An introduction to quantum physics: a first course for physicists, chemists, materials scientists, and engineers

This modern textbook offers an introduction to Quantum Mechanics as a theory that underlies the world around us, from atoms and molecules to materials, lasers, and other applications. The main features of the book are:

• Emphasis on the key principles with minimal mathematical formalism
• Demystifying discussions of the basic features of quantum systems, using dimensional analysis and order-of-magnitude estimates to develop intuition
• Comprehensive overview of the key concepts of quantum chemistry and the electronic structure of solids
• Extensive discussion of the basic processes and applications of light-matter interactions
• Online supplement with advanced theory, multiple-choice quizzes, etc.
