The course has a team set up in MS Teams under the name Advanced Quantum Field Theory (2025/26/1), available only for registered students. The access code is sent via Neptun.
Classes
There are 2x45 minutes of lectures every week, supplemented by an exercise class in the form of student seminars. The language of the course is English.
Aim and scope
This course builds upon Quantum Field Theory (BMETE15MF65) and discusses advanced topics such as
(i) advanced renormalization;
(ii) advanced functional techniques, non-perturbative methods and their applications;
(iii) quantisation of non-Abelian gauge theories;
(iv) symmetries and their breaking;
(v) effective action, effective potential;
(vi) instantons and quantum tunneling.

Evaluation
Oral examination. During the exam, students can consult their lecture notes for the details of lengthy derivations, but are expected to be able to explain the underlying concepts and considerations in detail.
