从规范对称性中出现基本力是我们对物理宇宙最深刻的见解之一。在自然界中,这种对称性仍然隐藏在亚原子粒子内部自由度的空间中。在这里,我们提出了一种在真实空间中实现和研究规范结构的方法,体现在量子态的外部自由度上。我们提出了一个基于环形晶格势的模型,该模型同时考虑了阿贝尔结构和非阿贝尔结构。通过系统的物理运动证明了非平凡的威尔逊环是可能的。基本的物理基础是几何相与规范势的紧密类比,这已被用来创建具有超冷原子内态的合成规范场。通过放大到具有空间可变参数的阵列,可以在位置空间实现离散的规范场,并在宏观尺寸和时间尺度上映射其动力学。
Emergence of fundamental forces from gauge symmetry is among our most profound insights about the physical universe. In nature, such symmetries remain hidden in the space of internal degrees of freedom of subatomic particles. Here we propose a way to realize and study gauge structures in real space, manifest in external degrees of freedom of quantum states. We present a model based on a ring-shaped lattice potential, which allows for both Abelian and non-Abelian constructs. Non trivial Wilson loops are shown possible via physical motion of the system. The underlying physics is based on the close analogy of geometric phase with gauge potentials that has been utilized to create synthetic gauge fields with internal states of ultracold atoms. By scaling up to an array with spatially varying parameters, a discrete gauge field can be realized in position space, and its dynamics mapped over macroscopic size and time scales.
