Modelling Superconducting Quantum Devices. The capability to incorporate quantum mechanical systems into electronic circuits leads to devices with fundamentally new properties. These devices are very sensitive to their environment, so can be used as sensitive sensors. In the extreme, with many such devices connected together, it would lead to a full scale quantum computer, which has the capacity to perform tasks that are unfeasible on an ordinary computer. This proposal aims to characterise ....Modelling Superconducting Quantum Devices. The capability to incorporate quantum mechanical systems into electronic circuits leads to devices with fundamentally new properties. These devices are very sensitive to their environment, so can be used as sensitive sensors. In the extreme, with many such devices connected together, it would lead to a full scale quantum computer, which has the capacity to perform tasks that are unfeasible on an ordinary computer. This proposal aims to characterise quantum electronics from a theoretical perspective, complimentary to experimental efforts that will soon begin at the University of Queensland.Read moreRead less
Quantum phases of matter driven by strong electronic correlations in complex molecular crystals. This project will provide understanding of organic materials where the physical properties are determined by the interactions between electrons rather than by the behaviour of individual electrons (as in the current generation of electronic devices).

This project will provide understanding of organic materials where the physical properties are determined by the interactions between electrons rather than by the behaviour of individual electrons (as in the current generation of electronic devices). Such fundamental understanding would allow us to create radical new technologies that might change lives comparably to the benefits that silicon based technologies have brought us in the last few decades. This project will generate fundamental new understanding of the deep physical principles at play in strongly correlated organic molecular materials (with implications for technologies on the timescale of decades).Read moreRead less
The bad metallic state in quantum materials. The project seeks to elucidate how an important quantum state of matter emerges from strong interactions between electrons. Quantum materials are a diverse class of materials whose unusual properties emerge from the strong interactions between electrons. Many have metallic phases with a low electrical conductivity (bad metals). The aim is to understand and characterise this quantum state of matter and how it emerges from the constituent electrons. An ....The bad metallic state in quantum materials. The project seeks to elucidate how an important quantum state of matter emerges from strong interactions between electrons. Quantum materials are a diverse class of materials whose unusual properties emerge from the strong interactions between electrons. Many have metallic phases with a low electrical conductivity (bad metals). The aim is to understand and characterise this quantum state of matter and how it emerges from the constituent electrons. An expected outcome will be falsification of specific theoretical models (based on techniques from string theory) and development of concepts that can be used to interpret experiments, including on ultra-cold atomic gases. Projected future benefits include new insights and concepts that may aid the design and synthesis of new materials for applications based on superconductivity, thermoelectricity and magnetoresistance.Read moreRead less
Emergent quantum matter in multinuclear coupled coordination clusters. This project aims to understand how novel quantum states, such as topological spin liquids, emerge and how to control these emergent properties. Emergence is the observation that collections of objects can display very different properties from the individual objects: a water molecule is not wet; a neuron is not conscious. Understanding and controlling the emergent properties of materials has enormous potential applications f ....Emergent quantum matter in multinuclear coupled coordination clusters. This project aims to understand how novel quantum states, such as topological spin liquids, emerge and how to control these emergent properties. Emergence is the observation that collections of objects can display very different properties from the individual objects: a water molecule is not wet; a neuron is not conscious. Understanding and controlling the emergent properties of materials has enormous potential applications from the lossless transport of electricity to next-generation computers. The magnetic systems to be studied are some of the simplest systems that show emergent quantum behaviours. Beyond the intrinsic scientific value of the questions, the exotic states the project seeks to engineer have potential applications in quantum computers.Read moreRead less
Designing and controlling superconducting circuits for quantum information processing. Superconducting circuits are the quantum version of the standard electric circuits and, as the electric circuit did for the electronics industry, they promise a revolution for quantum technologies. This project aims to design superconducting circuits that are more robust to noise and useful for quantum information processing.

Trouble at the bottom: exploring the limits of Fermi liquid theory through dimensionless ratios. Ratios allow us to understand how big we expect something to be. This project will discover new ratios in materials that are difficult to understand, but have remarkable properties that could lead to dramatic new technologies if we understood them better.
Quantum many-body theory of electrical and thermal transport properties of strongly correlated electron materials. New advanced electronic materials conduct heat and electricity via novel mechanisms that must be described via quantum theory. Understanding and modelling these material properties may lead to design of better materials for use in environmentally friendly refrigerators and power generators that do not require mechanical parts.
