Quantum Field Theory
In quantum field theory (QFT) we combine quantum mechanics and special relativity to come up with one of the most versatile and best tested theories in physics. It has a wide range of applications in fields as diverse as cosmology, particle, and condensed matter physics. QFT provides a natural way of modelling many body systems and explains particle annihilation and creation.Initially we will concentrate on integer spin boson fields such as spin 0 mesons and spin 1 photons. We will examine the properties of vacuum energy and how QFT explains the Casimir effect. We will then look at how QFT is applied to spin 1/2 fermions such as the electron and the neutrino. We will extensively analyse the Dirac equation and examine how electrons couple to photons. We will also derive formulas for electron-electron scattering and the Klein–Nishina formula which provides an accurate equation for the scattering of photons from electrons.
