Novel 2-photon atom manipulation for ultra-nanoscale processing of diamond. There is intense interest in exploiting diamond's remarkable properties in many fields of science and technology, but fabricating and processing devices remains a major challenge. This project will build on previous work, using a recently discovered novel laser-induced surface phenomenon that enables, for the first time for any material, the exciting prospect of using light to manipulate surface atoms with atomic precis ....Novel 2-photon atom manipulation for ultra-nanoscale processing of diamond. There is intense interest in exploiting diamond's remarkable properties in many fields of science and technology, but fabricating and processing devices remains a major challenge. This project will build on previous work, using a recently discovered novel laser-induced surface phenomenon that enables, for the first time for any material, the exciting prospect of using light to manipulate surface atoms with atomic precision. This project aims to elucidate the mechanisms underpinning the optical interaction to reveal its full potential and use it to address key problems in diamond nano-device fabrication that lie beyond the reach of current techniques. It is expected that the outcomes will directly enhance Australia's current strengths in diamond-based quantum and photonic technologies.Read moreRead less
Pinpointing the hosts of Fast Radio Bursts with UTMOST-2D. This project proposes to localise a sample of detected ‘fast radio bursts’ to their host galaxies (or local progenitors) for the first time. ‘Fast radio bursts’ are impulsive bursts of radio energy, with characteristics consistent with an origin billions of light-years from Earth. If the source of the bursts can be pinpointed, they would offer a unique tool to study the tenuous, otherwise nearly invisible plasma that permeates the interg ....Pinpointing the hosts of Fast Radio Bursts with UTMOST-2D. This project proposes to localise a sample of detected ‘fast radio bursts’ to their host galaxies (or local progenitors) for the first time. ‘Fast radio bursts’ are impulsive bursts of radio energy, with characteristics consistent with an origin billions of light-years from Earth. If the source of the bursts can be pinpointed, they would offer a unique tool to study the tenuous, otherwise nearly invisible plasma that permeates the intergalactic medium. They could also be used as cosmic rulers to measure the expansion history of the Universe. To date, no burst has been associated with a host galaxy at a known distance, and some researchers maintain that fast radio bursts originate from more nearby sources, potentially even within our own Galaxy. The project plans to explore this hypothesis.Read moreRead less
Understanding the enigma of the most energetic particles in the Universe. By combining an innovative Unmanned Aerial Vehicle (UAV)-based calibration technique with the unparalleled sensitivity of future gamma-ray and radio telescope arrays, this project will study astronomical particle accelerators and Dark Matter with unprecedented accuracy. This will afford us a unique view of the Universe' most energetic processes and allow us to study the laws of physics inaccessible to us in the lab. In the ....Understanding the enigma of the most energetic particles in the Universe. By combining an innovative Unmanned Aerial Vehicle (UAV)-based calibration technique with the unparalleled sensitivity of future gamma-ray and radio telescope arrays, this project will study astronomical particle accelerators and Dark Matter with unprecedented accuracy. This will afford us a unique view of the Universe' most energetic processes and allow us to study the laws of physics inaccessible to us in the lab. In the context of interdisciplinary research, the UAV innovation created will also be leveraged against key applications of remote sensing. With these two goals, this project will demonstrate the capabilities of novel Australian technology whilst providing Australia with a unique science use-case in high-energy astrophysics.Read moreRead less
