Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...

I'm aware of Sidney Coleman's 1975/76 sequence of 54 lectures on Quantum Field Theory. Are there any other high-quality QFT lecture series available online?

Oct 23, 2021 · A modern approach to quantum field theory, which axiomatizes the assignment of algebras of observables, is " Algebraic Quantum Field Theory ", based on the "Haag-Kastler …

Dec 19, 2023 · I am currently self studying QFT using Schwartz's book but I am unable to find any solutions to the exercises. Does anyone know if a solution manual exists for this book or if …

Dec 29, 2015 · No book on QFT is easy to read but the quantum field theory book by Weinberg is the entrance that explains most of the terms in a clear way. You need as background some …
