Contents:
Introduction -- The Landau theory -- Response of the system to external excitations -- General properties of Green's functions -- The structure of the elementary excitations spectrum -- Perturbation methods -- Interaction of two elementary excitations -- Generalization of perturbation methods to superfluids -- Appendices -- Notation -- References and literature -- Index --
Summary: Properties of Fermi liquids, both normal and superfluid, are dealt with in this new research monograph. The main physical features of these systems are analyzed, and the author sets forth in detail the field theoretical formalism developed in recent years. Chapter 1 is devoted to the phenomenological theory of normal Fermi liquids due to Landau; it introduces in a simple manner such important concepts as quasi particles and collective modes. Chapter 2 treats the response of these systems to an external probe. Chapters 3 and 4 introduce the field theoretical concept of "Green's functions" and discuss its structure in normal and superfluid liquids. Chapters 5 and 6 present the perturbation formalism in normal liquids; Chapter 7 extends it to superfluids. Important new materials includes a detailed account of the beautiful theory of Fermi liquids due to Landau; a detailed analysis of the perturbation techniques, including new material on the structure of the interaction operator; and an extension of the perturbation formalism to superfluids. Although many book survey a wide variety of many-body problems without much detail, this volume treats a single problem (Fermi liquids), analyzing the structure of the theory with special emphasis on the perturbation methods.
