For most of the last century, condensed matter physics has been dominated by band theory and Landau's symmetry breaking theory. These new physical concepts are so fundamental that they may even influence our understanding of the origin of light and electrons in the universe. In the last twenty years, however, there has been the emergence of a new paradigm associated with fractionalization, topological order, emergent gauge bosons and fermions, and string condensation.
It discusses many basic notions in theoretical physics, which underlie physical phenomena in nature, including a notion that unifies light and electrons. This book is a pedagogical and systematic introduction to the new concepts and quantum field theoretical methods in condensed matter physics. Topics covered are dissipative quantum systems, boson condensation, symmetry breaking and gapless excitations, phase transitions,
