Many-body theory of condensed matter systems : an introductory course / Michael G. Cottam, Zahra Haghshenasfard.

By: Cottam, Michael G [author.].
Contributor(s): Haghshenasfard, Zahra, 1978- [author.].
Material type: materialTypeLabelBookPublisher: Cambridge : Cambridge University Press, 2020Description: 1 online resource (xiv, 274 pages) : digital, PDF file(s).Content type: text Media type: computer Carrier type: online resourceISBN: 9781108762366 (ebook).Subject(s): Many-body problem | Condensed matter -- Mathematical models | Geometric quantization | Green's functionsAdditional physical formats: Print version: : No titleDDC classification: 530.4/1 Online resources: Click here to access online
Contents:
Introduction to second quantization -- Time evolution and equations of motion -- Formal properties of Green's functions -- Exact methods for Green's function -- Green's functions using decoupling methods -- Linear response theory and Green's functions -- Green's functions for localized excitations -- Diagrammatic perturbation methods -- Applications of diagrammatic methods.
Summary: In this primer to the many-body theory of condensed-matter systems, the authors introduce the subject to the non-specialist in a broad, concise, and up-to-date manner. A wide range of topics are covered including the second quantization of operators, coherent states, quantum-mechanical Green's functions, linear response theory, and Feynman diagrammatic perturbation theory. Material is also incorporated from quantum optics, low-dimensional systems such as graphene, and localized excitations in systems with boundaries as in nanoscale materials. Over 100 problems are included at the end of chapters, which are used both to consolidate concepts and to introduce new material. This book is suitable as a teaching tool for graduate courses and is ideal for non-specialist students and researchers working in physics, materials science, chemistry, or applied mathematics who want to use the tools of many-body theory.
