Supplier department: Department of Theoretical Physics and Astrophysics - Physics Section - Faculty of Science **Course Enrolment Limitations**- The course is also offered to the students of the fields other than those the course is directly associated with.
**fields of study / plans the course is directly associated with****Course objectives**- Relativistic scalar and vector field equations. Second quantization. Quantum theory of the free electron: spinors, Dirac equation, electrons and positrons. Propagator in spacetime and momentum space representation. Quantum theory of the free electromagnetic field. Interaction picture, perturbation theory of interacting quantum fields. Quantum electrodynamics - general formalism: propagators, Feynman diagrams and rules how to calculate with them. Scattering in an external potential, pair creation, Compton scattering, electron scattering, vacuum polarization and electron self-energy. Exact propagators and vertex functions. Renormalization. Aims: knowledge of the scalar and the Dirac wave equation; Fock state of particle states; ability to construct simple Feynman diagrams; basic understanding of the principles of renormalization
**Learning outcomes**- after absolving the lecture the students • - know the Klein-Gordon and the Dirac equations and the mechanism of quantum field theory • - are able to draw simple Feynman diagrams and calculate the corresponding transition amplitudes • - are familiar with the principle and techniques of renormalization
