论文摘要
我们在实验中实现了PEIERLS阶段，从而在Rydberg Atoms携带的激发振幅中振幅，并在最小的三个位点的设置中观察到所得的特征性手性运动。我们的演示依赖于偶极交换相互作用的固有自旋轨道耦合，并结合了通过均匀的外部磁场破坏时间反转对称性。值得注意的是，两个位点之间跳跃幅度的相位很大程度上取决于第三个位点的占用，因此导致与密度依赖性PEIERLS相相关的相关跳跃。我们从实验中观察到这种密度依赖性跳跃，并表明激发作为具有非平凡阶段的任何元素颗粒的交换。最后，我们证实了Peierls阶段对Rydberg原子几何排列的依赖性。
We experimentally realize a Peierls phase in the hopping amplitude of excitations carried by Rydberg atoms, and observe the resulting characteristic chiral motion in a minimal setup of three sites. Our demonstration relies on the intrinsic spin-orbit coupling of the dipolar exchange interaction combined with time-reversal symmetry breaking by a homogeneous external magnetic field. Remarkably, the phase of the hopping amplitude between two sites strongly depends on the occupancy of the third site, thus leading to a correlated hopping associated to a density-dependent Peierls phase. We experimentally observe this density-dependent hopping and show that the excitations behave as anyonic particles with a non-trivial phase under exchange. Finally, we confirm the dependence of the Peierls phase on the geometrical arrangement of the Rydberg atoms.
