提出了一种不引入时间调制的全静态方法来实现带电中性粒子的人工磁场。我们的建议包括一维管受谐波捕获势与移动中心。我们表明，这种设置实现了一个人工磁场中的混合实动量空间。我们讨论了如何在该装置中观察到磁场中粒子的特征，例如手征边缘态和量子化霍尔响应。我们发现，在这种设置下，在物理真实的空间中存在长程相互作用时，玻色子的平均场基态可以在混合实动量空间中具有量子化的涡旋，这种具有涡旋的态在物理真实的空间中表现出超固体结构.我们的方法可以应用于各种合成量子物质，包括超冷原子气体，耦合光子腔，耦合波导，激子极化激元晶格。
We propose an all-static method to realize an artificial magnetic field for charge neutral particles without introducing any time modulation. Our proposal consists of one-dimensional tubes subject to harmonic trapping potentials with shifted centers. We show that this setup realizes an artificial magnetic field in a hybrid real-momentum space. We discuss how characteristic features of particles in a magnetic field, such as chiral edge states and the quantized Hall response, can be observed in this setup. We find that the mean-field ground state of bosons in this setup in the presence of long-range interactions in physical real space can have quantized vortices in the hybrid real-momentum space; such a state with vortices exhibits a supersolid structure in the physical real space. Our method can be applied to a variety of synthetic quantum matter, including ultracold atomic gases, coupled photonic cavities, coupled waveguides, and exciton-polariton lattices.
