FIELD THEORY OF CONDENSED MATTER AND ULTRACOLD GASES - VOLUME 1Author(s): Nicolas Dupuis\nFormat: Hardback\nPublisher: World Scientific Europe Ltd, United Kingdom\nImprint: World Scientific Europe Ltd\nISBN-13: 9781800613904, 978-1800613904\nSynopsis\nThis book provides a pedagogical introduction to the concepts and methods of quantum field theory necessary for the study of condensed matter and ultracold atomic gases. After a thorough discussion of the basic methods of field theory and many-body physics (functional integrals, perturbation theory, Feynman diagrams, correlation functions and linear response theory, symmetries and their consequences, etc.), the book covers a wide range of topics, from electron gas and Fermi-liquid theory to superfluidity and superconductivity, magnetic instabilities in electron systems, and dynamical mean-field theory of Mott transition. The focus is on the study of model Hamiltonians, where the microscopic physics and characteristic energy scales are e.
