Quantum Field Theory in Condensed Matter Physics [Paperback]

A new edition of a successful advanced text in condensed matter physics.This book is a course in modern quantum field theory for condensed matter physics. It includes a derivation of the path integral representation, Feynman diagrams and elements of the theory of metals including a discussion of Landau Fermi liquid theory. In later chapters the discussion gradually turns to more advanced methods used in the theory of strongly correlated systems. The book contains a thorough exposition of such non-perturbative techniques, as 1/N-expansion, bosonization (Abelian and non-Abelian), Conformal field theory and theory of integrable systems.This book is a course in modern quantum field theory for condensed matter physics.

Alexei Tsvelik also covers Landau Fermi liquid theory and gradually turns to more advanced methods used in the theory of strongly correlated systems. The book contains a thorough exposition of such non-perturbative techniques, as 1/N-expansion, bosonization (Abelian and non-Abelian), conformal field theory and theory of integrable systems.
