# Quantum Field Theory literature - rigorous and clean [duplicate]

I'm a physics student that is currently having a lecture on Introduction to Quantum Field Theory. The topics covered are:

• Relativistic quantum mechanics
• Elements of classical field theory
• Quantization of free scalar fields
• Interactive Scalar fields: perturbation theory and Feynman diagrams
• Quantization of Dirac Fields and Spin-1 Fields
• Quantum electrodynamics
• Grinding and renormalization

The lecturer did give literature recommendations (Peskin/Schroeder, Aitchison, /Hey and Maggiore), however I believe that for me it would be useful to use literature that gives a different viewpoint on QFT rather than one that focuses on the same approach as the lecture to achieve a more holistic understanding. As far as I am concerned my lecture focuses on introducing the needed mathematical tools and how to use them, which is also the focus of the exercises.

What I now need as an addition to the course would be:

1. Something that explains the physical motivation and teaches the ideas of QFT, for which I think the book of Griffiths would be nice? (it is recommended in the experimental course and his books are nice to read), but objections can be given.

2. Something with a rigorous approach on why the things we use are the the things we want. Maybe something a bit more in the likes of a mathematical textbook would be nice, as I like clear structure, conciseness (which does not mean short, just concise) and proofs.

Of course a book that would merge both would be great, however I have the feeling that this would be hard to achieve.

I am utterly aware that book recommendations like this have been asked for quite a lot. However they are often quite old, with many books very hard to get nowadays and most of questions focus a lot on the books being introductory and easy to understand or being very complete, which is not quite what I am searching for.

Before answering, please see our policy on resource recommendation questions. Please write substantial answers that detail the style, content, and prerequisites of the book, paper or other resource. Explain the nature of the resource so that readers can decide which one is best suited for them rather than relying on the opinions of others. Answers containing only a reference to a book or paper will be removed!
