Quantum mechanics is an imperative academic achievement of the 20th century. It is one of the more complicated fields in physics that has exaggerated our understanding of nano-meter length scale systems vital for chemistry, materials, optics, and electronics. Quantum mechanics has played an important role in photonics, quantum electronics, and micro-electronics. But many more emerging technologies require the understanding of quantum mechanics; and hence, it is important that scientists and engineers understand quantum mechanics better. In the strange world of quantum mechanics the application of visualization techniques is largely pleasing, for it allows us to portray phenomena that cannot be seen by any other means. Visual Quantum Mechanics relies a great deal on visualization as a tool for mediating details knowledge. The book is intended to explain the basic concepts and phenomena of quantum mechanics by means of visualisation. With an introduction to quantum information theory, this book integrates selected topics from atomic physics — spherical symmetry, the hydrogen atom, and particles with spin. There have been tremendous strides in the field of quantum information, this book introduces relativistic quantum theory, emphasizing its important applications in condensed matter physics. It explores relativistic quantum mechanics and the strange behavior of Dirac equation solutions. The book places an emphasis on ideas and concepts, with a fair to moderate amount of mathematical thoroughness. This book will serve as valuable guide to instruct quantum mechanics to graduate students, engineers, as well as for researchers and scientists.
