What preliminary knowledge of QM should I know before learning QFT, or should I learn QFT in parallel with me learning QM?

QM stands for Quantum Mechanics, which is a branch of physics that studies the behavior of particles at a microscopic level. QFT stands for Quantum Field Theory, which is a theoretical framework that combines quantum mechanics and special relativity to describe the behavior of particles and fields.
Yes, it is highly recommended to have a solid understanding of quantum mechanics before delving into quantum field theory. QFT builds upon the concepts and principles of QM and requires a strong foundation in the subject to fully grasp its complexities.
Some key concepts of QM that are important to understand before learning QFT include wave-particle duality, uncertainty principle, superposition, and quantization. It is also helpful to have knowledge of operators, eigenvalues, and wave functions.
Yes, a strong background in mathematics is essential for understanding QFT. It is recommended to have a solid understanding of calculus, linear algebra, and differential equations. Knowledge of group theory and special relativity is also beneficial.
No, it is not possible to learn QFT without any prior knowledge of physics. QFT is a highly advanced and complex field that requires a strong foundation in classical mechanics, electromagnetism, and quantum mechanics. It is recommended to have a thorough understanding of these subjects before attempting to learn QFT.
