Condensed Matter Theory

Material

• Script to the lecture

• Script 18 October 2023

• Group and phase velocity

• The Mathematica notebook shows the time evolution of a Wave-packet. The gif file is the result and shows the propagation of the density and of the wave with different velocities. The script in chapter 4.2.3 discusses the group and phase velocity

• Group theory

• Here you can find the script of my and Martin Brass lecture on group theory. I furthermore added a chapter from a textbook by Ballhausen. The book chapter is not mathematical rigorous, but shows a very quick introduction to the use of group theory.
