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.

该项目旨在阐明物质的重要量子态是如何从电子之间的强相互作用中产生的。量子材料是一种不同种类的材料，其不寻常的特性来自于电子之间的强相互作用。许多金属相具有低导电性（坏金属）。其目的是理解和描述物质的量子态，以及它是如何从组成电子中产生的。预期的结果将是特定理论模型的证伪（基于弦理论的技术）和可用于解释实验的概念的发展，包括超冷原子气体。预计未来的好处包括新的见解和概念，可能有助于设计和合成基于超导、热电和磁阻的新材料。
