Although the subject matter is a well established sub-set of undergraduate solid state physics, the main feature of this book is that it develops the concepts of quantum theory for the solid state from basics to a level beyond broader texts in a single, one-stop sourcebook. It is expected that the student will have acquired an appropriate knowledge of relevant mathematics and will have taken previous introductory courses in quantum mechanics and solid state physics. It applies and develops that knowledge further, to build an understanding of three of the most significant topics in solid state...
