactions

An important part of condensed matter physics in recent years has involved detailed study of inelastic interactions between swift electrons and condensed matter surfaces. Here we will review some aspects of such interactions.Surface excitations have long been recognized as dominant in determining the exchange-correlation energy of charged particles outside the surface. Properties of surface and bulk polaritons, plasmons and optical phonons in plane-bounded and spherical systems will be discussed from the viewpoint of semiclassical and quantal dielectric theory. Plasmons at interfaces between dissimilar dielectrics and in superlattice configurations will also be considered.

Dynamical Properties

This paper traces the development of the study of the dynamical properties of the semimetallic actinide compounds that have a NaCl crystal structure (monopnictides and monochalcogenides) from the first experiment with a triple-axis spectrometer at Chalk River National Laboratory in 1976. The important realization that the excitations could be overdamped even in an ordered magnetic material, such as UN, because of the interaction between the 5f and conduction electrons remains one of the unique aspects of the physics of these materials. Later experiments on UTe and the transuranium material PuSb are discussed, together with the theoretical concepts that have allowed these results to be understood in terms of the hybridization between the 5f and conduction electrons.
