Quantum field thory is a fundamental branch of theoretical physics, which in the last 20 years, has led to spectacular progress in our understanding of phase transitions and elementary particle physics.

This textbook emphasizes the underlying unity of the concepts and methods used in both domains, and presents in clear language topics such as the pertubative expansion, Feynman diagrams, renormalization, and the renormalization group.

It contains detailed applications

of critical phenomena to condensed matter physics, such as the calculation of critical exponents and a discussion of the XY model.

Applications to particle physics include quantum electrodynamics and chromodynamics, electroweak interactions, and lattice gauge theories.

The book is based on courses given over several years on statistical mechanics and field theory, and is written at graduate level.

It attempts to guide the reader through a somewhat difficult and sometimes intricate subject.

Further it is intended to lead the student up to the level of more advanced textbooks and research articles.

A large number of problems are given to measure the reader's understanding.

Reviews for Quantum and Statistical Field Theory

<br> [An] excellent book on field theory written from a modern standpoint and using a mathematical language (that of 'functional methods') appropriate to this standpoint. A superior text. Bellac's book surveys the whole field, but is particularly good on the physics of condensed matter. It is written in a very clear way. He covers a lot of ground, but in such a way that a beginning research student can learn about topics as diverse as the ising model, the renormalization group, path integral methods, and non-abelian gauge field theories. In fact, the earlier sections of the book should accessible to final-year undergraduates in theoretical physics. The book is well planned, carefully written, and pedagogically sound. -- <p><br> Good undergraduates, graduate students, teachers at different levels, and curious scientists are among the potential readers of this very interesting book. --Journal of Statistical Physics<p><br>
