In this text intended for a one-year graduate course, Marder (physics, U. of Texas, Austin) comments in the preface that this second edition incorporates the many thousands of updates and corrections suggested by readers of the first edition published in 1999, and he even gives credit to several individuals who found the most errors. He also points out that "the entire discipline of condensed matter is roughly ten percent older than when the first edition was written, so adding some new topics seemed appropriate." These new topics - chosen because of increasing recognition of their importance - include graphene and nanotubes, Berry phases, Luttinger liquids, diffusion, dynamic light scattering, and spin torques. The text also gives more leisurely attention to the topics of primary interest to most students: electron and phonon bond structures.
