# Quantum Field Theory and Critical Phenomena: Fifth Edition

(International Series of Monographs on Physics) 5th Edition

by Jean Zinn-Justin (Author)

Introduced
as a quantum extension of Maxwell's classical theory, quantum
electrodynamics has been the first example of a Quantum Field Theory
(QFT). Eventually, QFT has become the framework for the discussion of
all fundamental interactions at the microscopic scale except, possibly,
gravity. More surprisingly, it has also provided a framework for the
understanding of second order phase transitions in statistical
mechanics.

few degrees to several hundred) and high energy
particle physics up to a TeV, altogether more than twenty orders of
magnitude in the energy scale.

Therefore, this text sets out to
present a work in which the strong formal relations between particle
physics and the theory of critical phenomena are systematically
emphasized. This option explains some of the choices made in the
presentation. A formulation in terms of field integrals has been adopted
to study the properties of QFT. The language of partition and
correlation functions has been used throughout, even in applications of
QFT to particle physics. Renormalization and renormalization group
properties are systematically discussed. The notion of effective field
theory and the emergence of renormalisable theories are described. The
consequences for fine tuning and triviality issue are emphasized.

This
fifth edition has been updated and fully revised, e.g. in particle
physics with progress in neutrino physics and the discovery of the Higgs
boson. The presentation has been made more homogeneous througout the
volume, and emphasis has been put on the notion of effective field
theory and discussion of the emergence of renormalisable theories.
