Quantum materials are an exciting class of systems which display exotic phases of matter arising from unusual interactions which cannot be predicted by existing theories. By tuning these interactions via external parameters, exotic phases of matter can be stabilized and their different components can be explored. Furthermore, in controlling these systems, one could enhance a specific physical property which may be desirable in future applications. This project aims to explore experimentally emergent phases of quantum matter in novel materials in order to understand their fundamental interactions. The research will combine a series of experiments in extreme conditions of ultra-high magnetic fields, low temperatures and applied pressure using high-resolution transport and thermodynamic measurements. This study will explore systems with strong magnetic and electronic correlations such as metallic and geometrically frustrated magnetic lattices to understand how conduction electrons respond to frustrated interactions. Other systems will include those close to electronic instabilities and where their quantum limit can be reached in high-magnetic fields to stabilize new correlated electronic states of matter. The proposed projects will generate significant insight into the manipulation of electrons and spin degrees of freedom which is relevant for the development of future quantum electronics and computing.

量子材料是一类令人兴奋的系统，它显示了由不寻常的相互作用产生的物质的奇异相，这些相互作用无法用现有理论预测。通过外部参数调整这些相互作用，可以稳定物质的奇异相，并可以探索它们的不同成分。此外，在控制这些系统时，可以增强特定的物理性质，这在未来的应用中可能是期望的。该项目旨在探索新材料中量子物质的实验涌现阶段，以了解它们的基本相互作用。该研究将结合联合收割机在超高磁场、低温和外加压力的极端条件下使用高分辨率传输和热力学测量进行的一系列实验。这项研究将探索具有强磁和电子相关性的系统，如金属和几何挫折磁晶格，以了解传导电子如何响应挫折相互作用。其他系统将包括那些接近电子不稳定性的系统，以及在高磁场中可以达到量子极限以稳定物质的新相关电子态的系统。拟议的项目将产生对电子操纵和自旋自由度的重要见解，这与未来量子电子学和计算的发展有关。
