This project will develop next-generation focused ion beam microscopy and nanofabrication using a novel cold ion source based on photoionisation of a laser-cooled atom beam. The low temperature and complex internal state structure of the constituent atoms combine to allow generation of ions with unprecedented brightness and resolution. We will use three unique and innovative ideas: field ionisation of atoms in so-called 'exceptional' states to reduce chromatic aberration; electron-ion correlations to enhance control of the ions at the nanoscale; and atom-atom interactions to isolate and manipulate individual ions. The new technology will enable advances in semiconductor nanofabrication and material characterisation.Read moreRead less

Quantum metrology with strongly correlated Rydberg gases. The project aims to make the world's most sensitive measurement of high-frequency electric fields, and demonstrate the first quantum-enhanced electric field measurement. It will use quantum entanglement and Rydberg atoms, excited to the very edge of the classical/quantum divide, to reach record sensitivities for fields associated with next generation ultrafast electronic, communication and radar devices.

New technology developed by Australia, Sweden and the United States will be applied to major questions about the application of relativistic quantum mechanics to atomic structure and dynamics and spectroscopy, especially including critical issues in quantum electro-dynamics for atomic physics and applications. Discrepancies in quantum electro-dynamics have dominated international debate for decades, with claimed explanations annually failing to reveal the cause. Also a pattern of discrepancies has been seen at X-ray energies in first row metal atoms, with a similar sign and magnitude. A combined experimental an theoretical investigation will aim to reveal new light on these anomalies and serve to develop our understanding of the universe.Read moreRead less

The project aims to study electron interactions with the hydroxyl radical (OH). OH is formed in plasmas and atmospheric environments when energetic particles interact with water. Emerging applications of plasmas in wastewater treatment, sterilisation and medicine will be built around OH chemistry. The high intensity of OH spectral emissions has made them useful for remote sensing atmospheric phenomena and diagnosing plasma properties. However, the poor understanding of electron interactions with OH limits our ability to reliably interpret these results. This project therefore aims to experimentally study electron interactions with the hydroxyl radical. The measured values will be applied in simulations that clarify the role of electron–OH interactions in plasma-like environments.Read moreRead less
The genes and pathways regulated by the AMYB80 network are involved in Arabidopsis pollen development. Tapetum is the inner layer of an anther essential for pollen formation.
