论文摘要
我们提出了一种全静态方法，可以实现一个无需任何时间调节的电荷中性颗粒的人造磁场。我们的提议包括一维管，受到转移中心的谐波陷阱电势。我们表明，这种设置实现了混合房地产空间中的人造磁场。我们讨论在此设置中如何观察到磁场中颗粒的特征，例如手性边缘状态和量化的霍尔响应。我们发现，在物理真实空间中存在远距离相互作用的情况下，玻色子的平均场基态可以在混合房地产空间中量化涡旋；这种具有涡旋的状态在物理真实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，包括超速原子气体，耦合光子腔，耦合的波导和激子 - 波利顿晶格。
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.
