The imaging of light and atoms trapped in the potential minima of optical lattices will be a world first, positioning Australia at the forefront of the merging fields of electron microscopy and atom optics, leading to important international recognition and publicity. This project, relevant to the frontier technologies of photonics, atom optics and quantum information processing, will also develop a skills base in surface electron microscopy and laser science by providing high level training for post-graduate and honours students. In addition, the utilisation of optical lattices as micro-environmental cells in electron microscopy will be an important development for in situ studies of the gas phase including chemical reactions.

Quantum properties of high-spin ultra-cold matter. High-spin atomic gases are a new type of ultra-cold matter, with many unique properties akin to the physics of the early universe. The aim of the project is to theoretically investigate these systems to understand the quantum properties and dynamics of such exotic matter, and to obtain experimentally testable predictions.
Building time crystals with ultracold atoms. This project aims to create a new exotic form of quantum matter in which a many-body system of ultracold atoms bouncing on a vibrating mirror spontaneously self-organises its motion with a period tens of times longer than the driving period of the mirror. Such ‘time crystals’ are predicted to be robust against external perturbations and to persist for very long times. The project expects to generate new knowledge on exotic non-equilibrium crystalline ....Building time crystals with ultracold atoms. This project aims to create a new exotic form of quantum matter in which a many-body system of ultracold atoms bouncing on a vibrating mirror spontaneously self-organises its motion with a period tens of times longer than the driving period of the mirror. Such ‘time crystals’ are predicted to be robust against external perturbations and to persist for very long times. The project expects to generate new knowledge on exotic non-equilibrium crystalline phenomena in the time domain, such as many-body localisation with temporal disorder, which has counter-intuitive characteristics such as absence of thermalisation and vanishing direct current transport. Time crystals could provide significant benefits for the storage and transfer of quantum information, and this, and other outcomes may ultimately lead to commercial products.Read moreRead less
Transport and impurity dynamics in a unitary Fermi gas. This project aims to generate new understandings of transport and the behaviour of impurities in a gas of strongly-interacting atoms cooled to nanoKelvin temperatures. By measuring the response of a unitary Fermi gas to disturbances with well-defined momenta and energies, we will map the elementary excitations in both the superfluid and normal fluid phases. From this, the parameters that define how particles and impurities travel through th ....Transport and impurity dynamics in a unitary Fermi gas. This project aims to generate new understandings of transport and the behaviour of impurities in a gas of strongly-interacting atoms cooled to nanoKelvin temperatures. By measuring the response of a unitary Fermi gas to disturbances with well-defined momenta and energies, we will map the elementary excitations in both the superfluid and normal fluid phases. From this, the parameters that define how particles and impurities travel through the system can be determined. Our study will reveal whether the unitary Fermi gas approaches a conjectured quantum limit for perfect fluidity, examine how the properties of the gas depend on impurity concentration and establish new benchmarks for theories of strongly-correlated quantum matter.Read moreRead less

Strong few-body correlations from controllable impurities in quantum matter. This project aims to investigate the role of few-body correlations in quantum matter by using recently developed theoretical approaches to incorporate correlations beyond the scope of traditional theories.

The project expects to gain fundamental insight into quantum few-body correlations in materials by investigating single impurity particles immersed in quantum media, such as highly controllable atomic gases and semiconductors. The significant benefits include the development of novel theoretical approaches and the generation of knowledge that could potentially underpin a new generation of quantum devices.Read moreRead less
Density modulations and superconductivity in two-dimensional quantum gases. The project aims to investigate the interplay between pairing (superfluidity) and pattern formation (eg stripes) in quasi-two-dimensional quantum systems. The close proximity of these phases is a recurring theme in layered materials which could hold the key to understanding phenomena such as high temperature superconductivity. The project plans to investigate these phases in dipolar gases, which provide a clean, controll ....Density modulations and superconductivity in two-dimensional quantum gases. The project aims to investigate the interplay between pairing (superfluidity) and pattern formation (eg stripes) in quasi-two-dimensional quantum systems. The close proximity of these phases is a recurring theme in layered materials which could hold the key to understanding phenomena such as high temperature superconductivity. The project plans to investigate these phases in dipolar gases, which provide a clean, controlled environment for novel many-body phenomena. Within this setting, it plans to test established theories of pairing and develop accurate descriptions of density modulations, thus providing fundamental insights into strongly correlated systems. The new states of matter discovered in the project could form the basis for new quantum devices; in particular, a deeper understanding of stripe phases may allow us to use them for data storage.Read moreRead less

This Fellowship aims to unravel the behaviour of new complex materials by investigating the nature of quasiparticles beyond the current paradigm. The key innovation is the use of trapped atoms, which allows new quantum theories and computational tools to be developed and precisely tested. The new knowledge generated by the Fellowship will advance a range of fields, including condensed matter physics, and could ultimately underpin a new generation of quantum devices featuring robust data memories, where information can be efficiently stored and extracted.Read moreRead less
