The project aims to investigate the interplay between pairing (superfluidity) and pattern formation (eg stripes) in quasi-two-dimensional quantum systems. The close proximity of these phases is a recurring theme in layered materials which could hold the key to understanding phenomena such as high temperature superconductivity. The project plans to investigate these phases in dipolar gases, which provide a clean, controlled environment for novel many-body phenomena. Within this setting, it plans to test established theories of pairing and develop accurate descriptions of density modulations, thus providing fundamental insights into strongly correlated systems. The new states of matter discovered in the project could form the basis for new quantum devices; in particular, a deeper understanding of stripe phases may allow us to use them for data storage.

该项目旨在研究准二维量子系统中配对(超流)和图案形成(如条纹)之间的相互作用。这些相的接近是层状材料中反复出现的主题，这可能是理解高温超导等现象的关键。该项目计划研究偶极气体中的这些相，这为新的多体现象提供了一个干净、可控的环境。在这种背景下，它计划测试已建立的配对理论，并开发对密度调制的准确描述，从而提供对强关联系统的基本见解。在该项目中发现的物质的新状态可能构成新的量子设备的基础；特别是，对条带相的更深入了解可能会让我们将其用于数据存储。
