Summary
Multi-kilohertz laser for attosecond and ultrafast science. Griffith University's Australian Attosecond Science Facility was established 12 years ago to facilitate internationally leading research into strong-field laser science. The facility is unique in Australia as it has the capability to precisely manipulate highly-amplified and ultra-short light pulses to investigate the dynamics of matter.

Griffith University's Australian Attosecond Science Facility was established 12 years ago to facilitate internationally leading research into strong-field laser science. The facility is unique in Australia as it has the capability to precisely manipulate highly-amplified and ultra-short light pulses to investigate the dynamics of matter. The scientific outputs from the facility have delivered important new scientific advances in strong-field physics enabling the development of new technologies. This grant will be used to procure an upgraded laser system enabling an order of magnitude enhancement of the output light for the next-generation research and maintaining international competitiveness of Australian investigators in this field.Read moreRead less
Atomic scale ion microscopy via laser cooling and correlated imaging. 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.

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

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

Summary
Ground station facility for membership of the atomic clock ensemble in space mission. This is a unique opportunity for Australian membership of a high profile space mission involving atomic clocks on board the International Space Station and in the world's best frequency and time laboratories. The results obtained will lead to a better understanding of the unification of quantum mechanics and relativity as well as aspects of fundamental Earth metrology.
A southern hemisphere ground station for the Atomic Clock Ensemble in Space mission. Australia is aiming for membership in the high-profile space mission involving atomic clocks on-board the International Space Station. The mission will test aspects of special and general relativity, searching for tell-tale signs of new physics. This project will construct an atomic fountain clock and install a microwave-satellite link to meet the goal.

Summary
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.

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. The project aims to build on the existing Australian research strengths in photonics, atomic physics and quantum sensing, with the potential to provide a disruptive technological breakthrough in the measurement of ultra-high-frequency electric fields, and establish a high profile research effort in the field of strongly correlated quantum gases.Read moreRead less

This project aims to develop a new generation of bright, laser-like x-ray sources for laboratory use. X-ray sources underpin key diagnostic techniques in materials science, advancing applications from structural engineering through to ore processing and energy storage. However, the limited brightness of present-day laboratory x-ray sources restricts the utility and range of these diagnostic techniques. This research intends to use intense lasers to create microscopic plasmas and drive high harmonic generation. The high harmonic generation process is already used to create laser-like ultraviolet light. By optimising the characteristics of the plasma medium, the project aims to extend bright high harmonic generation to the x-ray regime.Read moreRead less
