• ☕     7/4/2025 & 11/4/2025, 11:00-13:00, à la Salle de conférence Louis Michel, CPhT, École polytechnique

I will give two lectures on "An Introduction to Conformal Field Theory in 2 + 1 Dimensions".  

Abstract: In this series of lectures, I will explore conformal field theories (CFTs) in 2+1 dimensions and the renormalization 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.

Handwritten lecture notes can be downloaded here.
