quantities in solids which are direction-dependent. In the simplest
cases vectors can be used, in the more complicated cases tensors of
various "ranks" are required. Examples for tensors of rank 2 are
conductivity, stress and strain, tensors of rank 4 are the quantities
needed for the description of elastic properties of solids. It is shown
how different vectorial and tensorial properties depend on the crystal
symmetry and how they can be calculated on the basis of
density-functional theory. Continuing along these lines the second part
of the course (by R. Eibler) is concerned with lattice vibrations
("phonons"). These are important, because they provide information on
the (vibrational) stability of solids and make it possible to calculate
the temperature dependence of the thermodynamic functions caused by the
lattice vibrations.
The last part of the lecture (by R. Podloucky) deals with the basics of
chemical bonding. Starting with a short discussion of the Schödinger
equation and its formulation in the framework of density-functional
theory, the thermodynamic and quantum-mechanical stabilization is
defined. The course ends with a short discussion of covalent bonding.Assessment of performance: oral exam
