超冷极性分子远离平衡的量子磁性

Far from equilibrium quantum magnetism with ultracold polar molecules

摘要:

最近的理论指出了如何用超冷极性分子模拟量子磁性的可调模型。在这里,我们表明,目前的分子光晶格实验可以实现量子仿真的三个关键目标,尽管目前远远低于单位填充和量子简并。第一个是验证和基准的模型提出来描述这些系统。第二个是准备相关的和可能有用的国家在很好理解的制度。第三是探索现有理论技术无法实现的多体物理学。我们的建议依赖于一个非平衡协议,可以被视为拉姆齐光谱或相互作用淬火。它只使用任何超冷分子实验中可用的常规实验工具。

英文摘要:

Recent theory has indicated how to emulate tunable models of quantum magnetism with ultracold polar molecules. Here we show that present molecule optical lattice experiments can accomplish three crucial goals for quantum emulation, despite currently being well below unit filling and not quantum degenerate. The first is to verify and benchmark the models proposed to describe these systems. The second is to prepare correlated and possibly useful states in well-understood regimes. The third is to explore many-body physics inaccessible to existing theoretical techniques. Our proposal relies on a non-equilibrium protocol that can be viewed either as Ramsey spectroscopy or an interaction quench. It uses only routine experimental tools available in any ultracold molecule experiment.
