After successful completion of the course, students are able to contrast Fermi- and non-Fermin-liquids, to explain Kondo physics, to describe unconventional superconductivity, to analyse properties of heavy fermion systems as well as to to identify relevant parameters.

This lecture deals with a particular class of intermetallic compounds exhibiting extraordinary low temperature proberties. Such properties are, e.g., effective electron masses exceeding those of free electrons up to 3 orders of magnitude. This behaviour influences, of course, most of the observable physical quantities like transport phenomena or thermodynamical properties. The primary interaction mechanism responsible for these observations is thought to be the Kondo effect. The ground state properties originated from this effect are usually described in terms of a Fermi-liquid. This lecture will give an overview on the rich variety of experimental results of highly correlated electron systems. Moreover, theoretical models such as the Anderson - or the Coqblin-Schrieffer model are introduced in order to account for the experimental findings. Recently observed phenomena like qunatum criticality, heavy fermion superconductivity or the non-Fermi-liquid ground state will also be discussed. MATHEMATICA is used in this lecture to perform different model calculations.

With the help of digital presentations the theoretical part of the lecture is explained. Blackboard notices support the slides.

An script is distributed during the lectures or can be downloaded at TISS. The first lecture will be given on Tuesday, March 10, 2020, 12:15, seminar room FH 7.OGC (red tower).

The subjects of the course are discussed orally.

Lecture notes for this course are distributed at each lecture or can be downloaded via TISS. 

Baisc lectures on solid state physics are very helpful.
