Description

To introduce the student to introductory topics in quantum mechanics. The formal rules of quantum mechanics are introduced. It is shown how observable quantities such as position, momentum and angular momentum are represented by operators. The properties of these operators are studied. The angular momentum operators are studied in detail leading to a series of applications of the wave equation to 1-, 2- and 3- dimensional physical systems. Emphasis is placed on the central potential and the energy and angular momentum properties of the Hydrogen atom are studied. Simple perturbation methods for solving non-trivial problems are introduced and applications of these methods to atomic and molecular systems are examined.

Learning Outcomes

1. Demonstrate an understanding of how quantum states are described by wave functions;
2. Solve one-dimensional problems involving transmission, reflection and tunnelling of quantum probability amplitudes;
3. Explain the significance of operators and eigenvalue problems in quantum mechanics;
4. Identify and construct the wavefunction for the hydrogen atom and explain the significance of angular momentum operators in atomic physics.
5. Solve the Schrödinger equation and describe the properties of a single particle in one, two and three dimensional potentials
6. Apply first and second order perturbation theory to simple systems
