标题： Realization of strongly-interacting Meissner phases in large bosonic flux ladders

摘要： 周期性驱动的量子系统可以实现时间独立哈密顿量中不存在的新物质相。 一个重要的应用是合成规范场的工程，这使得中性原子量子模拟器能够进入拓扑多体物理领域。 在本工作中，我们利用中性原子量子模拟器，在半填充的48个站点的大规模玻色通量梯子中实验实现了强相互作用的莫特-迈斯纳相。 通过结合量子气体显微镜和局部基旋转，我们在大系统中以局部分辨率揭示了出现的平衡粒子电流。 我们发现具有特征相互作用标度的螺旋电流，提供了相互作用莫特-迈斯纳相的直接实验证据。 此外，我们将密度相关性与数值模拟进行对比，发现系统的有效温度在隧穿耦合的量级。 我们的结果展示了将周期性驱动的量子系统扩展到大规模强关联相的可行性，为以单原子分辨率和控制探索拓扑量子物质铺平了道路。 显示英文摘要

摘要： Periodically driven quantum systems can realize novel phases of matter that are not present in time-independent Hamiltonians. One important application is the engineering of synthetic gauge fields, which opens the realm of topological many-body physics to neutral atom quantum simulators. In this work, we leverage a neutral atom quantum simulator to experimentally realize the strongly-interacting Mott-Meissner phase in large-scale, bosonic flux ladders with 48 sites at half filling. By combining quantum gas microscopy with local basis rotations, we reveal the emerging equilibrium particle currents with local resolution across large systems. We find chiral currents exhibiting a characteristic interaction scaling, providing direct experimental evidence of the interacting Mott-Meissner phase. Moreover, we benchmark density correlations with numerical simulations and find that the effective temperature of the system is on the order of the tunnel coupling. Our results demonstrate the feasibility of scaling periodically driven quantum systems to large, strongly correlated phases, paving the way for exploring topological quantum matter with single-atom resolution and control.
