This project aims to design novel nonequilibrium states of a polariton superfluid and to identify why some are more robust than others. Polaritons are hybrid particles of light and matter that exist in thin layers of a semiconductor. At high densities they form a superfluid, exhibiting quantised whirlpools and frictionless flow. The project aims to realise these states in the laboratory and to address one of the challenges of physics: predicting and controlling the emergent properties of materials far from equilibrium. The anticipated outcome is the generation of fundamental knowledge that could be used to guide the design of polaritonic devices such as novel optoelectronic devices for emitting and controlling light.

该项目旨在设计极化激元超流体的新的非平衡状态，并确定为什么有些状态比另一些状态更健壮。极化子是光和物质的混合粒子，存在于半导体的薄层中。在高密度时，它们形成超流体，表现出量化的漩涡和无摩擦的流动。该项目的目标是在实验室中实现这些状态，并解决物理学的挑战之一：预测和控制远离平衡的材料的紧急性质。预期的结果是产生可用于指导极化电子器件设计的基本知识，例如用于发射和控制光的新型光电子器件。
