Yesterday’s ARC Discover Project announcement saw FLEET research and researchers across three Australian universities awarded additional funding. Across five separate grants, over $2.6m new research funding went to projects and facilities led by FLEET researchers, complementing FLEET’s search to develop ultra-low energy electronics and boost related areas of research. Australia’s Minister for Education Dan Tehan yesterday announced almost $285 million …
Almost 120 researchers gathered in UNSW last week to discuss spin and strong-electron correlations in the university’s biennial Gordon Godfrey Workshop. The 2019 Gordon Godfrey Workshop on Spins and Strong Correlations was held at UNSW’s School of Physics for five days from 25 to 29 November. The Gordon Godfrey Workshops, which have been running since 1991, provide a forum for Australian and international researchers to exchange ideas and …
The study of many-body quantum systems with strong inter-particle interactions is of great interest for the understanding of novel materials. Ultracold atomic gases allow the precise tuning of interactions between atoms via a Feshbach resonance. We experimentally realise such gases with fermionic atoms at unitarity exhibiting the strongest interactions allowed by quantum mechanics. Using two-photon Bragg spectroscopy, we study the …
The quantum impurity problem is relevant to a range of different systems in physics, and it continues to be a highly active area of research. In ultracold atomic gases, the impurity problem can be realised by introducing a small number of atoms of a different species into a background gas. The interaction between the impurity and the background medium can …
Polar bubble domains are complex topological defects akin to magnetic skyrmions that can spontaneously form in ferroelectric thin films and superlattices. They can be deterministically written and deleted and exhibit a set of properties, such as sub-10 nm radius and room- temperature stability, that are highly attractive for dense data storage and recongurable nano-electronics technologies. However, possibilities of controlled motion …

FLEET is currently helping to run a Year 10 ‘Future electronics’ course in partnership with John Monash Science School, Victoria. As well as covering the history of semiconductors and computing, and introducing students to Moore’s Law, the course will also be most students’ first introduction to quantum science, and will be Australia’s first introduction to superfluids and topological materials at …
—by Dr Shaun Johnstone (Monash University) and Dr Tapio Simula (Swinburne University of Technology) One of the first things we learn about the absolute temperature scale, measured in degrees Kelvin, is that it’s impossible to get temperatures below Absolute Zero. But in a recent pair of FLEET studies into turbulence, researchers were working in a regime of precisely that: negative …
First observation of excitonic insulator New exotic state was first predicted in 1960s A University of Wollongong / Monash University collaboration has found evidence of a new phase of matter predicted in the 1960s: the excitonic insulator. The unique signatures of an excitonic insulating phase were observed in antimony Sb(110) nanoflakes. The findings provide a novel strategy to search for …

FLEET’s Meera Parish has been named 2019 Outstanding Referee, the only one in Australia, by the influential American Physical Society (APS). The APS selected 143 Outstanding Referees for 2019, each of whom have demonstrated exceptional work in the assessment of manuscripts submitted to the Physical Review journals. The Outstanding Referee program recognises approximately 150 currently active referees each year, and …
Computing has transformed the world, but there is a price: the huge amount of energy being consumed by massive, factory-sized data centres means that information and communications technology (ICT) already consumes about 8% of global electricity, and is doubling every decade. ICT now has the same global-warming contribution as the aviation industry. Tickets At the same time, we are running …
First snapshot of exciton-polariton Bose-Einstein condensation (BEC) in an inorganic semiconductor Unique opportunity to understand details of BEC without statistical averaging Key to fundamental understanding of exciton-polaritons An ANU advance provides never-before-achieved ‘snapshot’ of Bose-Einstein condensation. Previously, observations of exciton-polaritons in a Bose-Einstein condensate were limited to statistical averaging over millions of condensation events. ‘Snapshot’ imaging of polaritons forming a …

A FLEET study led by University of Queensland’s David Colas clarifies recent studies of negative mass, investigating the strange phenomenon of self-interference. Negative mass?? When we think of ‘mass’, we usually consider the ‘inertial’ mass – the resistance of a body to acceleration due to an applied force. For a moving object, its mass is then a simple relationship between …

Two-dimensional turbulence is even more fascinating than its three-dimensional counterpart. Here, the turbulent energy is predicted to go into the formation of increasingly larger size eddies and vortices in a so-called inverse energy cascade process. Hence 2D turbulence exhibits a peculiar self-organization, giving rise to order out of chaos. This project will involve investigating two-dimensional turbulence in a superfluid atomic …

Recent studies at the ANU resolve an outstanding problem in exciton-polariton …
Taking a multiband approach explains ‘electron-hole reverse drag’ and exciton formation Mystifying experimental results obtained independently by two research groups in the USA seemed to show coupled holes and electrons moving in the opposite direction to theory. Now, a new theoretical study has explained the previously mysterious result, by showing that this apparently contradictory phenomenon is associated with the bandgap …
