A classic from 1964, this monograph, translated from the original French, provides a detailed exposition of field theoretical methods as applied to zero-temperature Fermi liquids. The machinery of diagrammatic techniques is explained in detail, both for the ground state and for the Green's functions (propagators) that describe elementary excitations. Special attention is paid to the concept of quasiparticles in normal Fermi liquids, in continuity with those of the noninteracting gas. The phenomenological theory of Landau is justified from first principles. The extension of perturbation methods to superfluid systems is discussed in the last chapter. The book emphasizes methods and concepts more than specific applications: It is aimed at graduate students and at condensed matter physicists.

This book consolidates the older and more recent concepts on weakly-interacting fermions where traditional many-body techniques are adequate. Targeting primarily the advanced undergraduates and graduates, the author has included plenty of examples and problems from contemporary topics of research.

This book provides a detailed exposition of field theoretical methods as applied to zero temperature Fermi liquids. It is a product of a course taught in 1959–1960 at the University of Paris in the "Troisieme Cycle" of Theoretical and Solid-State Physics.

The physics of strongly correlated fermions and bosons in a disordered envi ronment and confined geometries is at the focus of intense experimental and theoretical research efforts. Advances in material technology and in low temper ature techniques during the last few years led to the discoveries of new physical of atomic gases and a possible metal phenomena including Bose condensation insulator transition in two-dimensional high mobility electron structures. Situ ations were the electronic system is so dominated by interactions that the old concepts of a Fermi liquid do not necessarily make a good starting point are now routinely achieved. This is particularly true in the theory of low dimensional systems such as carbon nanotubes, or in two dimensional electron gases in high mobility devices where the electrons can form a variety of new structures. In many of these sys tems disorder is an unavoidable complication and lead to a host of rich physical phenomena. This has pushed the forefront of fundamental research in condensed matter towards the edge where the interplay between many-body correlations and quantum interference enhanced by disorder has become the key to the understand ing of novel phenomena.
