Field theory has special complexities which may not be common to other fields of research. Symmetry and its breaking are most exotic and sometimes almost mysterious to even those who can normally understand basic physics. This book focuses on presenting a picture of the symmetry and its breaking in quantum field theory.

Presents a unified description of the spontaneous symmetry breaking and its associated bosons in fermion field theory. This title discusses the exact spectrum of the Thirring model by the Bethe ansatz solutions. It examines the boson spectrum in QCD2, and shows that bosons always have a finite mass for SU(Nc) colours.
