'... an excellent textbook for a first encounter with quantum field theory and an essential reference for senior physicists. It presents the topic from a modern and streamlined perspective with beautiful and fresh explanations and clarifies many common misconceptions ... Thomas Banks is one of the deepest theoretical physicists and one of the best teachers in the field.' Nathan Seiberg, Princeton University 'After reading this book, I'll never teach field theory in the same way again. Banks provides a modern, insightful treatment of the basic structure of quantum field theory, including anomalies, solitons and instantons. Perhaps most remarkable is his treatment of renormalization and the renormalization group, which ... succeeds in presenting the conceptual framework ... while providing the reader with the tools necessary for practical calculations.' Michael Dine, University of California, Santa Cruz '... very approachable ...' The Observatory 'Modern Quantum Field Theory: A Concise Introduction is a very ambitious and in many respects successful book. ... Particularly appreciated was the modern treatment of the theory of renormalization, presenting the subject in a far more physical manner than many textbooks ... the reader who takes time to make a full study of it will end up better and more deeply informed than they will from a study of most other introductory texts on the subject.' The Observatory
Thomas Banks is Professor of Physics at the Santa Cruz Institute for Particle Physics (SCIPP), University of California, and NHETC, Rutgers University. He is considered one of the leaders in high energy particle theory and string theory, and was co-discoverer of the Matrix Theory approach to non-perturbative string theory.
