我们证明，经过动态调制的单环谐振器可以用来创建任意维度的合成空间。在这样的系统中，调制的相位可以用来创建高维的光子规范势。作为对这一概念含义的说明，我们证明了二维非平凡拓扑的Haldane模型可以在合成空间中使用三个环来实现。我们的结果指出了一条在低维物理结构中探索高维拓扑物理的途径。这种合成空间中的光子动力学也提供了一种控制光谱的机制。
We show that a single ring resonator undergoing dynamic modulation can be used to create a synthetic space with an arbitrary dimension. In such a system the phases of the modulation can be used to create a photonic gauge potential in high dimensions. As an illustration of the implication of this concept, we show that the Haldane model, which exhibits non-trivial topology in two dimensions, can be implemented in the synthetic space using three rings. Our results point to a route towards exploring higher-dimensional topological physics in low-dimensional physical structures. The dynamics of photons in such synthetic spaces also provides a mechanism to control the spectrum of light.
