Quantum mechanics is a branch of physics that studies the laws of the dynamics of microscopic particles. It is a fundamental theory for investigating the structure and properties of atoms, molecules, atomic nuclei and elementary particles. It has already been widely applied in related disciplines such as chemistry, biology, and many modern technologies. This course introduces the basic principles of quantum mechanics and the simple application of the Schr？dinger equation. The specific main contents include the statistical interpretation of wave functions, time-independent Schrodinger equation, the matrix form of quantum mechanics, the three-dimensional hydrogen atom model, angular momentum, spin and identical particles, etc.
