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

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

This book presents a simple and clear picture of symmetry and its breaking in quantum field theory by discussing the physics of elementary field theory of fermions interacting by gauge fields, as well as by four body fermion fields. In this respect, the interpretation of the basic field theory is repeatedly done such that physicists, including graduate students, may understand the essential points of symmetry breaking in this textbook. This book also contains a brief description of the lattice field theory even though it is not directly connected to symmetry breaking physics because it may...
