Concepts in Quantum Field Theory: A Practitioner's Toolkit - UNITEXT for Physics (Paperback)Victor Ilisie (author)
- We can order this
This book uses less strict yet still formal mathematical language to clarify a variety of concepts in Quantum Field Theory that remain somewhat "fuzzy" in many books designed for undergraduates and fresh graduates. The aim is not to replace formal books on Quantum Field Theory, but rather to offer a helpful complementary tool for beginners in the field. Features include a reader-friendly introduction to tensor calculus and the concept of manifolds; a simple and robust treatment for dimensional regularization; a consistent explanation of the renormalization procedure, step by step and in a transparent manner at all orders, using the QED Lagrangian; and extensive treatment of infrared as well as ultraviolet divergences. The most general (Lorentz invariant) form of Noether's theorem is presented and applied to a few simple yet relevant examples in Quantum Field Theory. These and further interesting topics are addressed in a way that will be accessible for the target readership. Some familiarity with basic notions of Quantum Field Theory and the basics of Special Relativity is assumed.

"The book basically intends to clarify and structure in a very logical manner concepts that can be confusing in Quantum Field Theory by without strict formalities. The material in the book is collected to be helpful as a complementary tool for beginners and not-so-beginners. ... the book is written for advanced undergraduate-graduate students. ... The book is nicely written and will be helpful for interested students." (Farruh Mukhamedov, zbMATH 1339.81002, 2016)
