“The book arises from EPFL lectures carried out in 2012. … certainly recommended for students which are interested in Conformal Field Theory. … it is well exposed, well written, and contains the argumentation in the level of its necessity.” (J. M. Hoff da Silva, zbMATH, Vol. 1365.81007, 2017)
EPFL Lectures on Conformal Field Theory in D ≥ 3 Dimensions
von Slava RychkovThis primer develops Conformal Field Theory (CFT) from scratch, whereby CFT is viewed as any conformally-invariant theory that describes a fixed point of a renormalization group flow in quantum field theory.
The book is divided into four lectures: Lecture 1 addresses the physical foundations of conformal invariance, while Lecture 2 examines the constraints imposed by conformal symmetry on the correlation functions of local operators, presented using the so-called projective null cone – a procedure also known as the embedding formalism. In turn, Lecture 3 focuses on the radial quantization and the operator product expansion, while Lecture 4 offers a very brief introduction to the conformal bootstrap.
Derived from course-based notes, these lectures are intended as a first point of entry to this topic for Master and PhD students alike.
