Physics
This is the definitive text for quantum mechanics beginners! It provides detailed explanations step by step so that people who are learning quantum mechanics for the first time will not get bogged down. The necessary prerequisite knowledge is only mathematics and physics at the university first year level. Based on the experience of the author who was in charge of a lecture for students who are not specialized in physics, we made it easy to reach the topic of atoms (Chapter 5) using only "wave mechanics". After that, in Chapter 6, we will learn the basics of linear algebra and advance to "matrix mechanics." In material science, there are attractive phenomena that are unique to quantum mechanics such as laser light, superconductivity, and magnetism. With the aim of understanding these phenomena, we will provide detailed explanations up to the next level such as second quantization, relativistic quantum mechanics, and quantum entanglement. It is also an ideal book for getting used to before going on to full-scale study of quantum mechanics.
