Title: An Introduction to Conformal Field Theory in 2 + 1 Dimensions

Two lectures by Junchen RONG (CPHT)

Centre de Physique Théorique, École polytechnique
Salle de conférences Louis Michel
April 7 & 11, 2025 from 11:00 to 13:00

Abstract:
In this series of lectures, I will explore conformal field theories (CFTs) in 2 + 1 dimensions and the renormalisation group flows connecting them. I will begin by examining scalar CFTs, which correspond to Wilson-Fisher fixed points in 4− ε dimensions, focusing on their stability properties from a modern perspective. Following this, I will discuss 2 + 1 dimensional gauge theories with bosonic or fermionic matter. If time permits, I will also discuss the connections between these CFTs and quantum/statistical phase transitions.
