• Theoretical Physics (programme FPF, N1701 Fyz)

Course objectives

To acquaint students with the quantum theory of free scalar, electromagnetic and spinor fields. The basic idea of the Lagrangian and Hamiltonian theory of classical fields is first laid out in analogy with the theory of systems with a finite number of degrees of freedom. The transition to a quantum description is based on an analogous transition from classical to quantum mechanics.

Syllabus

• Motivation for quantum field theory. The final volume normalization of the free states. General Lorentz transformation. Lorentz group and its subgroups.
  Scalar field. Klein-Gordon equation. Real scalar field. Hamilton's variational principle, Euler-Lagrange equations. Hamiltonian formalism. Energy-momentum tensor. Noether's theorem. Generalization to multi-component fields. Complex scalar field. Quantization of the scalar field, creation and annihilation operators, Fock space. Operators of energy, momentum and charge of the scalar field. Transition to the Heisenberg picture. Commutators and contractions of the field operators.
  Spinor field. Dirac equation . Classical and quantum theory of the spinor field. Anticommutators. Fock space for fermions. Heisenberg picture.

Teaching methods

Students' self-study
Lectures, tutorial sessions, regularly assigned and evaluated home tasks.

Assessment methods

Credit
Active participation on tutorial sessions and the timely completion of home tasks is required. Detailed criteria will be announced by the tutorial lecturer. The exam consists of the main written part and a supplemental oral part.

Language of instruction

Czech

Further comments (probably available only in Czech)

The course can also be completed outside the examination period.

Teacher's information

The attending of lectures is recommended, that of tutorial sessions is compulsory. If a student was absent for serious reasons, the teacher may prescribe him/her an alternative way of fulfilling the duties.
