Quantum Mechanics & Thermal Physics(Adv)

This subject has the following teaching availabilities in 2008:

This subject introduces students to two fundamental areas of physics and is divided into two parts. In the quantum mechanics section, the framework of wave mechanics is established. In thermal physics, concepts such as work, heat, temperature and entropy are introduced. The physics underlying both these components is central to an understanding of many processes in physics, chemistry and engineering.

Students completing this subject will be able to:

• explain the basic principles of quantum physics and the zeroth, first and second law of thermodynamics;

• solve and analyse simple quantum mechanical problems; and

• calculate and interpret the thermodynamic properties of several simple systems.

In addition students will enhance their ability to:

• participate effectively as part of a group in tutorials; and

• plan effective work schedules to meet the deadlines for submission of assessable work and prepare for examinations.

Specific topics to be covered in the quantum mechanics section include the experimental basis of quantum mechanics; wave-particle duality, probability interpretation and the wave function; wavepackets; Schrödinger equation; one-dimensional examples such as potential steps, barriers and wells, linear momentum; operators and expectation values; and an idea of three-dimensional problems and the hydrogen atom. The thermal physics section will cover the zeroth, first and second law of thermodynamics, kinetic theory, the microscopic origin of entropy, heat engines and refrigerators, paramagnetism, phase changes and chemical thermodynamics.
