Can anyone suggest me a good reference for path integrals (QFT), apart from peskin.
joly said:Zee's Quantum Field Theory in a Nutshell is a great book to start on path integrals and QFT in general. (I stopped counting how many times I read it).
ChrisVer said:Well, that's not a place to say this, but... How can you judge a book from a 4 lecture/presentation on the topic by the author to a divergent audience??
DiracPool said:I think that's probably a better way than just judging the book by it's cover, don't you think?
Does this book discuss non-perturbative methods, gauge fixing, Gribov ambiguities and all that?dextercioby said:Bailin and Love - Introduction to Gauge Field Theory. Does QFT only in path-integral formalism.
The purpose of using path integrals in quantum field theory is to provide a mathematical framework for calculating the amplitudes of particle interactions. It allows for the calculation of probabilities for various particle interactions and is an essential tool in understanding the behavior of quantum systems.
Path integrals differ from other methods of calculating particle interactions, such as perturbation theory, in that they take into account all possible paths that particles can take in space and time. This includes paths that may not be captured by perturbation theory, making path integrals a more comprehensive approach.
Yes, path integrals can be used for all quantum field theories. However, they are particularly useful for non-perturbative calculations in theories where perturbation theory is not applicable, such as in quantum gravity or condensed matter systems.
"Beyond Peskin's Reference" provides a more comprehensive and detailed treatment of path integrals in QFT. It covers advanced topics such as non-perturbative effects, symmetries, and anomalies, which are not typically included in introductory texts on the subject.
Yes, there are several practical applications of path integrals in QFT. These include the calculation of scattering amplitudes, the study of phase transitions in condensed matter systems, and the development of quantum computing algorithms. Path integrals also have applications in other fields, such as statistical mechanics and string theory.
