Thermal and Statistical Physics (PHYS6020)

This course has been adjusted for remote participation in Sem 1 2021 due to COVID-19 restrictions. On-campus activities will also be available.

Thermal physics deals with collections of large numbers of individual particles such as the air in a balloon, water in a lake, electrons in a chunk of metal and photons emitted from the sun. Many properties of these collections are independent of atomic details: examples are the direction of heat flow, that liquids more readily boil at lower pressure, and that the maximum efficiency of an engine depends upon temperature range and not the working fluid and the set of principles that govern these generic properties is referred to as classical thermodynamics. Other properties do depend upon atomic details - the framework by which we relate the quantum behaviour of one individual particle and to properties of a collection of large number of these particles is referred to as statistical mechanics. From understanding the greenhouse effect to the blackbody radiation left over from the Big Bang, no other physical theory is used more widely through out science than thermal physics.

This course provides an introduction to classical thermodynamics, with applications in materials science & engineering and earth science, as well as statistical thermodynamics, with applications in solid state physics and astrophysics.

Note: Graduate students attend joint classes with undergraduates but are assessed separately.

## Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

1. Identify, critically analyse and describe the statistical nature of concepts and laws in thermodynamics, in particular: entropy, temperature, chemical potential, free energies, partition functions.
2. Expertly use statistical physics methods, such as Boltzmann distribution, Gibbs distribution, Fermi-Dirac and Bose-Einstein distributions to solve complex problems in physical systems.
3. Apply at an advanced level the concepts and principles of black-body radiation to analyze radiation phenomena in thermodynamic systems.
4. Apply at an advanced level the concepts and laws of thermodynamics to solve problems in thermodynamic systems such as gases, heat engines and refrigerators etc.
5. Critically analyze phase equilibrium condition and identify types of phase transitions of physical systems.
6. Identify, critically analyse and transmit knowledge about the connections between thermal physics and various branches of physics.
7. Demonstrate autonomy and expert judgement in the design, construction and execution of experiment and/or theoretical investigation; analysing data and explaining any errors; and comparing with theoretical predictions.
8. Use Mathematica; Python, ANU's MakerSpace, Arduino microprocessors & sensors, tools for generating scientific figures/illustrations; generate/analyse data, and compare with and complete a MakerSpace project and an analysis and report of an MD simulation.

## Indicative Assessment

1. Weekly quizzes (5) [LO 1,2,3,4,5,6]
2. Weekly homework (15) [LO 1,2,3,4,5,6,8]
3. MakerSpace Project involving the construction and/or analysis of a thermodynamic engine (20) [LO 2,3,4,7,8]
4. Mid-semester exam (20) [LO 1,2,3,4,5,6]
5. Web-based Molecular Dynamics Project, use of an interactive simulation to construct a quantitative understanding/prediction of material behaviour through data collection and analysis, and scientifically explained in a written report (20) [LO 1,2,3,4,5,6,7,8]
6. FInal exam (20) [LO 1,2,3,4,5,6]

The ANU uses Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. While the use of Turnitin is not mandatory, the ANU highly recommends Turnitin is used by both teaching staff and students. For additional information regarding Turnitin please visit the ANU Online website.

The expected workload will consist of approximately 130 hours throughout the semester including:

• Face-to face component which may consist of 1 x 3 hour lab session plus 2 x 2 hour workshop per week throughout the semester.
• Approximately 46 hours of self-study which will include preparation for lectures, presentations and other assessment tasks.
