Quantum field theory I

1. Introduction: Fundamental motivations for quantum field theory,
Natural units of measure, Overview of the Standard Model of particle physics.

2. Classical Field Theory: Lagrangian and Hamiltonian formulation.

3. Symmetry Principles: Elements of group theory, Lie groups, Lie Algebras, group representations,
Lorentz and Poincaré groups.

4. Noether theorem: conserved currents, conserved charges, the conserved charges of the Poincarè group and their interpretation.

4. Canonical quantization of  real and complex scalar fields.  Creation and annihilation operators. Fock space. Bose statistic. Heisenberg picture field. Realization of symmetries in the quantum theory.

5. Spinorial representations of the Lorentz group. Weyl, Majorana and Dirac spinors and their wave equations. Quantization of the Dirac field. Anticommutation relations and Fermi statistics. 

Required prior knowledge: Electrodynamics, Special relativity, Quantum Mechanics I and II.
