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.

该项目的主要目的是回答关于多体量子系统的涌现非平衡（NEQ）现象，特别是多体局域（MBL）相的关键问题。这将通过设计和建造新一代的冷原子装置来实现，该装置可以在点状无序势中产生2D量子气体，并对所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一种新的局域状态的相互作用多体系统在有限的温度称为MBL。MBL的研究兴趣的出现，因为它可以防止热化，即使在相互作用多体系统。利用近年来发展起来的基于物质波干涉的实验方法，我们将揭示二维MBL系统中的动力学现象。
