The research report contains all activities of the institute of physics of 2011. 2011 was another successful year for the Institut für Physik both in teaching and research. In this year, the first students finished the new bachelor course in physics and started their master studies. Most of them obtained very good results in the exams and B.A. thesis research, demonstrating that during adaption of the new system of academic degrees the high level of the internationally renown Diplomphysiker course could be maintained. Also, the students in our bachelor courses computational science as well as sensors and cognitive psychology made very good success. The latter, truly innovative course - which is unique in Germany - was very well received. The first students finished their second year.
