This project intends to characterise and engineer the fundamental transport properties of atomic superfluids. Lasers and magnetic fields can be used to cool tiny samples of millions of atoms to temperatures a few billionths of a degree above absolute zero. At such cold temperatures they form a superfluid known as a Bose–Einstein condensate, which flows with zero viscosity. Using tailored light fields to trap and guide the atoms, this project plans to build rudimentary atomic circuits and coax the superfluid to flow through a channel between two reservoirs, firstly with thermodynamic gradients, and secondly by building a quantum pump. Together with computer modelling, this would allow us to characterise the microscopic transport properties of superfluids and provide us with an understanding of how to use them in atomtronic devices in the future.

该项目旨在表征和设计原子超流体的基本传输特性，激光和磁场可用于将数百万个原子的微小样本冷却到比绝对零高几亿分之一的温度，在如此低的温度下，它们会形成超流体。该项目计划使用被称为玻色-爱因斯坦凝聚体的零粘度流动来捕获和引导原子，并计划构建基本的原子电路并诱导超流体流过。两个储层之间的通道，首先具有热力学梯度，其次通过构建量子泵与计算机建模一起，这将使我们能够表征超流体的微观传输特性，并让我们了解如何在原子电子设备中使用它们。将来。
