The main purpose of this project is to answer key questions about emergent non-equilibrium (NEQ) phenomena ofmany-body quantum systems, in particular the many-body localised (MBL) phase. This will be achieved by designingand constructing a new generation of cold-atom apparatus that produces 2D quantum gases in point-like disorderedpotentials with near-arbitrary control of the imposed disorder. Recent theoretical and experimentalwork has identified a novel localised state of interacting many-body systems at finite temperatures called the MBL.The research interest in MBL arises because it can prevent thermalisation even in interacting many-body systems. With theexperimental method based on matter-wave interferometry that we have developed in recent years, we will observenovel dynamical phenomena in 2D MBL systems.

本项目的主要目的是回答关于多体量子系统的紧急非平衡（NEQ）现象的关键问题，特别是多体局域相（MBL）。这将通过设计和构建新一代冷原子装置来实现，该装置可以产生点状无序势的二维量子气体，并且可以对施加的无序进行近乎任意的控制。最近的理论和实验工作已经确定了在有限温度下相互作用的多体系统的一种新的局部状态，称为MBL。MBL之所以引起人们的研究兴趣，是因为它即使在相互作用的多体系统中也能防止热化。利用近年来发展起来的基于物质波干涉测量的实验方法，我们将观察到二维MBL系统中新的动力学现象。
