In theoretical physics quantum field theory (QFT) is a theoretical framework that combines classical field theory special relativity and quantum mechanics xi and is used to construct physical models of subatomic particles (in particle physics) and quasiparticles (in condensed matter physics).. QFT treats particles as excited states (also called quanta) of their underlying fields which are In physics a field is a physical quantity represented by a number or tensor that has a value for each point in space and time. For example on a weather map the surface wind velocity is described by assigning a vector to each point on a map. Each vector represents the speed and direction of the movement of air at that point.Following on from the successful first (1984) and revised (1993)editions this extended and revised text is designed as a short andsimple introduction to quantum field theory for final year physicsstudents and for postgraduate students beginning research intheoretical and experimental particle physics.
Quantum Mechanics with Basic Field Theory is an innovative textbook for a two semester graduate course that provides an excellent coverage of the fundamentals interspersed with their relevance to striking modern discoveries.This note deals with modern applications of quantum field theory with emphasize on the quantization of theories involving scalar and spinor fields.All chapters are pedagogically brilliant Physics from Symmetry by J. Schwichtenberg a pedagogic masterpiece BookWebsite Aim . This book and this website aim to make learning and teaching quantum field theory (QFT) easier and thus more efficient and fulfilling.
