The discussion centers on the foundational knowledge required to begin studying quantum field theory (QFT). Participants recommend "Quantum Field Theory for the Gifted Amateur" as a suitable introductory text. A solid understanding of quantum mechanics (QM) is emphasized as essential, with the textbook "Modern Quantum Mechanics" by Sakurai suggested for building this foundational knowledge. The discussion highlights the importance of a strong mathematical background and familiarity with classical mechanics and thermodynamics for success in QFT.
PREREQUISITESStudents and professionals in physics, particularly those with a background in mathematics and classical mechanics, seeking to deepen their understanding of quantum field theory.
Then you should start with that. I wouldn't advise anyone to try and tackle QFT without a good grasp of QM at the level of, say, the textbook by Sakurai.bachir1994 said:very uncomfortable in quantum mechanics.
