Astrophysics

Positron Annihilation Spectroscopy

Understanding material defects at the atomic scale using anitmatter.

Validating a quantum information science concept inventory with online learners

A new quantum information concept inventory, QISCIT, has been validated by experts but never tested on students. This project administers it to learners in an online quantum computing course and performs the psychometric analysis needed to turn it into a genuine research-based assessment.

Measuring conceptual understanding in astrophysics: building and validating a new concept inventory

This project develops a new concept inventory for astronomy and astrophysics. The key stages include expert interviews, question design and stastical validation with student cohorts.

Automated marking of astronomy questions: can AI read the night sky?

Since 2024, Large Language Models have become the standard tool used for automated marking of physics exams, especially for hand-written exams and questions which involve diagrams. Nobody has tested them on astronomy questions where students annotate a projection of the night sky. This project benchmarks LLMs against classical computer-vision methods on marking constellation and object identification tasks.

Interactions between antimatter and ultracold atoms

Antiparticles and antimatter have progressed from theory and science fiction to become an important and exciting area of pure and applied science. This fundamental atomic physics project will investigate how antimatter and matter interact by experimentally studying the interaction of positrons (the electron anti-particle) with trapped ultracold rubidium atoms.

The physics (and mathematics) of Artificial Intelligence

What is the environmental impact of using an AI chatbot? It is possible to model this from first principles by considering the GPU energy usage and the water required for cooling data centres. This project aims to estimate the joules of energy, litres of water and grams of carbon dioxide released from each LLM chatbot response.

Mr Lachlan McGinness

Gravimeter data and tidal analysis

The acceleration due to Earth’s gravity is not constant, but varies slightly over time due to the tidal influence of the Sun and Moon. These tidal signals are the largest periodic variations in gravity and are understood theoretically through models that combine celestial mechanics and geophysics.

Femtosecond laser cleaning of Aboriginal rock art

This project develops safe, damage-free laser cleaning for Australian Indigenous rock art and historic stone monuments, removing contaminants without altering surfaces. Using ultrashort pulse lasers at multiple wavelengths, it combines laboratory optimization and field-applicable procedures, in collaboration with heritage partners and Indigenous custodians, to restore and preserve culturally and visually significant sites.

Evaluating the Spin-First Approach to Teaching Quantum Computing

This project analyses pre- and post-test data from students learning quantum computing through the spin-first approach. The aim is to evaluate question reliability, identify learning gains, and help develop a validated concept inventory tailored to this increasingly common teaching method.

Collective quantum enhancement in multiparameter estimation

Collective measurements can enhance multiparameter estimation precision by allowing joint measurements on multiple copies. This project investigates the extent to which collective measurements can enhance estimation precision and how close to the fundamental limit one can get without entanglement.

Measuring quantum measurements: precision limits for quantum detector tomography

Develop new methods to determine the ultimate precision of quantum-detector calibration using detector quantum Fisher information. Projects may explore continuous-variable probes, multi-parameter incompatibility, or error-correction strategies for preserving Heisenberg scaling in realistic noisy measurements.
