Suggested background knowledge

Being familiar with elementary mechanics, as well as with basic linear algebra and probabilities will be of help for students to better understand the topics, and to solve problems

Mission & Content Summary

MISSION

Quantum and statistical physics are the two pillars of modern physics. The scope of the course is to provide the basic conceptual and methodological tools which form the basis of quantum mechanics and statistical physics. The course will introduce the main concepts, provide the necessary mathematical formalism, and work out many examples of applications.
