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.

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
