Jan 30, 2017 · In quantum field theory an electron traversing space time is described by a quantum mechanical wave packet (which means that what "waves" is the probability of …

4 days ago · Quantum Field Theory (QFT) is the theoretical framework describing the quantisation of classical fields which allows a Lorentz-invariant formulation of quantum mechanics. QFT is …

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 …

Quantum field theory (QFT) is a theoretical framework for constructing quantum mechanical models of subatomic particles in particle physics and quasiparticles in condensed matter …

Aug 17, 2023 · 20 Every time I read about quantum field theories, I wrongly assume and associate the theory to the Standard Model, that is, our current theory of particles and …

Aug 21, 2023 · When we measure the wave-functional, will it collapse to a certain field configuration, which we then interpret as some collection of particles with certain momenta? …

Apr 7, 2023 · The "operator algebra" language isn't really one I'm super familiar with, but roughly (skimming over renormalization), to do quantum field theory you take your favorite approach to …
