Condensed matter systems where interactions are strong are inherently difficult to analyze theoretically. The situation is particularly interesting in low-dimen

This book explains the fundamental concepts and theoretical techniques used to understand the properties of quantum systems having large numbers of degrees of f

The book is an introduction to quantum field theory applied to condensed matter physics. The topics cover modern applications in electron systems and electronic

For most of the last century, condensed matter physics has been dominated by band theory and Landau's symmetry breaking theory. In the last twenty years, howeve

This primer is aimed at elevating graduate students of condensed matter theory to a level where they can engage in independent research. Topics covered include
