This project aims to harness the ability to control the fundamental interactions which limit the precision of a diamond quantum sensor, enabling more sensitive magnetometry. Quantum sensors are unveiling new insights into nano-scale phenomena. Single atom defects in diamonds have been at the forefront of this revolution in nano-scale sensor technology. A unique capability, spinning diamond quantum sensors at up to 500,000 rpm, fast enough that quantum properties of the defects are preserved during a cycle has been established. This project will address the long-standing problem of nano-scale solid-materials characterisation using rotationally-enhanced quantum magnetic resonance spectroscopy.Read moreRead less
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

This project aims to integrate quantum hyperpolarisation technology into state-of-the-art nuclear magnetic resonance (NMR) systems, potentially boosting the signal by several orders of magnitude. Understanding the structure and function of membrane bound peptides and proteins in cells in their native environments is critical in drug development. However, studying these biomolecules by conventional NMR under ambient conditions is challenging due to sensitivity limitations. The technology developed by this project will be a significant step forward in NMR and the new science enabled may have far reaching consequences for the study of peptides and proteins of live cells for the development of new drugs and anti-biotics, with direct societal benefits and flow-on economic benefits.Read moreRead less
