Nonequilibrium states of polariton superfluids

这个项目的目的是设计新的非平衡态的极化子超流体，并确定为什么有些比别人更强大。极化激元是存在于半导体薄层中的光和物质的混合粒子。在高密度下，它们形成超流体，表现出量子化的量子池和无摩擦流动。该项目旨在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涌现特性。预期的结果是产生的基础知识，可用于指导设计的极化激元器件，如新的光电器件发射和控制光。

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.
