Synopsis:
A unique approach to quantum field theory, with emphasis on the principles of renormalization Quantum field theory is frequently approached from the perspective of particle physics. This book adopts a more general point of view and includes applications of condensed matter physics. Written by a highly respected writer and researcher, it first develops traditional concepts, including Feynman graphs, before moving on to key topics such as functional integrals, statistical mechanics, and Wilson′s renormalization group. The connection between the latter and conventional perturbative renormalization is explained.
Quantum Field Theory is an exceptional textbook for graduate students familiar with advanced quantum mechanics as well as physicists with an interest in theoretical physics. It features:
∗ Coverage of quantum electrodynamics with practical calculations and a discussion of perturbative renormalization
∗ A discussion of the Feynman path integrals and a host of current subjects, including the physical approach to renormalization, spontaneous symmetry breaking and superfluidity, and topological excitations
∗ Nineteen self–contained chapters with exercises, supplemented with graphs and charts
Review:
"The description of low dimensional systems, e.g. one–dimensional conductors, is added. Moreover, in the appendix C, Polchinski′s renormation equation is derived, solved and applied to the asymptotically free scalar field." ( Zentralblatt MATH, 2010)
"Written by a highly respected textbook writer and researcher, this book has a more general scope and adopts a more practical approach than other books." ( ETDE – Energy Database, 2010)
