Simulating unconventional quantum phases using valence bond states

量子磁性是许多重要技术材料的核心，但在目前的大多数应用中，只使用了磁性的经典性质。未来固态设备充分利用量子干涉效应的潜力的进展将取决于我们对理论理解的改进。量子磁铁的数值研究可以帮助我们推进这一领域的知识，但在许多关键方面，目前的计算技术不能胜任这项任务。基于局部电子纠缠对的新算法可能会为我们提供探索一些最奇特的磁性行为所需的工具。

Quantum magnetism lies at the heart of many technologically important materials, but in most current applications only the classical properties of the magnetism are used. Progress toward future solid-state devices that exploit the full potential of the quantum interference effects will depend on improvements in our theoretical understanding. Numerical studies of quantum magnets can help to advance our knowledge in this area, but in many crucial ways current computational techniques are not up to the task. New algorithms, based on entangled pairs of local electrons, may provide the tools we need to explore some of the most exotic magnetic behaviours.
