Er,... you said you're trying to study QFT using P&S. Do you mean you're just readingkvl said:I'm trying to study QFT using P&S book. Now I'm on the chapter 13 but I feel that I'm rather bad at solving practical problems on QFT and QED. Could anyone suggest a good source of problems (preferably with solutions) on QFT and QED (near the level of P&S ch. 1-13) to practise ?
On the first reading I've solved approx. one exercise from each chapter, but now I'm solving the remaining ones. And of course I've repeated some of the calculations in the text myself.strangerep said:Er,... you said you're trying to study QFT using P&S. Do you mean you're just reading
through P&S, or have you actually worked through every line in the text pen-in-hand?
(Some of the steps are non-trivial). And have you solved all the exercises in P&S so far?

on the MIT website.]

QED (Quantum Electrodynamics) and QFT (Quantum Field Theory) are both theoretical frameworks used to describe the interactions between particles and fields. The main difference is that QED specifically deals with the interactions between electrically charged particles, while QFT is a more general framework that can be applied to all fundamental forces. QED is a subset of QFT, focusing specifically on the electromagnetic force.
QED and QFT have been used to successfully predict and explain a wide range of phenomena in particle physics, such as the behavior of electrons, positrons, and photons. These theories have also been applied in other fields, such as condensed matter physics, where they have been used to study the behavior of materials at a microscopic level.
One of the main challenges in studying QED and QFT is the complexity of the mathematics involved. These theories use advanced mathematical concepts such as quantum field theory, perturbation theory, and renormalization. Another challenge is that these theories are currently not unified with other fundamental forces, such as the strong and weak nuclear forces.
The Standard Model is a theoretical framework that describes the fundamental particles and their interactions through three of the four known fundamental forces (electromagnetic, weak, and strong). QED and QFT are both important components of the Standard Model, providing the theoretical basis for the electromagnetic force and the behavior of particles at a microscopic level.
Yes, there is ongoing research in QED and QFT to further refine and improve these theories. Some current areas of research include efforts to unify QED and QFT with the other fundamental forces, as well as exploring the potential for these theories to explain phenomena beyond the Standard Model, such as dark matter and dark energy.
