论文摘要
尽管在量子气体领域取得了惊人的进展,但他们备受期待的应用之一 - 量子霍尔状态的模拟 - 仍然难以捉摸:到目前为止,所有实验方法都无法达到原子密度和涡流密度之间足够小的比例。在本文中,我们考虑在磁陷阱中旋转rydberg的原子:这些气体具有强大而可调的非本地排斥相互作用和非常低的密度。因此,它们提供了一个出色的平台来达到量子厅政权。基于Lindemann标准和系统长度尺度相互作用的分析,我们表明存在着敷料参数的最佳价值,可最大程度地减少系统的填充因子与其临界价值之间的比率,以使其进入霍尔制度,从而使得超过1000个较现实的情况,从而使得可能达到这一相关阶段。
Despite the striking progress in the field of quantum gases, one of their much anticipated application -- the simulation of quantum Hall states -- remains elusive: all experimental approaches so far failed in reaching a sufficiently small ratio between atom and vortex densities. In this paper we consider rotating Rydberg--dressed atoms in magnetic traps: these gases offer strong and tunable non-local repulsive interactions and very low densities; hence they provide an exceptional platform to reach the quantum Hall regime. Based on the Lindemann criterion and the analysis of the interplay of the length scales of the system, we show that there exists an optimal value of the dressing parameters that minimizes the ratio between the filling factor of the system and its critical value to enter the Hall regime, thus making it possible to reach this strongly--correlated phase for more than 1000 atoms under realistic conditions.
