The successful, short textbook gives a clear and concise introduction to solid state physics, covering its phenomena and concepts in a manner suitable for physics majors and non-majors exposed to the topic for the first time. Consequently, each chapter starts with the basic principles and gently progresses to a more advanced level by easy-to-follow explanations and by keeping the mathematical formalism limited to a minimum. This new edition includes the following updates: * New topics: covering developments in the fields of two-dimensional materials and superconductivity * Improved explanations: easier-to-understand descriptions of metallic and covalent bonding, a straightforward proof of Bloch's theorem, a simpler approach to the nearly free electron model, clearer discussion of the temperature-dependent chemical potential * Enhanced pedagogical features: including more than 100 discussion questions, 70 problems, many of which - new! - require numerical solution, and - new! - multiple-choice problems at the end of each chapter with solutions in the book
