This project aims to study universal phenomena predicted to occur in ultracold Fermi gases confined to move in two dimensions. Universal phenomena are properties or behaviours found in collections of particles that are independent of the microscopic details of the constituents and their interactions. Such universal features can appear in cold atoms, condensed matter systems, nuclear physics and neutron stars, and span vast energy scales. This project’s findings are expected to provide quantitative insights into few-body and many-body phenomena ubiquitous in two-dimensional quantum materials. This may have significance for emerging technologies which exploit quantum effects in lower-dimensional materials.

这个项目的目的是研究超冷费米气体中预计将发生的普遍现象，这些气体被限制在两个维度上运动。普遍现象是在粒子集合中发现的与成分及其相互作用的微观细节无关的性质或行为。这样的普遍特征可以出现在冷原子、凝聚态物质系统、核物理和中子星中，并跨越巨大的能量尺度。该项目的发现有望为二维量子材料中普遍存在的少体和多体现象提供定量的见解。这可能对利用低维材料中的量子效应的新兴技术具有重要意义。
