Term: 1

Start: 05-10-2021 End: 19-11-2021 Room: 131

Credits: 3

Schedule: Tue 11:00 - 13:00, Wed 11:00 - 13:00


This is the website for the first half of the "basic" many-body course. The course has also a follow-up which develops more deeply the theory of strongly correlated electron system and its relation with high-Tc superconductivity.

The basic course introduces some of the main standard tools to study many-particles systems in the concrete case of the Hubbard model and for the study of superconductivity and magnetism.
