It is recommended to have followed the course of introduction to Quantum Field Theory of the Master, or at least basic courses on Quantum Field Theory during the undergrate courses.
The main goal of the course is twofold: 1) on one side, to develop a different approach to Quantum Mechanics and Quantum Field Theory based on the Path Integral approach and 2) on the other, to understand and be proficient in the renormalization of a theory. This is a fundamental requisite to arrive to any physical result involving loop diagrams. Besides understanding the concept and renormalization procedure we will focus on its interaction with symmetries and we will conclude by establishing the renormalization group equations.
Functional Methods
1.1 Path Integral in Quantum Mechanics.
1.2 Functional Quantization and Path Integral in Quantum Field Theory
1.3 Symmetries in the functional formalism language
Renormalization Theory
2.1 Ultraviolet Divergences, conceptual meaning.
2.2 Classification of theories according to their renormalization properties
2.2 Renormallzed perturbation theory
Renormalization and symmetry
3.1 Spontaneus Symmetry Breaking and linear sigma model: how they should be renormalized.
Aspects of non abelian gauge theories
Renormalization Group Equations
The course will be organized in teaching lectures where the theory of Path Integrals and Renormalization will be developed in full detail.
Students will be encouraged to ask questions during the theory lectures but they also will be asked questions.
Along the lectures a list of problems will be proposed.
It is recommended to follow the course daily including work at home to fully profit and completely understand the concepts discussed.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

The evaluation of the course will consist of three blocks:
- A written exam that will count 50% of the note, and with the right to a recovery exam (for 50%).
- Deliveries of problems will be proposed that will count the remaining 40% of the mark.
- Attendance and active participation in class will count 10% of the mark.
