Course Objective

In this quantum physics course you will learn the basics of quantum mechanics. We begin with de Broglie waves, the wavefunction, and its probability interpretation. We then introduce the Schrödinger equation, inner products, and Hermitian operators. We also study the time-evolution of wave-packets, Ehrenfest's theorem, and uncertainty relations.

In this quantum physics course you will acquire concrete knowledge of quantum mechanics by learning to solve the Schrödinger equation for important classes of one-dimensional potentials. We study the associated energy eigenstates and bound states. The harmonic oscillator is solved using the differential equation as well as algebraically, using creation and annihilation operators.

In this quantum physics course you will learn the basic concepts of scattering phase-shifts, time delays, Levinson's theorem, and resonances in the simple context of one-dimensional problems. We then turn to the study of angular momentum and the motion of particles in three-dimensional central potentials. We learn about the radial equation and study the case of the hydrogen atom in detail.
