Direct observation of radioactive nuclides from stars and the interstellar medium would provide first experimental constraints on production rate. The concept is to have a global network of magnetometers looking for correlated magnetic field fluctuations that may be caused by strange, and unknown physics. Fundamental tests of quantum mechanics with matter waves We create the coldest stuff in the Universe — a Bose-Einstein condensate BEC — by laser-cooling helium atoms to within a millionth of a degree Kelvin. At these extremely low temperatures particles behave more like waves.
You will use the BEC to study fundamental quantum mechanics and for applications like atom interferometry.

Measuring and modelling free-ion hyperfine fields Motivated by exciting prospects for measurements of the magnetism of rare isotopes produced by the new radioactive beam accelerators internationally, this experimental and computational project seeks to understand the enormous magnetic fields produced at the nucleus of highly charged ions by their atomic electron configuration. Coherent control of quantum-mechanical systems The project studies possibility of the coherent control i. Atomic ionization in super-strong laser fields Using methods of quantum many-body theory to describe elementary processes in atoms and molecules interacting with strong electromagnetic fields.
Attosecond time-resolved atomic reactions We apply the most advanced quantum-mechanical modeling to resolve electron motion in atoms and molecules on the atto-second one quintillionth of a second time scale. Our theoretical modeling, based on a rigorous, quantitative description of correlated electron dynamics, provides insight into new physics taking place on the atomic time scale. The inverse swarm problem with neural networks The traditional approach transport simulation is to measure cross sections and feed them into a code package.
However, some cross sections are very difficult to both measure and calculate. The "inverse swarm problem" seeks to extract these cross sections from transport measruements such as current profiles or annihilation rates.

Electron scattering from surfaces at high energies The project aims at establishing the possibilities of high-energy electron scattering in the analysis of thin layers. How does a quantum system reach equilibrium? The idea of equilibration is ubiquitous throughout nature. This project looks at both equilibration and phase transitions in a Bose-Einstein condensate of metastable helium atoms. Positron applications in medical physics 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. Electron-liquid interface scattering Low temperature plasmas are being exploited for new medical therapy techniques and in engineering applications in agriculture. This project explores the fundamental behaviour of how electrons penetrate a liquid surface, such as the skin of the body.
Optimised atom interferometry for space-based experiments This theoretical physics project aims to optimise the performance of atom interferometry in a space-based environment. Space-based operation requires novel beamsplitting and atomic source production techniques, which will be developed in this project. Fragmentation of molecules by positronium Positronium is a bound state between an electron and a positron. It is hydrogen-like with a binding energy half that of hydrogen.
Positronium has been found to scatter like an electron for the same velocity. Electrons can fragment molecules by temporary attaching leading to fragmentation. This project will explore the fragmentation of molecules in positronium scattering with molecules. Benchmark positron scattering experiments 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.
Experimental determination of the Auger yield per nuclear decay Auger electrons are emitted after nuclear decay and are used for medical purposes. This project aims to obtain a experimental estimate of the number of Auger electrons emitted per nuclear decay. Optical quantum memory An optical quantum memory will capture a pulse of light, store it and then controllably release it.
This has to be done without ever knowing what you have stored, because a measurement will collapse the quantum state. We are exploring a "photon echo" process to achieve this goal. Biophysics Low-temperature plasma nitrogen fixation for enhancing plant growth Plasma agriculture is an innovative field that applies plasma to agriculture processes such as farming, food production, food processing, and food preservation.
