A Goldstone Boson Primer
Abstract
Description
These lectures are an extremely condensed version of the theory of Goldstone bosons, with general features illustrated using a simple model. A more comprehensive version of these lectures, which includes a general discussion of effective theories of Goldstone bosons, including applications to the low-energy behaviour of pions, spin waves (in antiferromagnets and ferromagnets), and to the SO(5) proposal for high-T_c superconductors may be found in hep-th/9808176.
