Quantum Many Body Systems and Strongly Correlated Electrons

Basic course given by Massimo Capone, Michele Fabrizio

Start: 09-10-2017 End: 21-12-2017 Room: 131
Schedule: Mon 8:30 - 11:00, Thu 8:30 - 11:00

Program

The basic course will present two cornerstone models of many-body physics: The Hubbard model and the Kondo model. We will use this model to introduce essential tools for many-body physics ranging from linear-response theory to Feynman diagrams.

Here follows the list of lectures. No lectures are scheduled on the week starting October 16 and on November 19, but a lecture is scheduled for Friday, 20.
