1. Formalism of the second quantization

Free and self-interacting electron field; expression for the energy of a multiparticle function in the Hartree-Fok approximation.

2. Hamiltonian of quantum electrodynamics

Electron-positron field quantization; charge symmetry, calibration invariance.

3. Positronium

Virtual and real annihilation, exchange of one and two photons.

4. Radiation correction

Common perturbation method, Feynman space-time approach, electron self-energy, vacuum polarization, mass and charge renormalization, anomalous magnetic moment of an electron, Lamb's shift.

5. Electroweak interactions at low energies

Beta decay - Fermi type theory. Rough outline of Glashow-Salam-Weinberg theory and its consequences. Electro-weak neutral currents and their detection on atomic spectra.
