After successful completion of the course, students are able to comprehend the materials presented in the lecture and to draw conclusions from them, as well as to actively communicate the contents presented during the lecture.

One day these might lead to a quantum computer - or not. What seems to be certain is that chip design will become much more complex in the future, since quantum effects need to be accounted for. For example, two quantum dots which, individually, are in the Coulomb blockade regime (non-conducting) become both conducting even though the interaction between them is purely electrostatic. This is because of the effect coined after Jun Kondo, albeit in terms of a pseudo-spin associated with the two quantum dots. The aim of the Projektarbeit is a more thorough understanding of the recent, well-controlled experiments by means of perturbative and/or numerical renormalization group studies.
