The focus of this course is lattice simulations of Quantum Chromodynamics (QCD), the gauge field theory of the strong interaction between quarks and gluons. The lattice formulation of QCD is introduced along with the techniques necessary to extract physical observables. Simpler systems, such as scalar field theories, are used to illustrate formulating theories on a lattice. The topics which will be covered include

The Computer Lab exercises will involve simulating QCD. Initially, you will be expected to write your own programs for simulating simpler systems: the harmonic oscillator in 1 dimension and scalar field theory in 2+1 dimensions. For QCD an existing software package will be used.
