Quantum field theory 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 Understand Physics Through Quantum Field Theory A book that finally gets it right Brooks presents the news about quantum field theory in a non technical but accurate manner His explanatory technique of using different colors to represent different fields is a stroke of pedagogical genius. David Tong Quantum Field Theory University of Cambridge David Tong Lectures on Quantum Field Theory These lecture notes are based on an introductory course on quantum field theory, aimed at Part III i.e masters level students. Quantum Field Theory University of Cambridge Recommended Books and Resources M Peskin and D Schroeder, An Introduction to Quantum Field Theory This is a very clear and comprehensive book, covering everything in this course at the Local quantum field theory The Haag Kastler axiomatic framework for quantum field theory, introduced by Haag and Kastler , is an application to local quantum physics of C algebra theory Because of this it is also known as algebraic quantum field theory AQFT.The axioms are stated in terms of an algebra given for every open set in Minkowski space, and mappings between those.
