This project aims to contribute to understanding the physics of quantum many-body systems. A complete understanding of phase transitions in strongly interacting quantum many-body systems is a key step towards solving several open problems in modern physics (eg high temperature superconductors). However, they are extremely difficult to study theoretically or in traditional experiments, due to the underlying strong quantum correlations. This project plans to take an alternative approach using ultra-cold helium atoms in an optical lattice to form an analogue quantum simulator. This would provide access to a new experimental observable: many-body correlation functions, which should yield new insights. Understanding such systems more deeply may lead to the development of new quantum technologies based on this science.

这个项目旨在帮助理解量子多体系统的物理学。对强相互作用量子多体系统相变的完全理解是解决现代物理学中若干开放问题（如高温超导体）的关键一步。然而，由于潜在的强量子相关性，它们在理论上或在传统实验中非常难以研究。该项目计划采用另一种方法，在光学晶格中使用超冷氦原子来形成模拟量子模拟器。这将提供一种新的实验观察：多体相关函数，这将产生新的见解。更深入地了解这样的系统可能会导致基于这门科学的新量子技术的发展。
