Solid state physics

Although there are many books published in solid state physics, there is a wide gap between the active field of research and the concepts
traditionally taught in solid state courses. This book fills that gap. The style is tutorial, simple, and completely self-contained.
Solid State Physics explains to readers the newest advances in the area of condensed matter physics with rigorous, but lucid mathematics. Examples are an integral part of the text, and they are carefully designed to apply the fundamental principles illustrated in the text to currently active topics of research.
