Quantum Field Theory

PHY 4030

Quantum Field Theory (QFT) studies the quantization of systems with infinitely many degrees of freedom. It is the foundation of the physics of elementary particle (the standard model) and condensed matter. Techniques developed in QFT such as the path integral, perturbation theory, quantization of gauge fields, and renormalization group, are used in many areas in and outside physics, for example in mathematical finance.
