7. Course Introduction:

Quantum Field Theory is a fundamental theory in modern theoretical physics, and it is widely exploited to describe theoretical and phenomenological topics of High Energy Physics, theoretical topics in Condense Matter Physics, important topics in Mathematical Physics, and topics in other research fields. As a Major Elective course on fundamental theory, it is devised for excellent advanced undergraduate students.

Quantum Field Theory is usually understood as quantization of classical field theory. In the viewpoint of fundamental principles, it is a sort of combination of both Special Relativity and Quantum Mechanics. Its mathematical form is the reformulation of the Lagrangian （Hamiltonian） form of Classical Mechanics in terms of the operator language. In the viewpoint of physical models, it is understood as a generalization from quantum many-particle system to quantum system with either unfixed number of particles or infinity number of degrees of freedom.

Through the course, students will be able to understand both fundamental concepts and mathematical formalism of quantum field theory. This course will offer students an opportunity to revisit what they have learnt before, for examples, Special Relativity, Electrodynamics and Quantum Mechanics, and learn prior knowledge for their continuous exploration on various topics of modern quantum field theory.

The teaching consists of two parts. In the first part, the scalar field theory will be the focus, and its canonical quantization, symmetries and conservation laws, interacting fields and scattering theory will be presented in detail. The second part is a kind of review and application of the first one. After the canonical quantization of the Dirac spinor field and Maxwell vector field, quantum electrodynamics will be briefly introduced.

Through the course, students will be acquainted with the canonical quantization of quantum fields, and know well the scattering theory, in particular, calculation in terms of Feynman diagrams in the perturbative approach to interacting fields.
