ABOUT THIS BOOKTransport in Condensed Matter offers a clear and comprehensive introduction to the principles that govern how charge and spin move through condensed-matter systems. The book opens with linear response theory, Green's functions, and the Boltzmann transport equation, essential tools for understanding electronic behaviour in solids. It then develops perturbation theory and diagrammatic methods, followed by a detailed treatment of impurity scattering, a crucial but often neglected ingredient in realistic transport calculations.
