Elementary Excitations in Crystalline Solids,e a crystalline structure, i.e. they are distinguished by a long-range order characterized by a periodic arrangement of atoms in a 3D lattice. In this chapter we present the model describing crystalline materials, and the most often encountered elementary excitations that can build in them.

Optical Transitions,ween the wavelength . of the electromagnetic radiation and the scale of the internal inhomogeneity of the solid. If these two parameters are comparable, light scattering occurs; if . is much larger than the scale of internal inhomogeneity, the electromagnetic field propagates as in a homogeneous med

Optical Properties of Impurities in Solids,optical spectra of sharp lines due to transitions between different discrete levels of the dopants or between the level of the dopants and the bands of the host material. The first problem is to calculate the energy levels of a dopant atom or ion inside a host. From the point of view of group theory

Bulk Materials,ither on the study of quite exotic materials, or on finding suitable and relatively simple analytical formula for the description of bulk materials. Of importance is also the investigation of anharmonic properties, isotope effects, and in compounds the dependence of several parameters on the concent

Low-Dimensional Structures,ation of energy levels. Low-D structures are commonly (but not exclusively) made from alternating layers of different semiconductors, in which case they are called low-D semiconductor heterostructures. If the width of the layers of low-D semiconductor heterostructures is smaller than the mean free p

Optical Properties of High-Temperature Superconductors, heavy-fermion materials such as UPt.. These materials are superconducting at temperatures not exceeding 23.2 K; the normal state, stable at higher temperatures, is separated from the superconducting state by a second-order phase transition.
