Quantum Field Theory (QFT) is the basic mathematical framework that is used for a consistent quantum-mechanical description of relativistic systems, such as fundamental subatomic particles in particle physics. The tools of QFT are also used for the description of quasi-particles and critical phenomena in condensed matter physics and other related fields. This course introduces major concepts and technical tools of QFT. The course is largely self-contained and also covers Lagrangian and Hamiltonian formalisms for classical fields, elements of group theory and the path integral formulation of quantum mechanics. The main topics include the second quantization of various free fields using the canonical quantization formalism. Interacting theories and the perturbation theory are introduced within the more advanced path integral quantization formalism. The main focus is on the development of quantum electrodynamics. The last part of the course deals with the advanced concepts related to topological solutions in quantum field theory and their implications for non-perturbative quantum effects. By completing this course, you will obtain knowledge of major concepts and tools of contemporary fundamental physics, that can be employed in a wide range of physics and physics-based research, starting from the description of profound effects in condensed matter physics and ending by the understanding of basic building blocks of the Universe.
