The chapter provides an overview of the third edition of "Many-Particle Physics" by Gerald D. Mahan, published by Springer Science+Business Media, LLC. The book is part of the "Physics of Solids and Liquids" series, edited by a team of experts from various universities. The current volumes in the series cover topics such as crystalline semiconducting materials, electron correlation in molecules, electronic excitations at metal surfaces, and quantum transport in semiconductors. The preface highlights the evolution of the book, which is updated every ten years to reflect the latest developments in many-body theory. The third edition includes new sections on Bethe lattice, different mean-free-paths, Hubbard model, Coulomb blockade, Landauer transport, and the Quantum Hall effect. The author also addresses the challenge of covering high-temperature superconductivity, where theoretical understanding remains uncertain, and provides a balanced treatment of experimental results and theoretical models. The content of the book is structured into several chapters, covering introductory material, Green's functions at zero and nonzero temperatures, exactly solvable models, homogeneous electron gas, strong correlations, electron-phonon interaction, dc conductivities, optical properties of solids, superconductivity, and superfluids. Each chapter delves into specific topics with detailed explanations and examples, making it a comprehensive resource for students and researchers in the field of many-body physics.The chapter provides an overview of the third edition of "Many-Particle Physics" by Gerald D.
