Graduate Texts in Physics,1868-4521Includes index.3-319-28171-2 From Particles to Fields -- Disturbing the Vacuum -- From Fields to Particles -- Real Life I: Interactions -- Real Life II: Fermions and QED -- A Potpourri of Problems.This book describes, in clear terms, the Why, What and the How of Quantum Field Theory. The raison d'etre of QFT is explained by starting from the dynamics of a relativistic particle and demonstrating how it leads to the notion of quantum fields. Non-perturbative aspects and the Wilsonian interpretation of field theory are emphasized right from the start. Several interesting topics such as the Schwinger effect, Davies-Unruh effect, Casimir effect and spontaneous symmetry breaking introduce the reader to the elegance and breadth of applicability of field theoretical concepts. Complementing the conceptual aspects, the book also develops all the relevant mathematical techniques in detail, leading e.g., to the computation of anomalous magnetic moment of the electron and the two-loop renormalisation of the self-interacting scalar field. It contains nearly a hundred problems, of varying degrees of difficulty, making it suitable for both self-study and classroom use. .Graduate Texts in Physics,1868-4521Particles (Nuclear physics)Quantum field theoryMathematical physicsElementary Particles, Quantum Field TheoryMathematical PhysicsParticles (Nuclear physics)Quantum field theory.Mathematical physics.Elementary Particles, Quantum Field Theory.Mathematical Physics.530.143Padmanabhan Thanuauthttp://id.loc.gov/vocabulary/relators/aut49516MiAaPQMiAaPQMiAaPQBOOK9910254628603321Quantum Field Theory2528328UNINA
