论文摘要
扭曲的范德华(Van der Waals)异质结构后来因其许多非凡的实验性能而引起了人们的关注,以及他们对实现实验室中难以捉摸的物质状态的承诺。我们建议这些系统实际上可以用作稳健的量子模拟平台,该平台可以研究量子材料中强相关的物理学和拓扑。在使这些材料成为多功能工具箱的功能中,它们是通过易于访问的外部参数(例如门控,紧张,包装和扭曲角度)的可调性。实现和控制大量基本多体量子模型的可行性与凝结物理学领域相关;最后,实验读数方案的可用性直接绘制了其富相图进出平衡。这个一般框架使得以模块化的方式坚强地实现和功能化物质的新阶段,从而扩大了可访问物理的景观,并为未来的技术应用持希望。
Twisted van der Waals heterostructures have latterly received prominent attention for their many remarkable experimental properties, and the promise that they hold for realising elusive states of matter in the laboratory. We propose that these systems can, in fact, be used as a robust quantum simulation platform that enables the study of strongly correlated physics and topology in quantum materials. Among the features that make these materials a versatile toolbox are the tunability of their properties through readily accessible external parameters such as gating, straining, packing and twist angle; the feasibility to realize and control a large number of fundamental many-body quantum models relevant in the field of condensed-matter physics; and finally, the availability of experimental readout protocols that directly map their rich phase diagrams in and out of equilibrium. This general framework makes it possible to robustly realize and functionalize new phases of matter in a modular fashion, thus broadening the landscape of accessible physics and holding promise for future technological applications.
