Book Description

The unique physics of many-particle systems, in particular those that are dominated by correlation effects, is the subject of this textbook, Theoretical Physics 9: Fundamentals of Many-body Physics (2nd Edition), which is available in PDF format. It creates contemporary approaches to treating such systems and explains how those approaches might be applied through a number of relevant exercises, the majority of which are from the field of solid state physics. This book is prepared in a tutorial format that is suited for individuals who wish to study many-body theory and eventually use this to perform research work in this subject. The target audience for this book is those who want to learn many-body theory. The tasks, along with complete solutions for evaluating one’s performance, help to develop one’s grasp of the fundamental aspects of many-particle systems.

This updated and revised second edition includes new chapters on the finite-temperature Matsubara formalism. These chapters cover topics such as the Dyson equation, the Hartree-Fock approximation, the second order perturbation theory, the Hubbard model, quasi particles, the Jellium model, spin density waves, Fermi liquids, and multi particle Matsubara functions.

This book is the final installment in the excellent Theoretical Physics series, and it is going to be an extremely helpful resource for both advanced students and academics.
