Understanding material defects at the atomic scale using anitmatter.

Using the atomic and molecular physics positron beam at the ANU, the student will undertake measurements of positron scattering from simple targets, providing high accuracy data to test recent theoretical calculations.

This experimental project aims to create entangled states of ultracold helium atoms where the entanglement is between atoms of different mass. By manipulating the entangled pairs using laser induced Bragg transitions and measuring the resulting correlations, we will study how gravity affects mass-entangled particles.

This project will construct a 3D optical lattice apparatus for ultracold metastable Helium atoms, which will form an experimental quantum-simulator to investigate quantum many-body physics. A range of experiments will be performed such as studying higher order quantum correlations across the superfluid to Mott insulator phase transition.

This project combines theoretical and experimental research on exciton polaritons in semiconductor microcavities. We investigate emergent quantum phenomena far from equilibrium and their applications for next-generation optoelectronics devices.

This experimental project will focus on nvestigation of strong light-matter coupling and exciton polaritons in novel atomically thin materials.

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.

We are investigating novel effects and applications using positrons and structured surfaces.

This is a multi-faceted project which can be adapted to students at the honours level and above. A number of possibilities exist to perform experiments directed towards improving the use of positrons in medice, mostly focussed on Positron Emission Tomography (PET).
