Course description and aims
This course addresses quantum mechanics, the foundation of modern engineering. The instructor will explain that particles such as electrons behave as waves in microscopic systems and lead to the Schrödinger equation, which mathematically describes the wave-like behavior of matter. The instructor will also discuss subjects such as the properties of wave functions, operations for quantization, and the uncertainty principle. The Schrödinger equation will be solved to investigate bound states in quantum wells and quantum tunneling in potential barriers. Further the instructor will discuss harmonic oscillators and central force fields, leading to concepts and mathematics specific to quantum mechanics, such as state vectors and angular momentum. The instructor will reveal the structure of hydrogen atoms and explain the electron configuration of many-electron systems. Also, perturbation theory will be discussed as a method for approximating the Schrödinger equation.
Quantum mechanics is necessary in the field of chemistry and materials engineering related to such things as semiconductors to analyze the behavior of electrons and holes. Quantum computers and other quantum information processing also require knowledge of quantum mechanics. On the other hand, quantum mechanics is said to be difficult to grasp for introductory students. This course provides explanations for an efficient mastery of quantum mechanics, and students will develop a foundation for utilizing and applying it in various fields by completing numerous exercise problems.
