Unit description
This unit introduces basic thermodynamic principles and connects them with the physical laws and the statistical nature of the microscopic world governing the behaviour of the matter around us. We start out with the concept of temperature and investigate the emergence of the Boltzmann factor in the canonical ensemble. We then proceed with the kinetic theory of gases and discuss transport properties and thermal diffusion. The first and second law of thermodynamics form the foundation for understanding the basic working principles of thermodynamic engines. We next introduce three key pillars of statistical physics: the equipartition theorem, partition functions and the influence of distinguishability on the counting statistics of particles. This sets us up for a discussion of basic solid-state phenomena as they were known in early 20th century, including Debye theory of the heat capacity of solids, the basics of Drude transport theory and Sommerfeld’s electron model. In order to understand more intricate properties of solid crystals, the periodic nature of the underlying crystal lattice must be considered. The unit will first introduce the 1D solid as a model system for illustrating the basic consequence of having a periodic lattice. The powerful concept of reciprocal lattice is introduced and subsequently generalized to all three dimensions, with specific examples given for the different cubic lattice structures. Wave scattering by crystals and its connection to the reciprocal lattice is discussed with particular view to the X-ray experiment on offer in the labs. Electronic properties are mapped to the existence of band structure and the emergence of band-filling patterns in different materials. Finally, the unit concludes with a discussion of a couple of cutting-edge research topics in modern solid-state physics. |

On successful completion of this unit, you will be able to:
The 'estimated time on task' for each assessment item is an estimate of the additional time needed to complete each assessment outside of all scheduled learning activities. These estimates assume that you actively engage with all scheduled learning activities and spend an additional 31 hours of self-led study during the session. If you receive special consideration for the final exam, a supplementary exam will be scheduled after the end of the normal exam period. By making a special consideration application for the final exam you are declaring yourself available for a resit during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments. Please ensure you are familiar with the policy prior to submitting an application. Approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination.
There are no hurdle tasks specified in this unit. Consequently, the requirement to pass is to obtain an overall mark of at least 50% across the three assessment components.

In Week 9 you will submit your written work on a set of problems. In conjunction with this you will also be asked to present and discuss one of the problems in a viva type assessment. The problems that contribute to the submission will be released in blocks as we complete the relevant sections of content. The problem that you will be asked to present will not be known beforehand. More details on this assessment, including a rubric, will be presented in class at the start of the unit.
Students will have to conduct four out of the following experiments available in the practical part of PHYS3180:
