Responsible coordinator of the module PH2245 is Antonio Vairo.

Content, Learning Outcome and Preconditions

Content

The lecture course provides an introduction to effective field theories (EFTs) and renormalization techniques with applications ranging from high energy to atomic physics. The course consists in three parts: (1) basics of EFTs and renormalization group; (2) introduction to the Heavy Quark Effective Theory (HQET); (3) non-relativistic EFTs and applications to atomic physics.

Learning Outcome

The student will learn how to build effective field theories from identifying the relevant degrees of freedom and symmetries to renormalize them.  The basics will be broad and applicable to all effective field theories. Some specific EFTs will be worked out in more detail.

Preconditions

Quantum Mechanics 1 + 2 and some basic knowledge of Quantum Field Theory and the Standard Model.

Module Exam

Description of exams and course work

In a written exam of 60 minutes the learning outcome is tested using comprehension questions and sample problems.

In accordance with §12 (8) APSO the exam can be done as an oral exam. In this case the time duration is 25 minutes.
