The interaction of bodies blurs the concept of independent particles. This book presents a way of accommodating the interaction in ensembles of many interacting fermions, like electrons in solids, or H e 3 at low temperatures. The theory of interacting fermions at zero temperatures is described, and its application to the quasiparticle picture is thoroughly investigated, with the aim of relating Landau's theory of the normal Fermi liquid to the quantum-mechanical interaction effects. The reader should have a background knowledge of quantum mechanics, statistical physics and quantum-field theory. The book derives the phenomenological interaction function of the normal Fermi liquid from the underlying fermion interaction, and presents specific calculations of the relevant quantities. In particular, the validity of the quasiparticle concept is investigated, and quantitative limits are given. An estimation of the ground-state energy and the chemical potential is presented, which is a long-standing problem in this phenomenological theory.

Marian Apostol is a scientific researcher and Professor of Theoretical Physics in the Institute for Physics and Nuclear Engineering and the Institute of Atomic Physics, Magurele, Romania, where he has worked since 1972. He has published 150 papers on condensed matter, atomic and nuclear physics, quantum theories, statistical physics, elasticity, fluids, electromagnetism, and general and applied physics. He is the founder and editor of the Journal of Theoretical Physics and Antiphysical Review, and the author of several books of physics, including Twenty Lectures on Physics; Essays in Electromagnetism and Matter; Magnetic and Electric Resonance; Equations of Mathematical Physics; Theory of Quanta; Structure of Matter, Physical Kinetics, Statistical Physics, Radiation and Matter, Singular Equations of Waves and Vibrations.
