Office hour (via zoom): Thursdays 13:00-14:00

This course will give an introduction to effective field theories and the physics of many-body systems, with special attention to modern concepts and to applications ranging from cold atoms to nuclei, neutron stars and condensed matter systems.

Announcements

Zoom link for lectures and office hour, as well as links to video recording will be sent via TUCAN messages.
