This short series of lectures introduces Functional Renormalization Group methods, both perturbative and non-perturbative, and applies them to the study of Universality Classes of Critical Phenomena in arbitrary dimension.
The course will also show (with explicit computations) the power and simplifications that the “functional constraint” offers in performing a wide array of Quantum Field Theory computations and is thus recommend to Master and PhD students in Theoretical Physics.
Introduction: Universality and Renormalization Group methods
Functional Perturbative RG: Universality in the epsilon-expansion
Functional Non-Perturbative RG: Wetterich Equation and Scaling Solutions
Multi-component world: towards a classification of Universality Classes in arbitrary dimension
