Geometrically frustrated magnets are materials in which the interactions between magnetic moments are in competition and so cannot be simultaneously satisfied. Such systems are hindered from forming magnetic order and, at low temperatures, can instead form highly correlated states called "spin liquids". This project will study critical phenomena at unconventional phase transitions in frustrated magnets and related systems, such as dimer models, as well as the emergence of strongly correlated dynamics far from equilibrium.

几何受阻磁体是磁矩之间相互作用相互竞争的材料，因此不能同时满足。这样的系统会受到阻碍，无法形成磁序，而在低温下，可能会形成高度相关的状态，称为“自旋液体”。这个项目将研究受阻磁体和相关系统中非常规相变的临界现象，例如二聚体模型，以及远离平衡的强关联动力学的出现。
