Studying Quantum Field Theory without taking graduate QM?

AI Thread Summary
Studying quantum field theory (QFT) requires a solid foundation in advanced quantum mechanics and classical mechanics, which includes familiarity with Lagrangian and Hamiltonian formalisms. While prior knowledge from undergraduate quantum mechanics and special relativity is beneficial, it may not be sufficient for a rigorous self-study of QFT. Using Sakurai's textbook alongside QFT resources can help, but a graduate-level understanding of quantum mechanics is highly recommended for deeper comprehension. Mastering QFT demands significant dedication, as it is a complex subject. For those seeking only a basic understanding before formal coursework, the current background may suffice.

Hello over the summer I would like to study quantum field theory. I took two semesters of undergraduate quantum mechanics using Griffith's textbook. We covered the entire book in those two semesters. I also know my special relativity pretty well. Is that enough to self study quantum field theory rigorously. I also took a class in graduate classical mechanics and know Lagrangian, Hamiltonian formalism pretty well. Furthermore I have lots of experience with canonical perturbation theory.

I would look at Sakurai concurrently. If/once you are comfortable with the material in Sakurai, then you should be ready to learn and appreciate QFT. For QFT I would highly recommend the book Quantum Field Theory and the Standard Model.

Rigorously? Probably not. You'd be skipping something like two or three classes and building on a foundation that is not particuilarly known for its rigor.
 
If Sakurai might as well be written in Vietnamese for you, as it probably would be if you haven't done a graduate level QM class, I wouldn't recommend it.

Otherwise, have at it, but it will take *dedication* to master QFT. This is not an easy subject. However, that might not be what you are after. If you just want to learn some of the basics and plan on taking a course later in the subject, you should be fine.
 
Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
TL;DR Summary: I want to do a PhD in applied math but I hate group theory, is this a big problem? Hello, I am a second-year math and physics double major with a minor in data science. I just finished group theory (today actually), and it was my least favorite class in all of university so far. It doesn't interest me, and I am also very bad at it compared to other math courses I have done. The other courses I have done are calculus I-III, ODEs, Linear Algebra, and Prob/Stats. Is it a...
