Introduction to Quantum Fields on a Lattice (Cambridge Lecture Notes in Physics)

This book provides a concrete introduction to quantum fields on a lattice: a precise and non-perturbative definition of quantum field theory obtained by replacing the space-time continuum by a lattice. Topics covered include quark confinement, chiral symmetry breaking in QCD, quantized non-abelian gauge fields, scaling and universality. The author also discusses the results of simulations on computers.
