Physics 137A is the first (upper division) semester of Quantum Mechanics. This is a four unit course.
Overview
As a first pass at introductory quantum mechanics for most students, Physics 137A is a truly mind-blowing course which reveals the fundamental weirdness governing the universe. One can expect to learn quantum mechanics through its various formulations to describe the ever elusive “wavefunction,” which governs the inherently probabilistic dynamics of quantum systems. Using the all-important Schrödinger equation, Physics 137A explores what happens to particles in free space, infinite wells, and quadratic “harmonic oscillator” potentials, among others. The class uses lessons from these toy models to derive the level scheme of the hydrogen atom from basic principles. In addition, the class explores the uncanny valley produced by the at-once intuitive and elusive concept of spin, a discussion which yields to an example of quantum entanglement.
Prerequisites
Physics 5A, Physics 5B, and Physics 5C or Physics 7A, Physics 7B, and Physics 7C.
